  • DOW Filmtec SW30HRLE-4040 RO Membrane 1600 GPD

  • DOW Filmtec SW30HRLE-4040 Seawater Reverse Osmosis Membrane, a 4.0" x 40" RO membrane element that can provide RO quality water of up to 1,600 gallons per day at an 8% recovery rate. It can operate at feed pressures ranging from 800 psi to 1,200 psi with 99.75% salt rejection. This Seawater RO element is ideal for use in medium-sized desalination systems that produce less than approximately 10 GPM (2300 L/h) of permeate. SW30HRLE-4040 reverse osmosis element is a 4-inch diameter version of SW30HRLE-400, the industry’s leading seawater element which offers an unprecedented combination of high salt rejection and productivity to enable the lowest total cost of purifying high salinity water. This reliable performance is the result of improved membrane combined with automated, precision element fabrication.

  • The SW30 Elements have one of the highest flow rates available to meet the water demands of both sea-based and land-based desalinators. SW30 elements may also be operated at lower pressure to reduce pump size, cost, and operating expenses. Dow’s fully automated and precise element production enables the most consistent products in the industry for the most consistent product performance available. SW30HRLE-4040 may be used as a pilot element to demonstrate performance for the design of larger systems. This product is best for seawater desalination and marine(yacht) applications.

    Key Features and Benefits:

     

    • 1,600 gallons per day.
    • 1,200 psi max operating pressure.
    • SW30 elements provide longer life due to high cleanability.
    • High Salt rejection for high quality permeate.
    • High flux reduces energy used and pressure required.
