TLC Memb, 2-1/2x40, 900 GPD @ 150 PSI

The Toray RE2540-BLN is a 2-1/2" x 40" thin-film composite reverse osmosis membrane element rated for 900 GPD at 150 PSI, engineered for commercial RO systems that demand consistent performance and high-quality permeate. Toray Membranes USA is recognized worldwide for precision membrane manufacturing, and this TLC element brings that reliability to light commercial water-purification platforms where steady output and strong contaminant rejection are essential. This makes it a practical, drop-in choice for operators who want to standardize on a proven element across multiple housings and sites.

This standard 2540-format element fits the common 2.5-inch RO housings used in point-of-use, small-system, and modular commercial designs. Through semipermeable membrane technology, it rejects a broad spectrum of dissolved solids, salts, and other contaminants, producing clean product water for drinking, food service, laboratory, and process applications. The 900 gallon-per-day rating provides ample output for many small commercial setups while remaining easy to scale by adding elements and housings as demand grows.

• Toray thin-film composite RO membrane element
• 2-1/2" diameter x 40" length (2540 format)
• Rated 900 GPD at 150 PSI test conditions
• Fits standard 2.5" RO pressure vessels
• Strong dissolved-solids rejection for purified water
• Lightweight element at approximately 3 lbs

To protect the membrane and preserve flux, always pretreat feed water with adequate sediment and carbon filtration to remove chlorine, which can permanently damage the thin-film layer and void membrane performance. Maintaining the recommended feed pressure, temperature, and recovery rate will extend element life and keep rejection rates high over many months of service. Operators should also monitor permeate flow and quality so a gradual decline can flag the right time for cleaning or replacement before output suffers. As a direct, dependable replacement element, the Toray RE2540-BLN keeps commercial RO systems running at peak purity, delivering the consistent, high-quality water that drinking-water and process applications rely on day after day.

Stocking a spare element is wise for any commercial RO operation, since membrane life ultimately depends on feed-water quality and how diligently pretreatment is maintained. With sound pretreatment and routine monitoring, the Toray RE2540-BLN provides dependable, long-lasting service as a core component of small commercial purification systems. Trusted by water professionals, the Toray name stands behind every element for confident, repeatable performance.
