  • What is the PTFE-MBR membrane material?

    2022-09-20

    PTFE (Polytetrafluoroethylene, trade name "Teflon", commonly known as "King of Plastics") was discovered in 1932 by Dr. Roy Plunkett, who came to the United States after graduating from DuPont to work on organic fluorine. In the summer of 1938, he discovered the white powder polymer polytetrafluoroe Read More
  • Nf And Ro Membranes In The Material Separation Industry

    2022-09-15

    Membrane separation technology is a technology that uses the selectivity of the membrane (pore size) and the energy difference between the two sides of the membrane as the driving force to achieve separation due to the different mobility of the components in the solution through the membrane. As the Read More

  • Introduction to the structure of NF membranes and separation characteristics of commercial NF membranes

    2022-09-09

    NF membranes originated in the 1970s with the development of thin-layer composite RO membranes and in 1978, Cadotte et al. prepared the first thin-layer composite polyamide NF membrane using piperazine (PIP) and 1,3,5-homophthaloyl chloride (TMC). It has been widely used in water and wastewater trea Read More
  • What is the difference between MBR flat membranes compared to hollow fibre membranes?

    2022-09-06

    Compared to hollow fibre membranes, mbr flat membranes are more advantageous because they have better resistance to pollution and generally do not break, and the cleaning cycle is longer than that of hollow fibre membranes, and most importantly, the cost is lower. Advantages of flat sheet membranes Read More

  • How Do You Chemically Soak Clean An Mbr?

    2022-08-15

    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
  • Mbr Design Points

    2022-08-11

    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.

  • Classification Of Mbr Components

    2022-08-08

    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..

  • Classification And Basis Of Membranes For Mbr Processes

    2022-08-05

    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

  • Areas Of Application For Mbr

    2022-08-01

    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
