  • Hollow-Fiber Polyethersulfone Nanofiltration

Welkin Industrial’s innovative hollow-fiber nanofiltration membrane, “NanoPure™,” is a world-leading nanofiltration membrane featuring a hollow-fiber structure and a surface with selectively charged functional groups. It can selectively remove harmful impurities such as heavy metals, divalent ions like calcium and magnesium, and organic chemicals from water while retaining certain low-valence ions.


NanoPure™ Product Line 
NanoPure™ is composed of modified polyethersulfone (PES) hollow-fiber membranes, offering exceptional stability and durability with high flux:


NanoPure™ Application Areas 
· Cross-flow, inward-outward filtration, and backwashable operation modes; 
· Vertical installation operating conditions; 
· High pH resistance and chlorine resistance; 
· Effectively removes pigments, divalent ions, and dissolved organic matter.
