Huamo HM280-82 Nanofiltration Membrane, 82(7.6) ft2(m2), Huamo (CAT#: STEM-GMAE-4833-LGZ)

Huamo 280 series nanofiltration membrane has ultra-high flux, can remove TOC and THM (trihalide) precursors, and has certain selectivity to divalent salts with medium pass rate and other salts with high pass rate . It is an ideal membrane element for removing organic matter in surface water and groundwater, softening, concentrating, separating or purifying inorganic salts, organic matter, natural medicine and fermentation broth. The NF 280-400/34 element has a large active area and high permeate flux, providing industry with a wide range of water treatment, concentration and separation applications. It is suitable for the removal of TOC, THM precursors, salts, low operating energy consumption systems under ultra-low pressure, as well as material separation, municipal and industrial water treatment.
