Mbr membrane contamination refers to the membrane filtration process, the water particles, colloidal particles or solute macromolecules due to physical and chemical interactions with the membrane or mechanical action caused by adsorption on the membrane surface or membrane pore, deposition caused by the filter pore size becomes smaller or blockage, resulting in membrane flux decay phenomenon. At this time it is necessary to carry out a clearing of the mbr membrane. Read More

The MBR membrane method is becoming more and more widely used and is attracting a lot of attention for its stable and clear effluent, but its huge maintenance volume is also causing many users headaches; so to minimise the intensity of maintenance work in use, the following issues need to be taken into account during the design phase.

Compared to many conventional biological water treatment processes, MBR has the following key advantages. Read More

Entering the mid to late 1990s, membrane - bioreactors have entered the practical application stage in foreign countries. The Canadian company Zenon first introduced the ultrafiltration tubular membrane - bioreactor and applied it to municipal wastewater treatment. In order to save energy, the company also developed the immersion hollow fibre membrane module, which has developed a membrane - bioreactor has been applied in the United States, Germany, France and Egypt and more than a dozen places, the scale from 380m3 /d to 7600m3 /d. Japan's Mitsubishi rayon company is also a well-known provider of immersion hollow fibre membrane in the world, its application in the MBR has also accumulated many years of experience, in Japan and other countries with a number of actual MBR projects. Kubota Japan is another company that is competitive in the practical application of membrane - bioreactors, producing plate membranes with high flow rates, resistance to contamination and simplicity of proces Read More
