Material Separation Nanofiltration MASP Series Membrane Elements
Detailed description
(1) Product Positioning
The MASP series membrane elements are nanofiltration membranes specifically developed for material separation and resource recovery, with key applications in the separation and concentration of liquid streams, zero‑liquid discharge from wastewater, and lithium extraction from salt lakes.
(2) Product Features
It exhibits high ion selectivity and a precisely defined molecular weight cut-off; the membrane’s separation layer has a high degree of crosslinking, providing excellent resistance to chemical cleaning.
(3) Product Performance
