Cobblestone is made of a natural material and is therefore particularly suitable if you want to design your outdoor area with a combination of paths and plantings. The most common rocks for such a patch are granite, basalt and porphyry. These rocks have a very high strength and ensure your ways an extremely long life.
However, when laying cobblestones, you will be confronted with a few peculiarities that you must follow.
To lay the cobblestones you need chess tools or a mini excavator, a vibrating plate, a rubber and paving hammer as well as a spirit level and tape measure. Their auxiliary materials consist of weed fleece, coarse gravel, laying sand, as well as joint splits or joint sand.
Step 1: the substructure
Hatch your future path 40cm deep. Store the topsoil for reuse separately from the other excavation. Create a 5cm thick layer of coarse gravel that you compact with the vibrating plate.
Lay out the weed fleece on this layer. Then follow another 20cm of coarse gravel, which you also compact thoroughly.
Step 2: the edge boundary
Cobblestone is not laid in the composite like concrete paving. The outer stones are therefore not tip over and must be attached. You can do this by limiting your coarse gravel bed on the flanks with deep shelves in lean concrete laying. But you can also protect the flanks with a bevelled concrete banquet after paving.
Step 3: Laying
Cobblestone is made of natural material and each stone varies in height. Therefore, it is not worthwhile to deduct a uniform grit bed. Use laying sand, which you distribute with the shovel. The final thickness must be adjusted individually for each stone. Fix the stones with a rubber mallet about 8mm higher than the ground level. Check with the spirit level again and again whether the gradient is uniform.
Step 4: Joint Closure and Settlement
Sweep over a special joint sand or grout with a coarse broom over the pavement. When all the joints are filled, water the plaster with the garden hose, which compresses the material in the joints.
Finally, ram the stones with the vibrating plate and rubber pad until you have reached the ground level.


Earth Resistance Meter
This instrument is a Geoscan Research RM15 earth resistance meter loaned by Archaeo-Physics, LLC (data logger) and Ohio Valley Archaeology, Inc. (frame). It consists of two probes connected by a crossbar. Current is injected into the ground from one probe and measured in the other. (Another set of remote probes connected by cables complete the electrical circuit.) The measurements are recorded on a data logger mounted on the crossbar.
A resistance meter is an instrument used to measure how well soil conducts electrical current. Because stones are generally less conductive than soil, measurements taken in the area of buried stone walls will be noticeably different from measurements taken elsewhere. By gridding out an area and taking hundreds of measurements at regular intervals, it is possible to map buried buildings and indeed whole neighborhoods such as the South Hill at Olynthos without digging. This is one of several techniques of geophysical prospection that have revolutionized archaeology.


About NYC CoolRoofs
NYC CoolRoofs was launched in 2009 as a volunteer-based program to support New York City’s efforts to combat climate change. In 2015, the program transitioned to a workforce development training opportunity to provide job-seeking New Yorkers with the opportunity to earn paid work experience and credentials in the construction sector. The program has an annual goal of installing one million square feet of rooftops while engaging local property owners, community partners, workforce training organizations, and volunteers throughout the process.
Benefits of Cool Roofs for Buildings
Reduce roof temperatures
During a typical summer day, flat, black asphalt rooftops can reach temperatures up to 190°F which is 90 degrees hotter than the surrounding air temperature.
Reduce internal building temperatures
Cool rooftops can reduce internal building temperatures by up to 30 percent, making the building cooler and more comfortable during the hot summer months.
Reduce the Urban Heat Island Effect
New York City can be up to five degrees hotter than surrounding areas due to greater amounts of dark surfaces, such as roofs and roads, and less shading from vegetation.
Reduce carbon emissions
Every 2,500 square feet of roof that is coated can reduce the city's carbon footprint by one1 ton of CO2 and help fight climate change.
Improve air quality
Cool roofs lower air pollution and greenhouse gas emissions by reducing power demand.
Extend the lifespan of rooftops and HVAC equipment
A CoolRoof coating better regulates a roof's temperature as compared to typical rooftop surfaces. By decreasing the roof temperature and cooling loads, the life of the rooftop and cooling equipment can be extended.
Request a Cool Roof
This guide is designed to help you determine eligibility for coating your rooftop with us and outlines additional ways in which you can support and get involved with this program and other initiatives. At any point, we are also happy to provide additional technical support and resources to any New York City building interested in installing a cool roof.

