FAQs on 4040 Industrial RO Membrane
What is a SpiroPure SP-XL4040 RO membrane?
The SpiroPure SP-XL4040 is an Extremely Low-Pressure ELP 4040 industrial reverse osmosis membrane element measuring 4" x 40". It performs RO filtration at roughly half the operating pressure of a traditional industrial RO membrane, reducing energy consumption for low-salt and low-TDS applications.
What is the use of a SpiroPure SP-XL4040 low pressure RO membrane?
The SP-XL4040 is used in industrial and commercial systems treating low-salinity water sources where reducing energy costs matters, such as production of purified water, boiler feed water, and food or beverage processing applications requiring consistent, energy-efficient output.
What is the flow rate of the SpiroPure SP-XL4040 membrane?
The SpiroPure SP-XL4040 produces an average permeate output of 2,400 GPD (±15%) at 100 PSI, tested against 500 ppm feedwater NaCl. Its low operating pressure requirement helps keep energy costs down relative to standard industrial membranes. The SP-UL4040 is the next step in low pressure applications, tested at 150 psi and 1,500 ppm for 99.4% rejection.
Is the SP-XL4040 suitable for low TDS water?
Yes. The SP-XL4040 is specifically designed for low salt and TDS applications, with a maximum recommended NaCl of 2,000 ppm. For higher-salinity brackish sources, a standard or brackish water rated membrane like the SP-BW4040 is a better fit.
Which models are compatible with the SpiroPure SP-XL4040?
The SpiroPure SP-XL4040 is manufactured as a compatible replacement for the Dupont Dow Filmtec XLE-4040 extra low energy membrane as well as Hydranautics Nitto ESPA4-4040, Hydronix Hydron HLE-4040, LG Chem LG BW 4040 UES, and Toray TMH10A, matching their 4" x 40" extremely low-pressure specifications.
How much does the SpiroPure SP-XL4040 cost?
The SpiroPure SP-XL4040 is priced well below comparable OEM extremely low-pressure elements for equivalent 2,400 GPD performance. See current pricing on this page, since compatible replacements typically cost a fraction of brand-name equivalents.
