5. Next, begin to close the recirculation valve slowly until the operating pressure gauge registers 150
psi (10.3 bar). The system is designed to normally operate at 130 psi. At this pressure, the proper
waste/production ratio is established.
DO NOT ALLOW THE SYSTEM TO OPERATE IN EXCESS
OF 150 PSI AS MEMBRANE AND SYSTEM DAMAGE MAY RESULT.
You may wish to lock the
valve in the proper position by removing the handle to discourage tampering. Your system is now
set up to operate at its design settings.
!
YOUR MEMBRANES MAY HAVE BEEN SHIPPED WITH AN ANTI-BACTERIAL PRESERVATIVE.
OPERATE THE SYSTEM FOR 1 HOUR AT DESIGN SETTINGS BEFORE BRINGING THE SYSTEM
ONLINE TO ASSURE MEMBRANE HAS BEEN COMPLETELY FLUSHED. DO NOT USE WATER
PRODUCED DURING THIS RUN-IN PERIOD.
A Note on Recovery Rates
Your Vectapure ™ RSX II is designed to operate at a recovery rate (percentage of product water to
total water used) at maximum of 60% for feed water of <1000 TDS and 35-40% for feed water with
TDS ranging from 1000 to 2000.
DO NOT ATTEMPT TO OPERATE THE SYSTEM AT HIGHER
RECOVERY RATES, AS THIS WILL CAUSE PREMATURE MEMBRANE FAILURE OR INTERNAL
SCALING AND EQUIPMENT FAILURE.
You may wish to operate your system at lower recovery rates where your dealer has identified water
conditions that may stress your membrane or where recommended pre-treatment feed water conditions
are not met. You may do so, though this must be accomplished by a combination of increasing the flow
of concentrate to waste and reducing the recirculation valve flow. This, done in balance, will maintain
the overall system pressure at previously stated normal operating pressures.
