Detailed explanation-1: -The activated sludge process is an aerobic suspended growth treatment system in which microorganisms use the organic content of wastewater as an energy source and for survival and replication.
Detailed explanation-2: -Wastewater treatment processes in which the microorganisms and bacteria treating the wastes are suspended in the wastewater being treated. The wastes flow around and through the suspended growths. The various modes of the activated sludge process make use of suspended growth reactors.
Detailed explanation-3: -Activated sludge process: The wastewater containing organic matter is aerated in an aeration basin in which microorganisms metabolize the suspended and soluble organic matter. Part of organic matter is synthesized into new cells and part is oxidized to CO2 and water to derive energy. It is an aerobic process.
Detailed explanation-4: -The activated sludge process is a means of treating both municipal and industrial wastewater. 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.
