Activated sludge treatment

Vedclass · Answer

(C) The 'activated sludge system' is a biological wastewater treatment process. In this process,a portion of the sludge (which contains a high concentration of aerobic decomposer bacteria) is recycled back into the aeration tank. This recycled sludge acts as an inoculum,providing a large population of metabolizing bacteria,yeasts,molds,and protozoa to the incoming raw sewage. These microorganisms form flocculent masses called 'flocs' and oxidize the organic matter present in the sewage into $CO_2$ and water. Therefore,the process of recycling these bacteria is a defining characteristic of the activated sludge treatment.
