RisingSun NF membrane introduction


1. Product introduction: Nanofiltration membrane molecular weight cutoff between the reverse osmosis membrane and ultrafiltration membrane, about 200-800 Dalton. Trap retention characteristics: preferential retention of divalent and multivalent anions, monovalent ion rejection rate of the liquid concentration and composition related. Nanofiltration is generally used to remove organic matter and pigments in surface water, groundwater hardness and partial removal of dissolved salts, for the extraction and concentration of substances in food and biomedical production. Nanofiltration operating pressure is generally 3.5-30bar.


2. Nanofiltration membrane material: polyamide, sulfonated polyether sulfone, sulfonated polysulfone.


3. Advantages: high thermal stability and chemical stability

   Imported raw materials to ensure high quality

   Membrane module replacement is simple

   A variety of membrane components available for selection

   Film core packing density, unit membrane area low cost

   No dead ends design, not easy to pollution


4. Applications: Clarification of fermentation broth in pharmaceuticals and bioengineering

   Clarification of biochemical lysates

   Removal of suspended matter

   MBR Sewage Treatment

   RO / NF pretreatment


RisingSun membrane provides a variety of fine molecular weight cut-off nanofiltration membrane components, its compact structure, the surface area / volume ratio is reasonable. Through the use of different flow network, (13-120mil) can change the width of the liquid flow path to adapt to a variety of viscosity of the liquid. In order to meet the application of some special industries, we can provide acid, high temperature, anti-pollution film products.
