NF(Nano filtration) Series Nano Filtration Membrane

  • Selective filtration – retains beneficial monovalent ions (Na⁺, K⁺, Ca²⁺, Mg²⁺)

  •  High removal of organics, bacteria, viruses & multivalent ions (MgSO₄ rejection ≥96%)

  •  No chemicals or heating required, preserves natural taste & bioactivity

  •  Adjustable NaCl rejection (40–95%) for tailored water composition

  •  Ideal for food & beverage, pharmaceuticals, bioengineering, and drinking water

  •  High flow up to 12,000 GPD (~45.5 m³/day)

Description

NF(Nano filtration) Series Nano Filtration Membrane

Product characteristics:

NF(Nano filtration) series is developed to remove waterborne organics, microorganism, bacteria,virus and most divalent and polyvalent ions and retain part of sodium, potassium, calcium and magnesium ions. There’s no chemical reaction during the separation process of NF filtration, no need to heat and won’t destroy bioactivity and change taste and flavour, therefore, it is widely used in drinking water industry, food & beverage industry, pharmaceutical industry, bioengineering and contamination control,etc.

1)  The stated performance is initial data taken after 30 minutes of operation based on the following conditions:

1500 ppm NaCl(MgSO4), 70 psi (5.0 bar) 25℃, pH 7.5, 15% recovery.

2)  Permeate flow rate for individual elements may vary with tolerance within 15%.
