Product Description

NF membranes have a molecular weight cut-off between 150-2000 Dalton usually. RisingSun Membrane manufacture spiral type membrane with glassfiber outer, which is the best choice for water treatment.
Our model NF3, which has high rejection of TOC, the rejection rate of CaCl₂ is 40~60% under 500ppm CaCl_2, 70psi, 25°C, 15% recovery.
The rejection rate of MgSO₄ is >97%.

We offer different dimensions, such as 1812/2520/2540/4040/8040 etc. Our membrane module has 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.

Main application:
NF membrane mainly used for groundwater hardness removal, surface water purification, organic matter purification and recovery, drug separation and concentration.
