Sprial Membrane Elements

  • Reverse osmosis membrane elements

    Reverse osmosis membrane elements

    Reverse osmosis membrane is the core component of reverse osmosis. It is a kind of artificial simulated biological semi permeable membrane with certain characteristics. It can intercept substances greater than 0.0001 microns. It is a very fine membrane separation product. It can effectively intercept all dissolved salts and organic substances with molecular weight greater than 100, and allow water to pass through. 

  • Ultrafiltration Membrane elements

    Ultrafiltration Membrane elements

    Ultrafiltration membrane is a kind of microporous filter membrane with pore size specification and rated pore size range of less than 0.01 micron. The target products with different molecular weights can be separated to achieve the purpose of decolorization, impurity removal and product classification.

  • Microfiltration membrane

    Microfiltration membrane

    Microfiltration membrane generally refers to the filter membrane with a filter aperture of 0.1-1 micron. Microfiltration membrane can intercept particles between 0.1-1 micron. Microfiltration membrane allows macromolecules and dissolved solids (inorganic salts) to pass through, but will intercept suspended solids, bacteria, macromolecular colloids and other substances. 

  • Nanofiltration Membrane elements

    Nanofiltration Membrane elements

    The MWCO Range of nanofiltration membrane is between reverse osmosis membrane and ultrafiltration membrane, about 200-800 Dalton.

    Interception characteristics: divalent and multivalent anions are preferentially intercepted, and the interception rate of monovalent ions is related to the concentration and composition of feed solution. Nanofiltration is generally used to remove organic matter and pigment in surface water, hardness in groundwater and partially remove dissolved salt. It is used for material extraction and concentration in food and biomedical production.
