Hoodi integrated wastewater treatment system is composed of five tanks, e.g, aeration tank, contact oxidation tank, MBR tank, disinfection tank, and sludge tank. These treatment systems have a balanced design in usability and aesthetics. They are quite adaptable to different site locations and ground conditions. There are two standard packaging types, underground bury type and above ground container type. The system can be further customized according to customer’s special need and request. Hoodi wastewater treatment systems are ideal for treating urban sewage water, rural village sewage water, and low contamination industrial wastewater. By careful design and optimization of the process parameters for growing bacteria and biochemical oxygen demand, the treated effluent water can reach Class A standard as defined in the National Standard GB18918-2002, Effluent Discharge Standard for Urban and Town Water Treatment Plants.
