WRC200 dNF80 NF module

Summary

WRC200 dNF is a hollow fiber nanofiltration membrane module designed for water and wastewater applications. It is suitable for treating ground and surface water, as well as industrial and municipal wastewater reuse. The modules are effective in removing color, turbidity, and dissolved organic molecules, including micropollutants such as pharmaceuticals, pesticides, and PFAS. They offer excellent pH and chlorine resistance, require minimal pretreatment without coagulation, and produce no sludge.

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

Storage Information

New modules in original packaging can be stored for a maximum of 1 year from the shipping date. They should be kept in a dry place, protected from sunlight or any heat source, at temperatures between 1 and 40°C (33 and 104°F). The ex-factory storage solution consists of 84wt% water, 15wt% glycerin, and 1wt% sodium metabisulfite.
