The DOW FILMTEC SW30-4040 reverse osmosis membrane has one of the highest flow rates available to meet the water demands of sea-based and land-based watermakers. The FilmTec Reverse Osmosis Membrane can also be operated at lower pressure to reduce pump size, operating expenses, and overall cost. These reverse osmosis membranes are commonly used in on-board watermakers to create drinking water from brackish or ocean water for boats, yachts and cruise ships.
