nanofiltration

General
Nanofiltration membrane technology is used to remove suspended solids, dissolved organic compounds, and multivalent ions from water. Nanofiltration membranes are typically thin-film composite (TFC) membranes, arranged as spiral-wound, tubular, or hollow fiber (capillary) modules based on polyamide or cellulose acetate.  

Cross-flow
The nanofiltration membrane process generally runs at pressures of 5 to 20 bar (72.5 to 290 pounds per square inch), depending on the specific application. 
A flow tangential to the nanofiltration membrane, known as cross-flow, is required in order to minimize fouling by the concentration polarization effects.

HFW1000
X-Flow nanofiltration membranes are characterized low operating pressure and chlorine resistant PES membrane materia. The membranes find their main applications in the removal of humic substances and other dissolved organic matter. And it also removes synthetic chemical compounds such as dyes. The mineral balance of the water is not affected.
