Effluent treatment plants are treatment plants, where industrial effluents and waste waters are treated .It mainly involves removal of acrylic polymers using a dissolved air floation and removal of acrylic monomers using aerobic degradation. Preliminary treatment is done to remove large debris and grit. The primary effluent is cloudy and gray. It mainly consists of phosphorus and ammonia. The primary effluent is sprayed over the hungry bugs dissolved food and chemicals. However these bugs cannot be removed. The other chemicals that can be removed are EDTA, resin, fatty acids, and chloroform. The tertiary treatment plants include nitrogen removal system using bacterial nitrification, air stripping or ion exchange. The treated sewage water can be used for agricultural purpose. The gases emitted during the process are used in industries.
