MP025-0300 dNF 40 NF module

Summary

Product Identification

The MP025-0300 dNF modules are hollow fiber nanofiltration membrane modules designed for lab-scale tests in water treatment and industrial and municipal wastewater reuse. These modules are effective at removing color, turbidity, and dissolved organic molecules, including micropollutants such as pharmaceuticals, pesticides, and PFAS. They feature outstanding pH and chlorine resistance, require minimal pretreatment, no coagulation, and produce no sludge.

Two types of dNF membranes, dNF40 and dNF80, are available, offering different flux and rejection characteristics to suit specific application requirements.
