Spiral Membrane Element Configuration:
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.We offer different dimensions, such as 3838/6338/8038/8040/8338 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.
