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.

In the field of wastewater treatment and water reuse, MBR, also known as Membrane Bio-Reactor, is a new type of water treatment technology that combines membrane separation units with biological treatment units. According to the structure of the membrane can be divided into flat membrane, tubular membrane and hollow fibre membrane, etc., according to the membrane pore size can be divided into ultrafiltration membrane, microfiltration membrane, nanofiltration membrane, reverse osmosis membrane, etc..

Membranes can be prepared from a wide range of materials and can be liquid, solid or even gas phase. The majority of separation membranes used are solid phase membranes. Depending on the pore size, they can be divided into microfiltration, ultrafiltration, nanofiltration and reverse osmosis membranes; depending on the material, they can be divided into inorganic and organic membranes, with the inorganic membranes being mainly microfiltration grade membranes. The membranes can be homogeneous or non-homogeneous and can be charged or electrically neutral. Membranes widely used in wastewater treatment are mainly solid phase asymmetric membranes prepared from organic polymeric materials. Read More
