Effectiveness Of Bod Removal From Domestic Sewage In Constructed Wetland Using Pilot Scale Study

Domestic sewage is wastewater generated by human activity in residential, commercial, institutional, and industrial settings in which the domestic wastewater is segregated from the industrial wastewater. Domestic sewage concentrations for pollutants may vary according to the different sources of gen...
