FILMTEC NF270-400

The FILMTEC™ NF270-400 elemant is a high area, high productivity element designed to remove a high percentage of TOC and THM precursors while having a medium to high salt passage; medium hardness passage.

The FILMTEC NF270-400 element is an ideal element for surface and ground water applications where good organic removal is desired with partial softening in order to maintain a minimum level of hardness for organoleptic properties and preservation of distribution networks.

The high active area membrane combined with low net driving pressure of the membrane allows the removal of these compounds at low operating pressure.