Considering a new patio? Maybe you want to spruce up the old driveway with something that has a bit more curb appeal. It’s time to talk pavement and options. Home owners install stone pavers in a wide variety of shapes, sizes, and materials. Bricks, for example, are common stones used to pave walkways, driveways, and pool decks. However, stamped concrete offers a superior solution to pavement. We listed some main reasons why stamped concrete is a better choice for your next pavement project.
Strength Over Time
Newly paved driveways, patios, and pool decks look great when first installed. Ask yourself what they will look like in 10 years? Consider which material is the most durable and will look the best after years of weathering. Rain, constant traffic, and general aging wear down most traditional pavement. Stamped concrete changes the game with a material that actually gets stronger as it cures. As a cohesive paved area, stamped concrete combines beautiful design with a durable and long-lasting solution to pavement.
Weeds: No Thank You!
Individual stones and bricks create upscale looking driveways, walkways, and patios. Installers lay each brick and stone by hand. Unfortunately, the space between the pavers welcomes unwanted grass and weeds. That amazing new brick driveway looks great until it’s polluted with weeds in all the crevices. Think about the costly and time-consuming hassle of spraying for weeds or pulling them by hand every year to keep your pavement looking good. However, stamped concrete offers a solution. Stamped concrete installers pour concrete to create one cohesive body of hardened surface. The stamps create the look of individual stones, without the hassle of real separations.
Another disadvantage of traditional paver stones is that they limit shape options. To achieve curved designs, you need to cut the straight edges of the stones to create the curved perimeter. Stamped concrete installers design a form that can take any shape you want. Don’t worry about working around your existing landscape because each form is custom made. Build a curved pool deck that wraps around your inground pool, or a patio that hugs pre-existing trees. Stamped concrete makes unique shapes and designs much easier and cost efficient than stones.
Avoid Sink Holes
As we mentioned previously, stone pavers don’t maintain their appeal over the test of time. Separations between stones allow water infiltration. The water that seeps under the stones causes the ground to give away. Before you know it, your pavers are shifting downhill or becoming un-level. Imagine dips and divots all over your once level pavement. In addition to not looking great, these issues present a safety hazard for your guests to walk over.


What We Do
Residential and Commercial Gutter Services Available
Looking for gutters for your home? Let Gutter Masters give you a free estimate. We do it all from start to finish, we even have maintenance plans to keep you worry free.
Why get gutters?
The main purpose of a rain gutter is to protect a building’s foundation by channeling water away from its base. The gutter also helps to reduce erosion, prevents leaks in basements and crawlspaces, protects painted or stained surfaces by reducing exposure to water, and provides a means to collect rainwater for later use.
Gutters are also very effective at keeping building egress areas clear of falling water. Going into a house entrance below water running straight off the roof in a heavy down pour is like taking a shower. This major reduction in moisture also helps to keep entrance surfaces dry and free of moss, slime, algae and other growths likely to cause slips.
Our gutters are available in copper or in a large variety aluminum colors to match the character of your home.
Water collected by a rain gutter is fed, usually via a downspout or “down-pipe” (traditionally called a leader or conductor), from the roof edge to the base of the building where it is either discharged or collected. Water from rain gutters may be collected in a rain barrel or a cistern.
Need commercial gutters? We specialize in multi-family construction gutter systems. Let Gutter Masters come out for a free estimate. We even have service plans so you never have to worry about maintenance.
Clogged gutters can cause water leakage into the building as the water backs up. Clogged gutters can also lead to stagnant water build up which allows mosquitoes to breed and allows grasses and weeds to grow in the gutter.
Let Gutter Masters keep your assets protected with a no-hassle maintenance plan. We will take care of it all so you don’t have to.
Gutters must be maintained regularly to remove leaves and other debris to keep them from clogging. Gutters that are filled with debris can overflow and soak the foundation, damage the roof structure, and exacerbate ice dams in cold climates.
Low maintenance gutter guards, or screens, that assist in minimizing debris in gutter but allow water to enter are a good alternative to regular cleaning.
Gutter protection devices include:
- snap-in metal and plastic gutter guards
- filtered gutter guards
- stainless steel gutter guards
- hinged gutter guards
- metal total gutter covers
- gutter brushes
Regardless of the gutter guard protection used, all gutter systems should be examined for cleaning and repair twice every year.

TerniEnergia and Appalti Tecnologie Progettazione Ambienti & Costruzioni (Atp) have established the JV Purify, owner of a set of plants for the treatment of industrial fluid waste and reclamation of groundwater.
Purify manages operationally the hydraulic system called “Barriera”, consisting of 48 wells for the extraction of treated water, the monitoring system consisting of 95 piezometers placed to control the groundwater of the industrial site of Nera Montoro, chemical-physical and biological plants, for a total treatment of 50m3/h, according to a contract with Syndial SpA (Eni Group) and in compliance with the operational remediation plan.
Purify has started the worksite to upgrade its water and liquid waste treatment plants in line with the requirements of the Nera Montoro groundwater reclamation project.
The new liquid waste treatment plant with a capacity of 58,000 t/year includes two process lines:
- a biological treatment with activated sludge for the removal of nitrites, nitrates and ammoniacal nitrogen, and
- a physical chemical treatment, using a stripping tower (4 cubic metres/hour) with two three stage vacuum evaporators (2,500 litre/hour), for the purification of metals and arsenic.
The objective for the new plant is to intercept flows of liquid waste currently destined for plants located outside Central Italy, increasing the territorial competitive capacity, plant equipment and sustainability assessment of the purification activities, while at the same time reducing the transport of these materials and favouring their treatment and recycling.

