General Electric Co. introduces membrane-based wastewater treatment technology, combining anaerobic digestion technology with its ZeeWeed* 500 membranes to create anaerobic membrane bioreactor (AnMBR). AnMBR offers lower costs, better performance and the ability to generate renewable energy from industrial wastewater.This technology is an ideal solution for industrial wastewater with high biochemical oxygen demand and chemical oxygen demand concentrations that result in higher aerobic treatment operational expenses. GE’s AnMBR provides reduced energy consumption, energy recovery and reduced sludge production both economically and reliably. Anaerobic digestion is a biological process in which microorganisms break down biodegradable material in the absence of oxygen. Advantages of anaerobic treatment include energy savings by not requiring oxygen, reduced sludge production and reduced footprint.
