Organic Membrane Spiral Organic Membrane

Spiral organic membrane is produced through the combination of highly stable membranes
and advanced automated production processes. JIUWU HI-TECH has exploited whole series of spiral
organic membrane covering ultrafiltration, nanofiltration and reverse osmosis. These products have
been widely used in the process separation of pharmaceutical, food, chemical and other industries,
as well as the standard discharge, upgrading and reconstruction of discharge, reuse of reclaimed
water, zero discharge, and resource utilization.