a.传统的加热工艺Traditional heating processing
锅炉供汽电厂蒸汽 Boiler supplied power plant steam
热 压 机Heat compressor
水 池Water pool
从上面的生产工艺我们可以看出: 锅炉出来的蒸汽经压机后就直接排进了水池, 形成了能源的大量浪费。尤其在保温、保压以后, 需要降温的时候, 压机模板内蒸汽和热水被排进水池, 经常会看到热气冲天的现象, 表面上看排掉的是蒸汽和热水, 实际上排掉的就是能源和金钱。We can understand from above that the steam from boiler passes compressor and straightly enters into water pool which causes large energy waste. Especially, as cooling after temperature and pressure insulating, the steam and hot water in compressor would be discharged into water pool. We always see the phenomenon of volcanic steam. Apparently, we have discharged the steam and hot water, but in fact we have wasted the energy and money.
过热水生产工艺也是用蒸汽加热(没有蒸汽锅炉的,使用导热油加热的需通过热交换器将水温升到需要的温度.), 用蒸汽将高温塔内的水加热到压板需要的温度(最高180℃)形成过热水, 通过循环水泵将过热水打进压机, 压机出来的水(约120℃)回进高温塔, 通过蒸汽加热后继续供压机使用, 从而节约了大量的热能。冷却的时候, 将中温塔的水打进压机, 出来的热水(约120℃)通过循环水泵打进中温塔, 当冷却水的温度低于80℃时被排进水池。需要重新升温时, 用中温塔的热水将压机模板内的冷水置换出来, 同时将整个压机升温到80-90℃, 再用高温塔内的过热水将压机升温至需要的温度。具体流程图示意如下: The manufacturing processing of overheating water device adopts steam to heat(if steam boiler is not available, heat transfer oil and heat exchanger is necessary). Steam would heat the water in high temperature to the necessary temperature (max. of 180℃) to form hot water which would be pumped into compressor through circulating pump. The water flowing from compressor (about 120℃) would go back to high temperature tower and be used for compressor after heated by steam, which would save large sum of energy. As cooling, pump the water in medium temperature tower into compressor, then the hot water (about 120℃) would be pumped into medium temperature tower by circulating pump. And the water would be drained into water pool as its temperature goes below 80℃. If it is necessary to raise the temperature again, it need to use the hot water in medium temperature tower to exchange the cool water in compressor, meanwhile, to raise the temperature of compressor to 80-90℃ and to the necessary temperature using the hot water in high temperature tower. The principle illustration is as following:
C. 过热水装置的加热工艺与传统的加热工艺的区别Difference between the traditional heating processing and overheating water device heating processing
⑴.升温阶段 Phase of temperature rising
①传统的生产工艺是使用蒸汽将压机模板内的冷水置换出来, 然后再将压机系统升温至设定的温度, 使用的全部是蒸汽的能量, 因此能耗很高。而升温后从压机出来的蒸汽和热水直接排进了冷水池, 形成的是开放式的加热系统模式, 造成了热能大量的浪费。 Traditionally, the steam is used to replace the cold water in compressor, then rise the compressor temperature to setting value. All the energy is from steam and cause large consumption. The steam and hot water from compressor after temperature raised are directly discharged into cold water pool, which is open heating system mode and causes large sum of waste.
②压机的温度很不均匀(上面的温度高, 下面的温度低, 因为水在下面, 上面全部是蒸汽。)采用过热水装置升温则不同, 升温的初始阶段, 先用中温塔的热水将压机模板内冷水置换出来, 同时可将整个压机系统温度预热到85～90℃, 这部分的热量就不需要由蒸汽来提供, 从而节约了能源。当整个系统温度到了85～90℃后, 再用高温塔的过热水来升温整个系统, 压机出来的热水经过循环水泵又回进了高温塔, 形成了 一个封闭系统, 从而节约了大量的能源。同时, 由于过热水是用循环泵供水, 压机上面和下面的全部是水, 而且压力相等, 温度也相等, 不存在温差的问题, 生产出来的产品比原来的要好得多。The temperature of compressor is not average (upper part is high and lower part is low; steam gathering on upper part). It would have a different result to adopt overheating water device. At first phase, it need to use the hot water in medium temperature tower to replace the cold water in compressor, meanwhile, pre-heat the compressor to 85-90℃. In this way, such part of heat would not be provided by steam, so the energy is saved. As the system temperature reaches 85～90℃, it could use the hot water in high temperature tower to heat the whole system. The hot water would return to high temperature tower through circulating pump. Such process is a closed system, so it would save large sum of energy. Meanwhile, the overheating water is supplied by circulating pump. The water is full of compressor, the pressure is same and the temperature is same too. So we can gain the high quality product.
③过热水采用的是分段升温, 现将压机从25℃升温到80-90℃, 然后再升温到140℃左右。用蒸汽升温则不同, 将160℃的蒸汽直接通进压机, 温差很大。随着升温时间的加长, 压力会降低, 蒸汽温度也会下降, 热源会产生波动。过热水是采用恒温供热, 不存在上述问题, 所以生产出来的产品会更稳定。Overheating water adopts the method of progressive temperature rising. Raise the temperature of compressor to 80-90℃ from 25℃ firstly and then to 140℃. It is different to raise the temperature adopting steam. Input the steam of 160℃ directly to compressor which would cause the large temperature difference. As the long time of temperature rising, the pressure would reduce and steam temperature would reduce too, then heating source would fluctuate. On the contrary, overheating water adopts the method of constant heat supply. The above problem would not exist, so the manufactured products would be more stable.
⑵.降温阶段 Phase of temperature reducing
①传统的工艺在降温阶段是直接将冷却水通进压机, 将原来压机模板内的蒸汽和热水置换出来, 使整个压机的温度降低至设定的出板温度。所以我们在冷却水池边经常会看到有大量的蒸汽和热水喷进冷水池, 一幅热气腾腾的景象。其背后是大量的能源浪费, 实际上就是金钱的浪费。Traditionally, the cooling water would be directly input into compressor at cooling phase and the steam and hot water in compressor would be replaced. The temperature of compressor would reduces to setting value. Therefore, we could always see the steam and hot water flow into cold water pool, which is actually the waste of energy and money.
②使用过热水装置则大不同, 先用中温塔的热水将压机冷却到90℃, 出来的热水约100-140℃回进中温塔, 低于80℃的水则被排进了冷水池。从而节约的热能, 在水池边再也看不到热气腾腾的场面了。It would have the different result that use overheating water device. Cool the compressor to 90℃ by the hot water in medium temperature tower. The water of 100-140℃ would return to medium temperature tower and the water lower than 80℃ would be discharged into cold water pool. We would never see the phenomenon of volcanic steam and the energy is saved.
③由于过热水装置采用的是分段降温, 温差小, 生产出来的产品柔韧性很好, 不容易破碎, 成品率会更高。As overheating water adopts the method of progressive temperature reducing, the temperature difference is little. Therefore, the manufactured products are well flexible, not easy fragile and high acceptability rate.


