Environment Water and Wastewater Product Number : NF270-400/34iWater Membrane
Good organic (NOM) removal Partial softening preserves water character High flux results in high yields Low energy usage reduces power consumption and costs Durable with good cleanability for long element life Thicker feed spacer delivers better tolerance of suspended solids and enables more efficient cleaning of organic material from the element
The DOW FILMTEC NF270-400/34i element 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 and medium hardness passage. It is an ideal element for surface and groundwater 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. 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.
