Secondary treatment is greatly Employed in sewage treatment and is also applicable to lots of agricultural and industrial wastewaters.

Within the digestion tower, methane fuel is generated in four phases (hydrolysis, acidification, acetone gene and methanogene phase); it can be converted into electricity inside of a get more info block heating plant and may be used to provide the plant with Strength.
