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

Ⅰ. 서론
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

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.

History and Development of the Activated Sludge Process
- The activated sludge process presently represents the most widespread technology for wastewater purification.
- The invention of the activated sludge process is connected with the efforts of British and American engineers at the end of the last century to intensify biological purification in fixed-film systems.

Nowadays, ‘eutrophication’ presents as one of the most serious ecological problems of open water sources such as lakes, oceans and reservoirs. It can be occurs naturally over centuries as lakes age and filled in with sediments, or acid rain. However, it has been rapidly increasing caused by human activities like fertilizers, municipal sewage, and wastewater from the factory. The Baltic Sea is
