Surface AerationBack to Services
The effluent from anaerobic reactor enter into Extended Aeration Tank. In EAT microorganisms degrade soluble organics aerobically. In order to ensure required population of bacteria in EAT, a requisite mixed liquor suspended solids (MLSS) is maintained. To maintain requisite MLSS and food to microorganism’s ratio (F/M), part of the settled sludge from secondary clarifier will be recirculated back to the extended aeration tank. An aeration system consisting of surface aerators shall be used to provide oxygen to bacteria.
