DOW Filmtec TW30-4040 RO Membrane 2400 GPD, a 4″ x 40″ Reverse Osmosis Membrane that can provide RO quality water up to 2400 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 features the thickest feed spacer(34 mil) available in the industry today to lessen the impact of fouling. This offers the highest quality water for small and mid-size commercial systems purifying less than 10 gallon per minute(2300 L/h) of RO water and is the industry standard for reliable operation and production of the highest quality water in commercial applications.
Filmtec RO elements 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 TW30 Tap Water Thin Film-Commercial RO membranes are tape-wrapped—-built with the same high quality membranes and materials of construction as industrial elements, except for the hard outer shell, and are more economical for commercial systems with one or two elements per housing. In addition to the highest quality water and the lowest energy costs, DOW membranes also deliver savings through its increased resistance to fouling by providing the industry’s longest lasting and most reliable performance.
This membrane is a part of the “Tape-Wrapped 4040 Elements for Commercial Applications” by DOW FILMTEC and are applied in commercial water treatment systems, food service, hospitality industry, medical and research institutions. Its advanced technological design is manufactured for excellent structural stability and more productivity than other elements.
