Design Construction Maintenance of Water Treatment Plant
Design construction maintenance of water treatment plant

How do treatment plants protect our water?
Wastewater treatment plants: * Remove solids, everything from rags and plastics to sand and smaller particles found in wastewater; * Reduce organic matter and pollutants--naturally occurring helpful bacteria and other microorganisms consume organic matter in wastewater and are then separated from the water; and, * Restore oxygen--the treatment process ensures that the water put back into our rivers or lakes has enough oxygen to support life.
Where does wastewater come from? * Homes--human and household wastes from toilets, sinks, baths, dishwashers, garbage grinders, clothes washers and drains. * Industry, Schools, and Business--chemical and other wastes from factories, food-service operations, school activities, hospitals, shopping centers, etc. * Storm Water Infiltration and Inflow from Runoff and Groundwater--water that enters the sanitary sewer system during a storm, as well as groundwater that enters through cracks in sewers. The City of Columbia has one set of sewers for wastewater from homes and businesses (sanitary sewers) and a separate system for storm water runoff.

On the average, each person in the U.S. contributes 50-100 gallons of wastewater every day. If you include industrial and commercial water uses, the per person usage of water is as high as 150 gallons per day.
How does our wastewater treatment plant work?
The 16 million gallons per day (average) entering the facility is conveyed by over 635 miles of interceptor sewers, varying in size from 8 inches to 72 inches in diameter. The Sanitary Sewer Maintenance Section is responsible for the maintenance and repair of all public sewer mains and manholes.
The type of wastewater treatment used in the Columbia Regional Wastewater Treatment Plant is called the complete-mix activated sludge

    The District of Columbia Water and Sewer Authority receives and treats wastewater collected from the District of Columbia sewer system and from the Maryland and Virginia suburbs. The treatment has two phases, in the first phase begins as debris and grit which is removed and trucked to a landfill where the sewage then flows into primary sedimentation tanks that separate the solids from liquids. The second phase is where oxygen is bubbled into treatment tanks so microbes can break down organic matter. Then the microbes convert ammonia into harmless nitrogen gas. Residual solids are settled out and the water is…

    * Water treatment - describes those industrial-scale processes used to make water more acceptable for a desired end-use. These can include use for drinking water, industry, medical and many other uses. Such processes may be contrasted with small-scale water sterilization practiced by campers and other people in wilderness areas. The goal of all water treatment process is to remove existing contaminants in the water, or reduce the concentration of such contaminants so the water becomes fit for its desired end-use. One such use is returning water that has been used back into the natural environment without adverse ecological impact.…

    Sewage Treatment Plan

    • 676 Words
    • 3 Pages

    Sewage may include storm water runoff. Sewerage systems capable of handling storm water are known as combined sewer systems. This design was common when urban sewerage systems were first developed, in the late 19th and early 20th centuries.[3]:119 combined sewers require much larger and more expensive treatment facilities than sanitary sewers. Heavy volumes of storm runoff may overwhelm the sewage treatment system, causing a spill or overflow. Sanitary sewers are typically much smaller than combined sewers, and they are not designed to transport storm water. Backups of raw sewage can occur if excessive infiltration/inflow (dilution by storm water and/or groundwater) is allowed into a sanitary sewer system. Communities that have urbanized in the mid-20th century or later generally have built separate systems for sewage (sanitary sewers) and storm water, because precipitation causes widely varying flows, reducing sewage treatment plant efficiency.[4]…

    We all know that, despite the fact that water is highly treated for contaminants in municipal plants, by the time it reaches out home it can gather new contaminants due to the fact that most municipal and residential water pipes are made of lead and asbestos-cement. Moreover, there are also contaminants that are deliberately added in water, such as chlorine, which can causes numerous health problems in the long run. As such, the need for a whole house water filter is obvious. Despite the fact that it is not new on the market, CRYSTAL QUEST is not as popular as its competitors. This is a shame, because they have a very versatile range of products, which makes it easy for any customer to find a product as suitable as possible for their individual…

    As rainfall travels over roofs and the ground, it may pick up various contaminants including soil particles and other sediment, heavy metals, organic compounds, animal waste, and oil and grease. Some jurisdictions require stormwater to receive some level of treatment before being discharged directly into waterways. Examples of treatment processes used for stormwater include retention basins, wetlands, buried vaults with various kinds of media filters, and vortex separators (to remove coarse solids). Sanitary sewers are typically much smaller than storm sewers, and they are not designed to transport stormwater. In areas with basements, backups of raw sewage can occur if excessive stormwater is allowed into a…
