NF98 series nanofiltration membrane elements adopt Proshare® proprietary multi-layer composite membrane. Nano-level and ultra-thin hydrophilic coating technology endows excellent anti-fouling ability.These membranes deliver twice the flux of traditional TFC membranes and operate at least 50% lower pressure, making them a superior replacement for NF270, XC-N, DL, DK, and other traditional TFC membranes.
n NF98 membrane surface is super hydrophilic, with excellent anti-fouling performance and long service life;
n NF98 membrane flux is generally 30% higher than traditional TFC, and some models even have up to 2 times the flux, resulting in significant energy reduction;
n High rejection rate of divalent salts >98% (sulfate, iron, heavy metals, etc.), and allows monovalent salts to pass through;
n High Removal of Organic Compounds such as pesticides, herbicides, antibiotics, and THM precursors, etc.
