The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.

2021年6月17日 · The activated sludge process is a multi-chamber reactor unit that uses highly concentrated microorganisms to degrade organics and remove nutrients from wastewater, producing quality effluent. The goal is to maintain aerobic conditions and to keep the activated sludge suspended.

Activated sludge treatment can define as the wastewater treatment plant, which eliminates the particulate matter like sand, unwanted inorganic and organic wastes and harmful microorganisms from the sewage waste. The process is followed by …

The activated sludge process consists of maintaining an active floc in a tank supplied with oxygen so that maximum contact is made between the incoming waste water and the microorganisms in the floc. In the conventional process, a rectangular tank is usually used and the waste water is introduced into a concentration of microorganisms ...

At its core, the activated sludge process is a method of treating sewage and industrial wastewater using highly concentrated microbial communities. The process involves introducing air or oxygen to a mixture of wastewater and activated sludge, which is a slurry of microorganisms capable of digesting organic matter.

2022年12月6日 · Activated Sludge process offers efficient and effective removal of BOD, COD and nutrients when designed professionally and operated properly. The process itself has flexibility and numerous modifications can be tailored to meet specific requirements (e.g. for nitrogen removal).

Why are activated sludge process characteristics and control important? Normal variations based on design, population served, and daily patterns. Increased TSS/ VSS can lead to issues such as bulking and foaming, reduced oxygen transfer, and decrease in overall treatment efficiency.

Description of the Activated Sludge Process. The activated sludge process is very widely used for biological wastewater treatment. The figure below shows a general flow diagram with the typical components present in an activated sludge wastewater treatment plant.
