Vontron SW4040LE Seawater RO Membrane
Hi Flow Seawater Membrane, Vontron SW4040LE
4”x40” Sea Water Membrane
1,900 gpd / 99.7% / 800 PSI
Provides high productivity and high salt rejection.
SW sea water membranes provide optimum salt rejection and permeate flows. They are chosen when higher flow product water and lower feed pressures are needed.
Brief Introduction SW series of sea water aromatic polyamide RO element developed by VONTRON for seawater desalination. This series of elements have the characteristics of low operating pressure, low equipment investment, good desalination performance and stability. Among them, the SW8040XHR-400 have the highest desalination rate of 99.85%, which ensure that drinking water can be produced from seawater through one pass RO system.
Specified Performance*:
Salt Rejection: 99.7%.
Permeate Flow: 1,900 gpd (7.2 m³/day).
Membrane Area: 90 ft².
Diameter/Length: 4 inch / 40 inch.
Feed Spacer Thickness: 28 mil.
Test conditions: 32,000 mg/l NaCl, 55.2 bar (800 psi), 25 °C (77 °F), pH 8, recovery rate 8%.
*The Specified Performance is based on data taken after approximately 30 minutes of operation. Actual testing of elements may be done at conditions which vary from these exact values; in which case, the performance is normalized back to these standard conditions. Permeate flow for individual elements may vary +25 / -15 percent from the value specified.
Application:
Vonron SW4040LE is a standard size seawater membrane, widely used for watermakers, desalinators, seawater desalination systems, marine (yacht and boat), Navy and martime applications.
Commonly used in on-board Watermakers to create drinking water from seawater for yachts, boats, and cruise ships.
Made in China by Vontron
Equivalent to*:
Filmetc SW30-4040, GE Desal SE4040FF, Hydranautics SWC5-LD-4040, Hydranautics SWC1-4040 , Toray TM-810L , CSM RE4040-SHA.