The key to a successful project is to develop a cohesive plan as early as possible, freezing key design features of the port facility as early as possible. Design changes, especially those made well into the construction phase of a project, can cause significant increases in cost.
To minimise potential increases in cost in the later stages, it is essential that project developers do not “cut corners” in the early stages. A better specified design means lower tender prices from contractors and suppliers, and less opportunity for them to claim variations to the contract price. So $1 spent in the design stage can save up to $5 in additional costs in the construction phase, when making the same design change. It also avoids the embarrassment of cost and schedule overruns.
That is our basic ethos.
PED can take a concept and develop that into a defined project for which funding can be raised and regulatory authorizations and approvals can be obtained. But PED approaches projects on a phased basis allowing a client a series of “go/no go” decision points. But PED is equally experienced in undertaking discrete assignments as part of an overall project, such as merely undertaking the project management role, developing scopes of work for the major contract packages or undertaking environmental audits under ISO 14001.
Projects – From Concept to Operation
These phases can be defined as:
Project Inception and Pre-Feasibility Study Phase 1
- Feasibility Study and Front End Engineering Phase 2
- Detailed Engineering and Construction Phase 3
- Facility Operation, Training, Maintenance Phase 4
Project Inception and Pre-Feasibility Study (Phase 1)
Port developments can start with little more than an idea in someone’s head. PED can take that idea and, with its experience, produce an initial concept design of a facility. With its’ knowledge of shipping and shipping developments, the design will take into account the likely operational requirements (size and draught of ships, market demand, etc) over the full design life of the facility.
The design will also take into account the construction and maintenance costs of the facility, but at the same time allowing for possible expansion in the future.
Initial financial projections for the port and its operations will be made to verify that the facility would an economically viable proposition.
The work can also include a full market analysis to support the financial projections.
The deliverable will be formal report to the client which can then be used for:
- making the investment decision
- initial planning and other regulatory approvals
as well as being the control document for the next phase.
Feasibility Study and Front End Engineering (Phase 2)
PED has the capacity to undertake the formal feasibility study, and project manage specialist engineering companies who would undertake the
- front end engineering, cost estimate and project schedule
- surveying (soil and hydrographic)
- Environmental Impact Statement (“EIS”)
- detailed market appraisal, and
- legal investigations.
PED is also experienced in working with investment banks in order to raise the necessary funding for a facility, whether it is equity or debt that is required.
Clients can decide on how they wish this phase to be handled. PED has relationships with many companies and therefore can either put in a combined proposal for all this work, or can act merely as the client’s project manager. In the latter case, PED can prepare all the necessary documentation and manage every aspect required to prequalify, invite proposals/tenders, and ultimately award, those of these contracts that might be required.
It is during this phase that long lead time items should be identified, and initial work should be done in order to minimize any schedule effects on the overall project schedule, such as agreeing specifications with equipment suppliers and having formal quotations from them. There are key considerations of capital cost versus on-going operational and maintenance costs that must be decided upon at this stage. Often projects are driven by capital costs alone, which actually result in much higher full life costs.
It is during this phase that the contract strategy will be agreed for the detailed design and construction of the facility. The broad choice of contract strategies are:
- full turnkey construction under one single contract,
- project management with one or more “Engineering, Procurement and Construction” (“EPC”) contracts, or
- full Project Management and Engineering with multiple construction and supply contracts.
There are disadvantages and advantages of each approach, and therefore it is important to decide on the most appropriate for the particular project in question, but this has to be tied into the funding structure of the project.
The other critical element of this phase is securing the funding for the project. Funding can be found from a number of sources, be they strategic partners or funding institutions. Almost certainly, any funders will want to undertake “Due Diligence” on the project and PED is well versed in the skills required to manage such in-depth review of projects.
The completion of this phase is when the front end engineering design (“FEED”) is complete, all the necessary permitting is received and the funding is secured, and construction contacts signed.
Detailed Engineering and Construction (Phase 3)
PED can fulfil one of two roles during this phase of the project, either:
- as the owner’s management team, or
- by leading an independent project management team.
Depending on which contract strategy has been adopted will largely drive what the scope of PED’s work will be during this phase. At a minimum, PED would verify that all contracted parties were meeting their commitments in terms of specification, cost and schedule on behalf of the facility’s owner.
It is during this phase that PED will define the management systems to operate the port when complete, be they operational or financial. Modern state-of- the-art, but yet proven, systems are essential to the efficient operation of any container terminal.
It is during this phase that PED can start to recruit the key personnel that may be required for the operation and maintenance of the plant. In certain parts of the world it may not be easy to find suitable operatives to man the facility. PED can arrange for training to be provided either on site, at suppliers’ own premises or, in restricted numbers, on third party facilities.
PED has extensive contacts in the shipping world, and therefore can market the facility to the shipping lines and forwarding companies as well as to the providers of the inter-modal links, and, in the event that the facility is intended as a trans-shipment facility also, to the local but smaller terminals.
Facility Operation and Maintenance (Phase 4)
PED’s staff have operated a number of container and multi-cargo facilities and therefore could manage the operations and maintenance of a facility under a long term contract or until such time as a client has recruited their own management team.

