The PRF-750-RO membrane is an upgrade alternative to the PENTAIR TLC-350 membrane which is supplied with our standard PRF-RO System. With two PRF-750-RO membranes incorporated into a PRF-750 System, the high flow membranes work in series to produce on average 70% more water than the TLC-350 membrane. The design of this system also enables the concentrate from one membrane to be channelled through the second on the system, allowing waste water to be reduced by approximately 75% compared to conventional systems.
