FAQs on 8040 Industrial RO Membrane

What is an SP-BW8040 brackish water membrane used for?

The SP-BW8040 is an 8-inch × 40-inch brackish water RO membrane for compatible commercial and industrial water treatment systems. Suitability depends on feedwater composition, pretreatment and system design.

What is the price of an SP-BW8040 brackish water membrane?

See the current price and purchase options on this page. For larger quantities or commercial purchasing questions, contact AllFilters.

What are the specifications of the SpiroPure SP-BW8040 membrane?

Published specifications include 99.5% salt rejection and an average permeate flow of 10,500 GPD ±15% at 225 PSI, using 2,000 ppm NaCl feedwater at 15% recovery. Maximum recommended feedwater NaCl is below 10,000 ppm; maximum operating pressure is 600 PSI. Actual performance depends on feedwater and operating conditions.

Is the BW 8040 membrane suitable for all industrial RO systems?

No. Confirm membrane dimensions, pressure-vessel fit, feedwater composition, pretreatment and operating requirements. SpiroPure lists maximum recommended feedwater NaCl below 10,000 ppm. The SP-BW8040 is a brackish water membrane, not a seawater desalination element.

What is the difference between a 4040 and 8040 RO membrane?

A nominal 4040 element measures 4 inches × 40 inches; an 8040 measures 8 inches × 40 inches. SpiroPure lists 2,400 GPD ±15% for SP-BW4040 and 10,500 GPD ±15% for SP-BW8040, both at 225 PSI, 2,000 ppm NaCl and 15% recovery. They require appropriately sized pressure vessels. Actual output depends on operating conditions.
