Description

FilmTec BW30HRLE-440i RO Membrane Element for Ultrapure Water

The FilmTec™ BW30HRLE-440i Elements are ideal for reverse osmosis plant managers and operators dealing with controlled pre-treatment waters and seeking advanced membrane treatment with good water purity and low energy consumption.

Uses

Industrial water demineralization

Advantages

Offers good salt rejection with 33% lower pressures
Delivers excellent silica, boron, nitrate, IPA and ammonium rejection
Provides increased active area with the most effective cleaning performance, robustness and durability due to its widest cleaning pH range (1 – 13) and chemical tolerance and the support of Dupont technical representatives
Includes iLEC™ interlocking end caps, reducing system operating costs and the risk of o-ring leaks that can cause poor water quality
