MBR(Membrane bioreactor) is a world-recognized advanced wastewater treatment technology. The flat film technology produced by our company has the patent of independent MBR multi-layer flat film, which has the advantages of good water quality, strong impact ability, easy maintenance, high filtration accuracy, small footprint, long life and so on. The flat membrane produced by the company is composed of a filter membrane, a flow guide cloth and a honeycomb plate. The top of the flow guide plate is provided with a suction port. The activated sludge membrane in the pool is blocked outside the membrane element, and the filtered water is sucked out by the membrane element under negative pressure. The flat membrane can be applied to sewage in various industries, providing a wide range of flat MBR formwork technologies to solve various water treatment industries.
