Overview of topic
Sewage is municipal wastewater that has a high number of organic materials. Sewage is therefore cleaned in sewage treatment facilities (STPs) by heterotrophic bacteria before discharge to make it less polluting.
The treatment of sewage is done in two stages.
Primary treatment – The physical removal of large and tiny particles is the focus of these treatment steps. Floating debris is removed first by sequential filtering, followed by grit removal by sedimentation.
Secondary treatment, also known as biological treatment, involves passing the primary effluent through enormous aeration tanks where it is constantly agitated, allowing for the rapid growth of beneficial aerobic bacteria into flocs. Flocs are bacterial masses that are bound together by fungal filaments to form mesh-like structures. The bacteria reduce the BOD (biochemical oxygen demand), which is the amount of oxygen required to oxidize total organic matter in the effluent, while they are developing. The BOD test assesses the rate at which microorganisms absorb oxygen; the higher the BOD of wastewater, the greater its polluting potential. The effluent is then directed to a settling tank, where the bacterial ‘flocs’ are allowed to settle, resulting in activated sludge.
