Evoqua's ADI® MBR is an activated sludge treatment system that improves treatment performance and consistency compared to conventional activated sludge systems by using a physical membrane barrier for liquid-solids separation instead of traditional gravity clarification. This technology complements our anaerobic technologies​ by aerobically polishing anaerobically pretreated wastewater, and can also be used as a stand-alone process.The MBR can treat wastewater from a wide variety of industries. The MBR system’s long solids retention time and physical membranes work together to provide more consistent removal of organics, ammonia, and nitrogen than conventional activated sludge systems. The biochemical oxygen demand (BOD) and total suspended solids (TSS) concentrations discharged from the process are negligible, and very low effluent phosphorus concentrations can also be reached.