Roof replacement is a large cost which requires professional aid and picking the top roofers to get it done. If it’s been over 8 years with the present roof or there has been damage to the roof, you need to begin budgeting for roof replacement costs. But without appropriate knowledge you may be lost attempting to discover the real costs of roof replacement. So essentially what are the costs which need to be considered while searching for replacing the roof? Is energy saving in your mind? It has been calculated that almost 35 percent of the heating and cooling costs are due to inadequate insulation in the roof. If you’re taking a look at long term roofing, different substances need to be properly used.
Some of the expert roofers say that as most cities and towns permit three layers of shingles, it’s bets to look at each layer for harm. Oftentimes, the harm is in the wood. While in some homes the entire roof needs to be replaced. It’s bets for your contractor to estimate the cost of debris removal in roof replacement costs. In case you have been advised complete roof replacement, get at least 3-5 estimates and never go with the lowest bid. It’s much better to go with the average bid and request references. Check the roofing firm at BBB to make sure professional work.
But if thicker shingles are needed, the cost doubles on the 20-year and 40-year shingles. Maple grove storm damage The typical cost of this roof includes roughly USD 4,500-5500 which includes only replacement of the whole roof of an average sized house. No repairs are included.
Metal roofs have become long lasting choices and are known to continue to approximately 70-80 years. To replace the whole metallic roof, without repairs costs about USD 10,000-15000 while the tar or rubber that is used on the flat roofs are offered at the cost of USD 2.5 per square foot. Even though they continue for more than 20 years, damage repair costs around USD 9.5 per square foot. It’s costly to get a complete roof replacement performed and generally with proper maintenance, you do not need it. But when the asphalt shingles have been over 8-10 years old, then it may need a tear-down and replacement. Whether there are any gutters, they need to be replaced which further adds to the cost of the roof replacement for offices and homes.
Before you sign on almost any roof contractor or roofing company, it’s best to ask your loved ones or friends for references. Speak to a couple roofers, get estimates and then decide what suits your budget. Normally the estimates will differ according to the company but not employ the cheapest bid because the quality may be cheap or has hidden costs.Home & Garden

This study examined the effects of hydrolyzing salts as coagulants in combination with Grewia spp. 4. Send us water facts for our Water Facts of the Week. DOMESTIC WATER REQUIREMENTS FOR URBAN AN... Module 3. Worldwide, a combination of coagulation, sedimentation and filtration is the most widely applied water treatment technology, and has been used since the early 20th century. (iii) Sedimentation aided with Coagulation (iv) Filtration (v) Disinfection (vi) Aeration (vii) Softening (viii) Miscellaneous treatments such as fluoridation, recarbonation, liming, desalination etc. The topic of coagulation is discussed at length in the next chapter. It should, however, be remembered that it is not complete process by itself.Â It simply assists plain sedimentation and it is to be followed by the process of filtration. The particular residuals depend on the coagulant that is used. Sedimentation is the separation from water, by gravitational settling, of suspended particles that are heavier than water. In water treatment plants, filtrationremoves a large number of contaminants, but still requires disinfection to produce drinking water that is safe. This is then followed by sedimentation (see Sedimentation Chapter). Â Â Â Â Â Â The sedimentation tanks are designed to give complete rest to the flowing water or water is allowed to flow at a very low velocity. Sedimentation of water can be plain or aided by coagulants. Module 2. The flocÂ should be allowed to move gently after initial quick mixing, The gentle movement of floc results in collision of particles and ultimately, the floc grows in size.Â The detention period of coagulated sedimentation tanks is about 3 to 4 hours. https://www.canada.ca/en/health-canada/services/environmental-workplace-health/water-quality/drinking-water.htmlWorld Health Organization. However, slow sand filtration systems require large areas of land to operate, because the flow rate of the water is between 0.1 and 0.3 metre per hour. In 1815, G.G. 4. The principle of sedimentation is based on . For more information about filtration in Nepal, including how rusty nails can remove arsenic from the water, see the Filters for Families fact sheet. Please feel free to contact us at any time at firstname.lastname@example.org or 1-306-934-0389 if you have any questions, suggestions, or comments. But it is difficult to cause the settlement of lighter particles.Â This phenomenon of settling down of particles at the bottom of sedimentation tank is known as. The dosage or quantity of coagulant should be carefully determined so as to cause visible floc.Â The quantity of coagulants should be such that turbidity of water is brought down to the limit of 10 to 25 p.p.m. 1996. For more information about the disinfection portion of the treatment process, see the Chlorination fact sheet. This lesson explains sedimentation aided with coagulation. Water Sanitation and Health: Coagulation, flocculation andclarification. Operation Water Drop looks at the chemical contaminants that are found in water; it is designed for a science class. Following six are the usual coagulants which are adopted for coagulation, Module 1. : The particle is moved in the horizontal direction by the velocity of flow. Operation Water Spirit presents a First Nations perspective of water and the surrounding issues; it is designed for Native Studies or Social Studies classes. 1996. The filters are generally cleaned twice per day with backwashing filters and are put back into operation immediately. The floc is subsequently removed in most cases by sedimentation. Â Â Â Â Â Â The sedimentation tanks are located near filter units and in case of variations in demand, they may even be called upto to work as storage reservoirs.

