The Dow FILMTEC SW30-2540 Sea Water Membrane is specifically designed for applications where the higher TDS (Total Dissolved Solids) of marine water is addressed by the a thin film composite which sustains the higher pressures typically utilized in sea water reverse osmosis applications while maintaining a 99.4 percent stabilized salt rejection.
Specifications:

• Up to 700 Gallon Per Day production
• Up to 1000 psig
• Fits Standard 2.5" Housings or Pressure Vessels
• Highest flow rates available to meet the water demands of both sea-based and land-based desalinators
• May also be operated at lower pressure to reduce pump size, cost and operating expenses
• Improved FILMTEC seawater membrane combined with automated, precision element fabrication result in the most consistent product performance available

Filmtec RO membranes are currently transitioning from wet-packed to dry-packed packaging. While we will make every effort to ship two membranes with the same packaging, due to depleting inventory during this transition, it is possible you may receive one of each type.
