SPIRAL-NF---SS-NF1-2540

SPIRAL-NF

NF membrane has a molecular weight cut-off between 200-800 Dalton usually. It is generally targeted to remove only divalent and larger ions. Monovalent ions such as sodium and chloride will pass through a nanofiltration membrane, therefore many of its uses involve groundwater softening, de-salting of the process stream. NF membrane is also becoming more widely used in food processing applications such as dairy, for simultaneous concentration and partial (monovalent ion) demineralisation. NF membrane operation press is around 3.5-30 bar.

We supply spiral NF membrane with a precise MWCO. They have a compact design and an optimum surface area to volume ratio. The feed channel height can be varied by the thickness of the feed spacer material (from 13 to 120 mil). This helps to adapt the viscosity or the solids content of the liquid. This design feature leads to excellent hydrodynamics in combination with low energy demand. To meet some specialty applications, acid/caustic resistant, fouling resistant or high temperature membrane products are available.

ADVANTAGES:

• Imported high quality raw material, high flux, chemical resistance
• MWCO is precise
• Sanitary design without dead
• Simple and economic module replacement
• Various choices of module dimensions
• High packing density
