Filmtec Membrane bw30-4040
DOW Filmtec BW30-4040 RO Membrane 2400 GPD
DOW Filmtec BW30-4040 RO Membrane 2400 GPD, a 4″ x 40″ brackish water Reverse Osmosis Membrane that can provide RO quality water up to 2,400 gallons per day at a 15% recovery rate. It can operate at feed pressures ranging from 225 psi to 600 psi with 99.5% salt rejection. This element offers the highest quality water for a medium-sized water treatment system that produces less than approximately 10 GPM (2300 L/h) of permeate. This membrane element features the thickest feed spacer available in the industry today to lessen the impact of fouling as well as a fiberglassed shells.
These RO elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability offering high rejection of dissolved solids and organics and operate very efficiently at lower pressures. The Thin Film-Commercial RO membranes have hard shell exterior and are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops. In addition to the highest quality water and the lowest energy costs, FILMTEC membranes also deliver savings by providing the industry’s longest lasting and most reliable performance due to increased resistance to fouling.
This membrane is a part of the “Fiberglass Elements for Light Industrial Systems” line of products by DOW FILMTEC and are applied in industrial water de-mineralization, production of municipal drinking water, and water reuse. Its advanced technological design is manufactured for excellent structural stability and more productivity than other elements.
