A new kind of plastic carrier elements to immobilize microorganisms and moving bed biofilm reactor(MBBR) has been developed. An aerobic MBBR was investigated for treating domestic wastewater . An anaerobic MBBR was tested to treat high strength organic synthetic wastewater and a combined anaerobic aerobic MBBRs system to treat food industry effluents. It was concluded that this process had high treatment efficiency, stable effluent qualitial, very compact reactor and easy operation.
