Product Introduction

The G series high-pressure salt separation nanofiltration membrane elements are separation membrane products with high selective permeability to dissolved inorganic salts. They have high monovalent ion permeability and high divalent ion and COD rejection rates, and can efficiently separate valuable substances in raw water according to the Donnan effect and ion radius. The membrane elements are all prepared with high-pressure resistant membrane materials, with strong anti-fouling performance of the membrane sheets, making them more suitable for special fields such as zero-discharge nanofiltration salt separation and high-pressure special separation.

Product Features

  • High Selective Separation: Extremely high divalent ion rejection rate and monovalent ion permeability;
  • Strong Anti-Fouling Performance: "Surface modification technology" processing of the membrane sheet makes the functional layer more uniform and smoother, with high anti-fouling performance;
  • Uniform and Stable Performance: Fully automatic rolling technology ensures product performance consistency and stability.
