The basic purpose of the primary treatment system is to remove total suspended solids, oil and grease, and some specific pollutants. The basic purpose of the secondary biological treatment system is to remove the organic load from the effluent. The basic purpose of a tertiary treatment system is...

the required effluent quality (including potential future restrictions); and costs and availability of land. As previously indicated, treatment methods can be classified as pretreatment/primary treatment;secondary treatment;tertiary treatment;sludgetreatment/stabilization; and ultimate disposition of residuals. ...
Preliminary wastewater treatment precedes primary treatment. Its main function is to minimize operational problems and to protect subsequent treatment units. The major processes that are used during the preliminary wastewater treatment process are Equalization, Neutralization, Temperature adjustment, Screening, ...
Bacterial communities in wastewater treatment plants (WWTPs) affect plant functionality through their role in the removal of pollutants from wastewater. Bacterial communities vary extensively based on plant operating conditions and influent characteristi
Step Two : Primary Sewage Treatment This is another settlement stage which involves separation of solid macrobiotic matter from wastewater. The process is simply done by pouring wastewater into the big tanks so that the solid matter can settle on the surface of the tank. ...
The traditional municipal wastewater treatment process includes three stages: primary, secondary, and advanced. Buoyant and non-buoyant materials are separated in primary treatment using physical or chemical methods. Dissolved organics and colloidal materials are removed during secondary treatment by ...
Preliminary treatment: screening and pumping Primary treatment: next, the wastewater enters primary settling tanks where the flow of water slows down Secondary treatment: aeration and final settling Disinfection Sludge treatment Waste-to-energy View chapterExplore book ...
Two primary wastewater treatment plants near Vancouver, B. C., include facilities for chlorination, comminution, preaeration, grit removal, sedimentation, and sludge digestion. In the smaller plant, infiltration in tributary sewers was a problem, as was acceptance of septic tank contents into the pl...
