DOW FILMTEC NF270-4040 Nanofiltration (NF) Membrane Elements for Commercial Systems

DOW FILMTEC NF270-4040 Elements are ideal for removing a high percentage of TOC and THM precursors with medium to high salt passage and medium hardness passage in commercial systems. The NF270 nanofiltration membrane is an ideal choice for surface water and ground water where good organic removal is desired with partial softening. DOW FILMTEC NF270-4040 elements have a fiberglass outer wrap.

DOW FILMTEC NF270-4040 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.