Thus, coagulation is merely a process by which impure water is prepared for successful purification by rapid sand filtration. Regina, Saskatchewan, Canada. IMPORTANCE OF SAFE WATER SUPPLY SYSTEM. The former impurities are removed from the bottom while the latter impurities are removed from the top. Submit Operation Water Drop Test Results/View Results, Ultrafiltration, Nanofiltration and Reverse Osmosis fact sheet, “Due diligence equals safe drinking water”, Watered Down Excuse, According to one scientist, high cost is no excuse for lack of safe drinking water in First Nations communities. These processes agglomerate suspended solids together into larger bodies so that physical filtration processes can more easily remove them. Â Â Â Â Â Â The source of water supply for the most of public water supply project is surface water.Â This water is turbid and contains many suspended impurities. With accurate dosages and proper application, the residuals of the added chemicals generally do not pose a problem. Coagulant aided sedimentation required to remove following impurities 1. Government of Canada. Finely divided colloidal matter and clay. The precipitate formed by TA-aided coagulation showed the advantage of releasing phosphorus faster than ferric phosphate, indicating the possibility of phosphorus recovery from wastewater as slow release fertilizer. 11 Flocculation and Dispersion of Colloidal Suspensions by Polymers and Surfactants: Experimental and Modeling Studies P. Somasundarana, Venkataramana Runkanaa,b, and P.C. 1996. Miscellaneous fragments of animal and vegetable matter 2. plankton mainly phytoplankton (microscopic plants). When the impurities are separated by natural process alone i.e. The ability of conventional treatment, such as sedimentation and sand filtration, is compared below with different types of membrane filtration, including microfiltration, ultrafiltration,nanofiltration and reverse osmosis. Lesson-12 Water treatment - sedimentation and coag... Module 5. Coagulation jar test in a water treatment plant. But it is difficult to cause the settlement of lighter particles.Â This phenomenon of settling down of particles at the bottom of sedimentation tank is known as hydraulic subsidence and every particle has its own hydraulic settling value which will cause its hydraulic subsidence. Operation Water Pollution focuses on how water pollution occurs and how it is cleaned up and has been designed for a Science and Social Studies collaboration. In fact, during rapid sand filtration, the water flows at a rate up to 20 metres per hour. Operation Water Flow looks at how water is used, where it comes from and how much it costs; it has lessons that are designed for Social Studies, Math, Biology, Chemistry and Science classes. Usually, the pathogens that are removed from the water are removed because they are attached to the dissolved substances that are removed by coagulation. particles. (2) Size and shape of particle : The force of gravity depends on the weight of particle and tends to move the particle in vertical direction. These chemicals are called coagulants, and have a positive charge. Particles with a diameter greater than 100 microns (or 0.1 millimetre), such as fine sand, are removed through sand filtration. It is estimated that plain sedimentation tank can remove about 60% of suspended matter and about 75% of bacterial load from water. The particle is thus given maximum opportunity to come down and settle at the bottom of tank. There are various different types of sedimentation: granular particles will each settle separately and will each be subject to a constant settling speed;; particles that are more or less flocculated will be of different sizes and, therefore, subject to variable sedimentation rates. Consequently, small particles will settle down very slowly. 3. Hence, the characteristics of water to be submitted to the coagulation plant should be properly studied before deciding the details of the plant. However, it is widely accepted that treatment facilities that use aluminum based coagulants often have higher levels of aluminum in their treated water, but not by much.

