FAQs on 8040 Industrial RO Membrane
What is an 8040 ultra low pressure RO membrane?
An 8040 ultra low pressure RO membrane is an industrial reverse osmosis element designed for operation at relatively low pressure. The SpiroPure SP-UL8040 measures 8" × 40" and has an average permeate flow rating of 10,500 GPD ±15% at 150 PSI under manufacturer test conditions using 1,500 ppm NaCl feedwater at 15% recovery.
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?
The SP-UL8040 has a published maximum recommended feedwater NaCl concentration below 5,000 ppm. Suitability for a particular application depends on feedwater composition, pretreatment and system operating requirements.
Which membranes can the SP-UL8040 replace?
The SpiroPure SP-UL8040 is listed as a compatible alternative for select 8" × 40" industrial RO membranes, including DuPont FilmTec ECO PRO-400, Toray TMG20D-400 and Hydranautics ESPA1 / ESPA2. Confirm the exact replacement model, membrane dimensions and system operating requirements before ordering.
