FAQs on 2540 Commercial RO Membrane
What is a 2540 brackish RO membrane used for?
A 2540 brackish RO membrane treats water with elevated dissolved solids in commercial settings requiring higher output than a 2521 size allows. The SpiroPure SP-BW2540 is well suited for small commercial applications with moderate salinity feed water.
Is the SP-BW2540 compatible with other 2540 RO membranes?
The SpiroPure SP-BW2540 is manufactured as a compatible replacement for the Dupont Filmtec BW30-2540, GE/Suez AG2540TM, and LG Chen LG BW 2540 R, matching their 2.5" x 40" size and brackish water performance specifications.
How much water can the SpiroPure SP-BW2540 produce?
In test conditions to verify output, the SpiroPure SP-BW2540 brackish water filter produces an average permeate flow rate of 750 GPD (±15%) at 225 PSI operating pressure, with an 8% fresh water recovery rate. That's roughly 2.5 times the output of the shorter 2521 brackish membrane at the same pressure.
What does 99.5% salt rejection mean?
A 99.5% salt rejection rate means the membrane blocks 99.5% of dissolved salts and similar contaminants from passing through, based on standardized lab testing against 2,000 ppm feedwater NaCl. Real-world rejection of brackish water RO membranes can vary with feed water quality and system conditions.
Is the SP-BW2540 suitable for seawater desalination?
No. The SP-BW2540 is rated for brackish water up to 10,000 ppm NaCl maximum, far below seawater's typical salinity. For seawater desalination, choose the SpiroPure SP-SW2540, engineered for up to 40,000 ppm NaCl at higher operating pressure.
How much does the SpiroPure SP-BW2540 cost?
The SpiroPure SP-BW2540 is priced as a cost-effective compatible alternative to OEM brackish water elements in the same 2.5" x 40" size, without sacrificing salt rejection performance. Check this page for current pricing and free shipping.
