MBBR technology uses thousands of polyethylene biofilm carriers working in mixed motion in a waste water treatment tank ventilated by a blower under PLC control. Each bio-carrier acts as a carrier bed to support the growth and proliferation of heterotrophic and autotrophic bacteria in the wastewater. This high-density bacterial population ensures high biodegradation within the system while also providing process reliability and ease of use. Moving Bed Bio-Reactor (MBBR) system, The system provides both BOD5 and nitrogen, phosphorus removal, can be applied in domestic and industrial wastewater treatment plants. Thanks to its flexible structure, it is a solution that provides cost advantage in new facilities. MBBR systems are compact, simple to use, require low maintenance, operate more efficiently and faster than other alternative methods.
