WMC200 dNF80 NF module

Summary

Product identification

The WMC200 dNF is a hollow fiber nanofiltration membrane module designed for water and wastewater applications. It excels in removing color, turbidity, and dissolved organic molecules, including micropollutants such as pharmaceuticals, pesticides, and PFAS. The modules offer outstanding pH and chlorine resistance, require minimal pretreatment, no coagulation, 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

Membrane Characteristics

• **MWCO (Molecular Weight Cut-Off)**¹:
  • dNF80: 800 Dalton
  • dNF40: 400 Dalton
• Nominal MgSO₄ rejection²:
  • dNF80: 76%
  • dNF40: 91%
• Typical permeate flow range:
  • dNF80: 0.65-1.3 m³/h (2.9-5.7 gpm)
  • dNF40: 0.5-1.1 m³/h (2.2-4.9 gpm)

¹ MWCO is an estimation as it depends on size, shape, charge, and polarity of the compound being tested, as well as test conditions. Measured with PEG. ² Test conditions: 5.0 mMol/L MgSO₄, 3.0 bar, 20°C, v=0.5 m/s.
