Sewage is generated from the residential area and some kind of industry. Their sewage is contain of high organic meters and some amount of other pollutants.
As I explain in the past blog1. Wastewater is one of the global environmental issues. It has to be treat before discharge into any water body like a lake, river, and sea.
Main objectives of sewage treatment plants are as follows:
1) to remove organic meters from the wastewater.
2) to reduce water parameters.
3) to neutralize wastewater before discharge.
4) to kill pathogens.
