wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to ha
Activated sludge is a term used both to refer to a widely utilized wastewater treatment process, and to the solid com-pounds which result from that process.
The activated sludge technique is one of the most commonly used methods for handling human waste in municipal settings around the world, and it can also be employed in the treatment of industrial wastewater.

in an aerobic aquatic environment.
Purpose: to remove settleable organics and floating scum (grease and oils).
Efficiencies:
Suspended solids 50 – 65%
BOD 30 – 35%
Primary clarifiers are either circular or rectangular. They are very similar to sedimentation basins used in water treatment except that scum removal is always provided in addition to sludge collection.

2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m

산업폐수 중 처리하기 어려운 폐수로 섬유, 피혁, 도금폐수 등을 들 수 있으며, 이 중 특히 배출 폐수량은 적으나 고농도이면서 난분해성 물질을 함유하고 있어 고도의 처리기술이 필요한 폐수가 색소를 함유한 폐수이다. 또한 하천에 방류될 경우 확산성이 매우 강하여 일광을 흡수하고 하천