Addition of Grewia spp. Miscellaneous treatments such as fluoridation re carbonation, liming, desalination, etc SCREENING The process of removal of most of the big and visible objects, such as trees, branches, sticks, vegetations, fish, animal life etc present in â¦ Answer: sedimentation is the separation of a suspension of solid particles into a concentrated slurry and a supernatant liquid, either to concentrate the solid or to clarify the liquid while coagulation is the precipitation of suspended particles as they increase in size (by any of several physical or chemical. Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. The treatment of industrial wastewater or domestic sewage is commonly classified in three stages, which are first-stage treatment, second-stage treatment, and third-stage treatment. At low concentration levels, the settling speed increases as â¦ During treatment of water, sedimentation is done A. before filtration B. after filtration C. simultaneously with filtration D. along with chlorination. The colloidal and finely dispersed solids present in sewage are usually negatively charged and therefore do not agglomerate naturally into settleable mass. The diameter of a grain of fine sand is approximately 0.1 millimetre, so only particles with diameters less than 0.1 millimetre would pass through the fine sand layer. In a water treatment facility, the coagulant is added to the water and it is rapidly mixed, so that the coagulant is circulated throughout the water. INTRODUCTION TO DOMESTIC WASTEWATER TREA... Module 7. Drinking Water. The particle separation processes in sedimentation include the following: Coagulation, sedimentation, and flotation.

Coordinated Signal Control System in Urban Road Network
Keywords:coordinated traffic light control, intelligent transportation system, traffic light con-trol, wireless sensor network for smart mobility.
Road congestion has become one of the major problems of urban cities due to the growth in the number of vehicles and the limitation of road infrastructure. The consequences of this congestion can be seen through a difficult movement of vehicles, an increase in CO2 emissions, increasing energy consumption, and stress for drivers. Intelligent Transport Systems (ITS) based on wireless sensor networks (WSN) have emerged with new solutions and application potentials in the context of the Intelligent city. In this article, we study an approach of using a wireless sensor network to control the traffic lights of several intersections and optimize their performance by reducing the average waiting time of users. the proposed adaptive traffic light controller determines the traffic lights sequence in real time based on the current traffic situation at the local intersection, the expected arrivals and the degree of congestion at destination intersections. To evaluate our approach, we construct an intersection network of twenty-four intersections with high traffic intensity using the SUMO simulator, the results of the simulation demonstrate the efficiency and practicality of the proposed algorithm.

U.S. construction spending declined for a third straight month in June with spending on nonresidential construction falling by the biggest amount in six months. In June, construction spending dropped 0.6% after declines of 0.1% in May and 2.9% in April, reported by the Commerce Department on Monday. Nonresidential construction dropped 1.3 percent, the biggest drawback since December, while residential activity remained the same in June. Spending on government projects declined 0.6 percent, the fourth consecutive decline, with both federal and state and local construction activity down.
April through June construction weakened following posting firm gains in the winter. A number of analysts think warmer-than-normal winter weather caused builders to move up the start of projects, resulting in the second quarter to look feeble. Analysts anticipate construction will rally in the next coming months.
The weakness in construction in the spring was reflected in a disappointing report on overall growth in the second quarter, as measured by the gross domestic product. The GDP expanded at a modest annual rate of 1.2 percent in the April-June quarter with residential construction falling at an annual rate of 6.1 percent after six quarters of strong gains. In June, housing constructions remained the same with an gain in home renovation spending offsetting falls of 0.4% in single family construction and a fall of 1.5% in apartment building.
Nonresidential construction dropped 1.3% was led by a 4.5% drop in spending on construction in factory construction and a 1.6% decline in the area that includes shopping centers. The 0.6% decline in spending on government projects showed a 2.3% drop in spending at the federal level and a 0.5% fall in spending on construction projects by local and state governments. Overall construction spending fell to a seasonally adjusted annual rate of $1.13 trillion in June, a light 0.3 percent above the level in June 2015.

Offshore wind farms are a crucial component of the renewable energy landscape, but they face unique challenges due to their remote and harsh environments. Gearbox technology is undergoing innovations to enhance the efficiency, durability, and maintenance of wind turbines in offshore installations.
Harsh Conditions: Offshore wind turbines endure extreme weather conditions, including high winds, saltwater exposure, and temperature fluctuations. Gearbox designs must incorporate corrosion-resistant materials and advanced sealing mechanisms to withstand these challenges.
Maintenance Challenges: Accessing and maintaining offshore wind turbines is more challenging than onshore installations. Gearbox designs must prioritize reliability and longevity to minimize the need for frequent maintenance and repairs.
Direct-Drive Systems: Many offshore wind turbines are moving towards direct-drive systems, which eliminate the need for traditional gearboxes. These systems reduce maintenance requirements and potential failure points, improving the overall reliability of the turbine.
Condition Monitoring: Gearboxes in offshore wind farms often incorporate real-time monitoring systems that track performance and detect potential issues. This allows operators to plan maintenance more effectively and prevent costly breakdowns.
Innovative Lubrication: Lubrication systems in offshore wind turbine gearboxes are being designed to withstand the harsh marine environment. Advanced lubrication technologies help reduce wear and prolong the lifespan of gearbox components.
Floating Wind Turbines: Gearbox technology is also evolving to accommodate floating wind turbines, which are positioned on the open sea. These turbines require specialized gearboxes that can adapt to the movement of the platform while maintaining efficiency and reliability.
As offshore wind energy continues to grow, innovations in gearbox technology will be critical in ensuring the sustainability and effectiveness of offshore wind farms. Addressing the challenges of remote maintenance, harsh conditions, and reliability will be key to the success of these critical renewable energy installations.


