WMC110 dNF80 Union NF module

Summary

Product Identification & Membrane Characteristics

The WMC110 dNF modules are hollow fiber nanofiltration membranes designed for water and wastewater treatment, including ground and surface water, as well as industrial and municipal wastewater reuse. They are effective in removing color, turbidity, dissolved organic molecules (including micropollutants like pharmaceuticals, pesticides, and PFAS). The modules offer high pH and chlorine resistance, require minimal pretreatment, and produce no sludge.

Two types of dNF membranes are available: dNF40 and dNF80, offering different flux and rejection characteristics.

• Membrane material: Modified PES
• Membrane charge: Negative @ pH=7
• Membrane fiber inner diameter: 0.7 mm
• Filtration mode: Inside-Out; Vertical
• Operation mode: Cross-flow
