Activated Sludge Process
The activated sludge process is a biological wastewater treatment process that uses aeration and a biological floc composed of bacteria and protozoa to break down organic pollutants in wastewater.
The process involves three main steps:
- Aeration: Air or oxygen is introduced into a mixture of wastewater and microorganisms, which allows the microorganisms to grow and multiply.
- Settling: The microorganisms and other solids settle out of the wastewater, forming a sludge.
- Recycle: A portion of the sludge is recycled back to the aeration tank to maintain the population of microorganisms.
The activated sludge process is a highly efficient method for removing organic pollutants from wastewater. It is also relatively low cost and can be used to treat a wide range of wastewater types. However, the process does require a large amount of space and can be sensitive to changes in wastewater quality.
