SG-NF4-8040 NF Membrane Nano Filtration Membrane Dow Same Model Replace DOW NF245-390-FF, RisingSun Membrane Technology (CAT#: STEM-GMAE-3188-LGZ)

Stable rejection(%): 92.0 - 95.0
Flux rate (LMH): 50
Replacement reference: GE(DL)
Test condition: 2000ppm MgSO4, 110psi(0.76MPa), 25℃

Typically the molecular weight cutoff is between 150-2000 Daltons.
The operating pressure is around 3.5-30bar.
Our NF3 model has a high TOC rejection rate of 40~60% CaCl2 rejection and 15% recovery at 500ppm CaCl2, 70psi, 25°C. The rejection of MgSO4 was 97%.
Our membrane modules feature a compact design and optimal surface area to volume ratio. The height of the feed channel can vary (from 13 to 120 mils) depending on the thickness of the feed spacer material. This design feature results in excellent fluid dynamics combined with low energy requirements.
Standard size 2540/4040/8040, other sizes optional.
Membrane chemistry: polyamide, sulfonic acid polyether, sulfonic acid polyether.
Cross Reference: Koch, Hydranautics, Microdyn Nadir, GE, AMI…
