## Overview

The Dow Filmtec SW30-2540 is a polyamide thin-film composite seawater reverse osmosis membrane designed for maximum flow rates and consistent performance. Engineered with automated precision fabrication, it supports high productivity with excellent salt rejection, operates efficiently at lower pressures to reduce costs, and tolerates free chlorine levels below 0.1 ppm. Ideal for both land and sea-based desalination systems, it withstands temperatures up to 113°F and a broad pH range, ensuring reliable, long-lasting water purification.

## Description

Improved FILMTECTM seawater reverse osmosis elements offer the highest productivity while maintaining excellent salt rejection. FILMTEC SW30 membrane elements have the highest flow rates available to meet the water demands of both sea-based and land-based desalinators. FILMTEC SW30 elements 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. *Notes:Permeate flow and salt rejection based on the following test conditions: 32,000 ppm NaCl feed stream, pressure specified above, 77°FF (25°C), and 2% recovery. Permeate flows for individual membrane elements may vary +/-20%. Active area guaranteed +/- 3%.

## Questions & Answers

**Q: My membrane has a rubber o ring on both sides will this still work which side should I put the intake**
A: This particular Filmtex SW30 2540 membrane has one rubber o-ring at one end. This o- ring has to go on the upstream side of its housing unit.

**Q: Does it work in idromar mini compact?**
A: Yes, this membrane should work.  If you check page 4 of your product manual, you will see it listed under replacement parts.  That is this model.

**Q: What is the gph rating?  what is the pressure required for this membrane?  does it need a casing?**
A: stone age needs to go DOW form 609-00377-0811available on website which provides the information requested. (Gph is gallons per hour)  the form referenced previously indicates 700 gallon per day at 800 psig at 77 degrees F. A correctly designed casing is required. regards da vinci

**Q: Are the o-rings included?**
A: Should be !