Donald has participated in numerous family and multifamily projects as a yield planner, development consultant or landscape architect. This breadth of experience informs his decisions at all levels of design. He works to develop communities that are exciting and inviting places to live, work and play. Projects have ranged from mixed use developments in Florida to mountain side communities on the Sea-to-Sky Highway to cottage enclaves in Saskatchewan. Each project has brought its unique blend of challenges, opportunities and the satisfaction that comes from building a better place for people.
Highland Park, Calgary AB
Donald has experiencing in researching and compiling data from diverse sources and working in coordination with a consulting team to generate detailed opportunities and constraints mapping. This information is presented in a clear graphic format to act as the basis for land use decisions. Donald works to create the best fit between uses and site conditions while retaining programmatic integrity. He emphasizes the fiscal, environmental and practical importance of understanding site realities.
Highland Park, Calgary AB
Land use plans are based on a comprehensive understanding of site conditions and jurisdictional requirements. Plans also address issues of context and access. No decision is made in isolation. The objective is to create a development which is both functional and appropriate, suitable to the requirements of its residents and harmonious with its setting.
Donald crafts yield plans that reflect the findings of the site analysis and land use plan. These conceptual layouts refine the design intent into discrete parcels. Core areas and neighbourhoods are created. Linkages and buffers are established. Vehicular and pedestrian connections are defined. The yield plan anticipates not merely unit counts but also the shape of the community itself.
Pinnacle Ridge, Anmore BC
Yield plans evolve into site designs which incorporate the necessary additional information required to provide proof of concept. Sight designs are based on real world examples of applicable building and facility types. Conceptual grading, refined vehicular circulation and pedestrian corridors are also woven into the design. Entry monumentation, internal signage and key amenity features are located.
St. Augustine, Florida
The community is now fully envisioned and circumscribed by a set of principles that will guide detailed design. Building from this solid foundation will result in a functional and harmonious development meeting the needs of its residents and their guests.


Retaining Wall Construction
When are retaining walls required?
Retaining walls are built to retain soil on two different levels on either side of the wall.
They are often used in the construction of gardens, pools, some elevated patios and even driveways.
If you think your property is not sloping, get it measured by a landscaper to see if a retaining wall might be necessary.
Something important to note is that not all materials are suitable for all retaining walls.
Speak to your landscaper to design and plan a retaining wall that suits your property and the project you need done including the type of soil, how big the wall is, how much soil and materials will the wall be holding, the height and your budget.
Kinds of retaining walls:
Garden beds often require a retaining wall, however big or small.
These walls work to keep soil and the plants themselves organised and in their place and reduce the movement if there is heavy rain, like our summers in Bundaberg.
Sleeper Retaining Wall
can be either timber or concrete sleepers!
Concrete Retaining Wall
Concrete strikes again. asa very useful and versatile choice of material for your retaining wall. Because it is a synthetic material, there is a huge variety of choice with size, colour and texture and even weight of concrete bricks for your retaining wall.
Very durable and low maintenance. Concrete retaining walls will not require much repair when built correctly on a gravel base.
Poured concrete retaining walls are also an option! This could be a good idea if you are going for a sleek, modern look with a finish that is even and uniform.
Drainage systems need to be in place prior to pouring concrete.. once it is set, it is very difficult to change!
Timber Retaining Wall
Good old timber. Treated timber is used to build a strong and durable retaining wall.
The variation in timber can give a lot of variety to the aesthetic nature of the wall.
Although the sleepers are treated, they are not as durable as concrete or brick walls due to deterioration over time. However they still do last a long time!
You’ll need to make sure you don’t have termite around the house, get a pest inspection first as wood is susceptible to termite damage over time.
Timber retaining walls are probably the most cost effective.
Get Started on building the garden of your dreams
From gardens to pools, fences to driveways, we do it all.
Sandstone Retaining Wall
Sandstone is a beautiful material. You’ll be impressed by the finish event the most modest of sandstone retaining walls!
Durable (it is stone) therefore you’ll get a lot of years out of a sandstone retaining wall.
One of the more expensive materials to build a wall from, consider the size of your project, maybe sandstone is worth the extra investment for the look that you’re after.
Driveway Retaining Wall
Pool Retaining Wall
If you are considering building a pool in your yard, you’ll need to involve a landscaper to build a structure that can hold the weight of the earth on one side and the water on the other.
Interlocking concrete blocks are the most common material for retaining walls for pools.

Keep the roof valleys clean. A build-up of leaves and debris can create a natural dam. The back-up of water can result in roof leakage.
Attic vents and/or louvers are provided to properly ventilate the house. Please review them seasonally for correct operation.
Black streaks on your gutters are normal. These streaks are from weathering.
Check inside attic for signs of roof leaks. Be extremely careful not to damage or disturb electrical wiring or plumbing pipes that may be in the attic
Vents should remain unobstructed year-round. Your home has soffit vents and they should be cleared of debris. Also, check that these vents have not been stepped on and deformed. Excessive heat build-up in the attic is usually caused by blocked air vents. This condition can be resolved by clearing all obstructions away from the vents to allow proper heat release.
