An Auto-Flush Flow Restrictor will assist the RO membrane to perform with maximum efficiency for longer time periods. At BRS, we recommend that an RO system be flushed on a regular basis. The use of this auto-flush flow restrictor can reduce the “brine to product” ratio, especially in low “TDS” applications, while maintaining or improving system “TDS” rejection rate and extending membrane sediment and carbon filter life.
Upon system start-up and every hour thereafter, the 24VAC normally closed solenoid valve automatically “power flushes” the membrane at full pump flow, or full line pressure in unboosted systems, for 18 seconds every hour. Turbulent water action scrubs organic and inorganic contaminant’s from the membrane surface, extending membrane life and efficiency.
The “power flush” system only occurs only while the system is in the water-making mode. The flush cycle is reset automatically when the RO system repeats the “water making” mode after the “full tank shut-down” mode. Water that has been standing idle in the membrane module for an extended period is purged to the drain.
The PFR requires its own transformer or can be powered by the pump transformer. The valve has a built-in, self-cleaning, flow restrictor which allows the controlled flow to drain when the valve is in the de-activated (closed) state.
