1. General Introduction
FilmTec BW30-400 IG Element is a 8 inch industry grade membrane for high Rejection Brackish Water reverse osmosis process. BW30-400 IG high rejection brackish water reverse osmosis (RO) element is designed for use in industrial water treatment applications. It maintains the same flow and rejection performance of the BW30-400 elements, but does not carry the ANSI standard 61 or KIWA certifications, offering a more cost effective option for industrial applications.BW30-400 IG elements may be cleaned over a wide pH range (pH 1-13), BW30-400 IG is a drop-in replacement for the BW30-400 in systems that do not require drinking water certifications.
