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 listed as a compatible replacement for select DuPont FilmTec BW30-2540, GE/SUEZ AG2540TM, and LG Chem LG BW 2540 R membrane applications. Its nominal size is 2.5 × 40 inches. Confirm housing dimensions, connections, feedwater conditions, and operating requirements before ordering; nominal size alone does not establish compatibility.

How much water can the SpiroPure SP-BW2540 produce?

The SP-BW2540 has a rated average permeate flow of 750 GPD (±15%) at 225 PSI under test conditions using 2,000 ppm NaCl feedwater and 8% recovery. This is 2.5 times the published 300 GPD rating of the SpiroPure SP-BW2521 under those stated conditions. Actual output depends on feedwater temperature, salinity, pressure, and system conditions.

What does 99.5% salt rejection mean?

The published 99.5% salt rejection rating describes reduction of salt concentration under the stated NaCl test conditions. It is not a guaranteed removal percentage for every contaminant. Actual rejection varies with feedwater and operating conditions.

Is the SP-BW2540 suitable for seawater desalination?

No. The SP-BW2540 is a brackish-water membrane with a maximum recommended feedwater NaCl concentration below 10,000 ppm. For seawater applications, review the SpiroPure SP-SW2540 and confirm its specifications against your system and feedwater requirements. A membrane change alone does not make a brackish-water system suitable for seawater.

How much does the SpiroPure SP-BW2540 cost?
