Introduction
MBR technics is a perfect integration by membrane separation technology and normal biological treatment. Instead traditional secondary sedimentation tank, sand filter tank by capillary hollow fiber UF membrane, and the effluent water quality can match reclaimed water reuse or Reverse Osmosis input water standard. MBR system is very suitable for high discharge standard water treatment plant and old plant upgrades, transformation.




MBR Self-Operated Volute Ultrafiltration with High Intensity for Backwash (BN90) is a new-type water treatment technology, integrated with membrane separation unit and biological treatment unit. Membrane modules are used instead of secondary sedimentation tank in the bioreactor to maintain high activated sludge concentration and reduce the land area of wastewater treatment facility and the sludge amount through maintaining low sludge load. The MBR membrane can completely block and retain the microorganisms in the bioreactor through its filtration function, which achieves the complete separation between the hydraulic retention time and activated sludge age, thus avoiding the sludge expansion problem of conventional activated sludge process. Compared with conventional biological water treatment technology, MBR Self-Operated Volute Ultrafiltration with High Intensity for Backwash (BN90) has the following main characteristics including high treatment efficiency, good outlet water quality, compact equipment layout, small footprint, easy automatic control and easy operation management.

System flow scheme
MBR Self-Operated Volute Ultrafiltration with High Intensity for Backwash (BN90) allows for size reduction of the structures required by up to 70 % and even increase the performance of wastewater treatment plants.



Membrane Modules

The principle of membrane filtration in MBR Self-Operated Volute Ultrafiltration with High Intensity for Backwash (BN90) is based upon the separation of solids suspended in a watery solution by means of a pressure difference. While the water permeates through the membrane, the solids, bacteria and even most viruses are retained on the concentrate side on the membrane surface where they are removed by relative movement. The MBR sewage treatment plant is provided with multiple membrane elements in an integrated membrane module in 2 or 3 stages in an aerobic tank. The MBR Self-Operated Volute Ultrafiltration with High Intensity for Backwash (BN90) utilizes side-stream cross-flow membrane configuration. The wastewater is filtrated using suction filtration, and the filtered water becomes treated. Air is supplied from the air diffuser installed on the bottom of the membrane module to prevent sludge from adhering to the membrane surface. Thus, the system can perform stable treatment
