Environment Water and Wastewater Product Number : NF90-400/34iWater Membrane
1. Low energy usage reduces power consumption and costs 2. Durable with good cleanability for long element life 3. Thicker feed spacer delivers better tolerance of suspended solids and enables more efficient cleaning of organic material from the element 4. FilmTec Performance and quality
The DOW FILMTEC NF90-400/34i nanofiltration element is a high area, high productivity element designed to remove a high percentage of salts, nitrates, iron, and organic compounds such as pesticides, herbicides, and THM precursors. The high active membrane area combined with the low net driving pressure of the membrane allows the removal of these compounds at low operating pressures. It uses a 34 mil feed spacer to lessen the impact of fouling on pressure drop across a vessel and enhance cleaning effectiveness. The iLEC™ interlocking end caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.
