FILMTEC™ BW30HR-440i

The FILMTEC™ BW30HR-440i element is a high-performing, high productivity element combining the highest active membrane area in the industry with the maximum rejection brackish water reverse osmosis (RO) membrane. It incorporates Dow's newest, proprietary BW30HR membrane sheet technology, designed to deliver the highest quality RO permeate. This is combined with the cleanability of a 28 mil feed spacer, to minimize capital expenses in high-purity industrial water applications, without increasing operating flux.
