FAQs on 8040 Industrial RO Membrane
What is an 8040 ultra low pressure RO membrane?
An 8040 ultra low pressure RO membrane is a high-capacity reverse osmosis element that operates at reduced pressure to lower energy costs. The SpiroPure SP-UL8040 measures 8" x 40" and performs RO filtration at roughly two-thirds the pressure of a traditional industrial RO membrane.
Where can the SpiroPure SP-UL8040 membrane be used?
The SP-UL8040 is suitable for low salt-content surface water, groundwater, tap water, and municipal water sources. It's commonly used in small and medium commercial pure water systems where reducing energy consumption matters as much as output capacity. The ultra low pressure models sit in a middle ground between the XL extra low pressure and brackish water membranes for tested pressure and feedwater NaCl.
What is the flow rate of the SP-UL8040 membrane?
The SpiroPure SP-UL8040 produces an average permeate output of 10,500 GPD (±15%) at 150 PSI, with a 15% fresh water recovery rate, tested against 1,500 ppm feedwater NaCl.
Is the ULP 8040 membrane suitable for brackish water?
Yes, within limits. The SP-UL8040 is rated for feedwater up to 5,000 ppm NaCl maximum, covering low to moderate brackish water conditions. For higher-salinity brackish sources up to 10,000 ppm, a standard brackish water membrane like the SP-BW8040 is a better fit.
Which membranes can the SP-UL8040 replace?
The SpiroPure SP-UL8040 is manufactured as a compatible replacement for the Dupont Filmtec ECO PRO-400, Hydranautics Nitto ESPA1/ESPA2, Hydronix Hydron HLP-8040, LG Chem LG BW 400 ES, and Toray TMG20D-400, matching their 8" x 40" ultra low-pressure specifications.
How much does the SpiroPure SP-UL8040 cost?
The SpiroPure SP-UL8040 is priced around $515, comparable to other 8040 industrial elements, delivering ultra low-pressure performance without the premium of a brand-name OEM part. See this page for current pricing.
