DuPont FilmTec BW30-400/34 Short Brackish Water RO Membrane Element

The DuPont FilmTec BW30-400/34 is a high-rejection Brackish Water Reverse Osmosis (RO) membrane element designed for applications where vessel space is restricted. While carrying the BW30-400 designation, the $/34$ suffix indicates a specialized 34-inch length ("stubby" element) rather than the standard 40 inches. This shorter length provides flexibility for specific system designs or retrofitting vessels that require shorter elements at the end of a series.

Utilizing FilmTec's advanced polyamide thin-film composite chemistry, the BW30-400/34 delivers superior performance, achieving a high nominal salt rejection of 99.5% for brackish water sources. The element maintains high productivity, offering a nominal permeate flow of 10,000 GPD, making it a powerful solution for commercial and industrial water treatment despite its reduced size.
