Featuring precision automated fabrication and a durable polyamide thin-film composite design, it operates efficiently under high pressure and broad pH conditions, making it ideal for both land and sea-based desalination systems. ## 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%.

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 ! ## Frequently Bought Together - Dow Filmtec SW30-2540 Seawater Reverse Osmosis Membrane - KEZE Waterproof Food Grade Silicone Lubricant Plumbers Grease for Valve Sealant Faucet O Rings 1 oz 1-Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/66194781-sw30-2540-seawater-reverse-osmosis-membrane](https://www.desertcart.hr/products/66194781-sw30-2540-seawater-reverse-osmosis-membrane) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-13*
