Decolorization NF with 34mil runner for high-color feed liquid, efficiently intercept natural pigment, caramel & organic chromogens, allow beneficial monovalent ions to pass through, retain active nutrients during decolorization.
Nanofiltration operates at comparatively low pressure with limited energy consumption, delivering an economical solution for water softening, organic substance removal and partial desalination within hygienic production environments.
High pigment-rejection modified polyamide layer achieves over 95% decolorization efficiency. Sanitary mesh eliminates residue dead zones to prevent pigment cross-contamination after CIP cleaning.
34 mil wide flow channels are resistant to clogging by pigment colloids and fit high-color, high-viscosity raw feed. It withstands high-concentration organic cleaners for complete breakdown of membrane surface pigment deposits.

About Us
In Integrated Solutions
Centered on hygienic membrane separation solutions, our factory prioritizes the R&D and mass production of sanitary spiral NF membrane. A complete set of laboratory testing equipment is deployed to inspect flux, rejection rate and chemical tolerance of every batch of membranes before delivery.
Our products feature excellent resistance to common cleaning agents and maintain steady filtration efficiency under long-cycle continuous operation. Beyond membrane element supply, our technical team can offer on-site process guidance, helping overseas clients optimize existing nanofiltration systems and cut energy consumption.
