INDUSTRIAL WASTE WATER BIOLOGICAL TREATMENT
Biological treatment is a generic term applied to processes that use microorganisms to decompose organic wastes either into water, carbon dioxide, and simple inorganic substances, such as aldehydes and acids. The purpose of biological waste treatment is to control either the environment for microorganisms so that their growth and activity are enhanced, and to provide a means for maintaining high concentrations of the microorganisms in contact with the wastes.
Biological treatment usually takes place in three stages:
Solids and sand filtration
The introduction of air into sewage so as to provide aerobic biochemical stabilization during a detention period and the removal of settleable solids.
Chemical treatment of the waste water.
