    Description Specification Optional items



     Imported high quality film roll, imported brand film ideal substitute   
         
    ● Roll type microfiltration membrane, roll type ultrafiltration membrane, roll type nanofiltration membrane, roll type reverse osmosis    membrane

    ● Membrane retention channel, mesh, membrane materials custom made, personalized needs






    Roll type microfiltration membrane element    MF


     Entrapment particles:0.1~1 μm
    ● Applied to cut off suspended solids, bacteria and macromolecular colloidal substances
    Operating pressure:0.3~7 bar
     It can customize membrane products of acid and alkali resistance, anti-pollution, high
       temperature resistance








     Roll type ultrafiltration membrane element    UF

     Molecular Weight Cut-Off:1KD~200KD
    It can retain macromolecular substances (proteins, pigments,
       polysaccharides)
       
    Small molecules (inorganic salts, small molecule pigments,
       monosaccharides, ash) can also be retained
    Alternative activated carbon decolorization, resin impurity removal,
       crystal extraction, etc.
    It can be customized to resist acid and alkali, anti - pollution and
       
    high temperature film products.




     


       
     Roll type nanofiltration membrane element  
         NF


    ● Molecular Weight Cut-Off:200D~800D
     Characteristics: Preferential retention of divalent and polyvalent
       anions, and rejection rate of monovalent ions related to the
       concentration and composition of the feed solution

     Removal of organics and pigments in surface water, hardness in
       groundwater and partial removal of dissolved salts
       
     Material: polyamide, sulfonated polyether sulfone and sulfonated
        polysulfone. It can customize film products of acid and
        alkali 
    resistance, anti-pollution, high temperature resistance. 




     


       
     
    Roll type reverse osmosis membrane element       RO


     ● Interception of molecular particles:greater than 0.0001 μm, isocratic
        water molecules passing

     ● We provide a unique polyamide composite membrane.
     It can produce standard pressure, low pressure, ultra low pressure and
        seawater desalination roll type reverse osmosis membrane element.

      Material: polyamide, sulfonated polyether sulfone and sulfonated
        polysulfone. It can customize film products of acid and alkali
        resistance, anti-pollution, high temperature resistance.
