WMC110 dNF80 Short Union NF module

Summary

Product identification

The WMC110 dNF Short modules are hollow fiber nanofiltration membrane modules designed for water and wastewater applications, including ground and surface water, industrial and municipal wastewater reuse. They are effective in removing color, turbidity, dissolved organic molecules (including micropollutants like pharmaceuticals, pesticides, and PFAS), and offer high pH and chlorine resistance. Minimal pretreatment and no coagulation are required, and they produce no sludge.

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

Membrane 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
