An Effluent Treatment System is a method of removing impurities from wastewater or sewage before it reaches natural water sources such as rivers, lakes, and oceans¹. It involves combining and treating wastewater from different operations in a series of water treatment facilities, such as primary, secondary, and biological units¹. Alternatively, it can also involve strategically splitting and mixing wastewater streams to avoid unnecessary dilution and to minimize the cost of treatment¹. Effluent Treatment System can use anaerobic and aerobic processes with chemical catalytic additives to treat wastewater³.
