Introduction of MBR membrane technology

MBR technology uses filters to submerge in aerobic biological treatment tanks. Wastewater is treated by biological sludge and this sludge is retained by membrane filtration. So improve the efficiency of removing suspended solids in treated water. The content of suspended sediment inside the biological tank will increase rapidly, causing the biodegradability of pollutants in the input wastewater. In addition, the treated wastewater also removes suspended residues and has high transparency.

Structure of MBR membrane is hollow fiber or flat sheet with membrane size of 0.1-0.4µm, membrane only for clean water to pass through, suspended solids, colloid, bacteria, some viruses and large organic molecules ... will be retained on the membrane surface. Clean water follows the pipe to escape through the suction pump system. In addition, air blowers will supply continuous gas, to provide air for the microbiological system to operate and create pressure on the membrane fibers to blow out the sludge that adheres to the membrane, ensuring that the membrane will not be choked throughout. operation process.
