Product Description

NF membranes have a molecular weight cut-off between 150-2000 Dalton usually. RisingSun Membrane manufacture spiral sanitary, Net-Wrapped NF membrane elements for food process, such as dairy, for simultaneous concentration and partial (monovalent ion) demineralization, Biotec, Pharma, and other applications.

RisingSun Membrane Nanofiltration cross replace Dupont / DOW/ Filmtec NF membrane.

We offer different dimensions, such as 3838/3840/ 6338/8038/8040/8338 etc. Full-Fit NF Membrane Elements. 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 design feature leads to excellent hydrodynamics in combination with low energy demand.

Demineralization and concentration
NF separates a range of minerals from a liquid, allowing only the fluid and certain monovalent ions to pass through the membrane.

The membrane has a minimum rejection of 98% on 2,000 ppm MgSO₄ at 25°C (77°F) and 110psi operating pressure.
The Dairy Processing Elements are typically used in food related processes requiring stringent sanitary procedures. Applications include lactose desalting, deacidification and demineralization of whey or UF permeate.
