MEMBRANES ARE SHIPPED WITH AN ANTI-BACTERIAL PRESERVATIVE. OPERATE THE SYSTEM FOR 1 HOUR THE
TO ASSURE MEMBRANE HAS BEEN COMPLETELY FLUSHED. DO NOT USE WATER PRODUCED DURING THIS RUN-IN
PERIOD.
2.6. Recovery Rates
Your VectaMaxx™ RSL 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 40% for feed water with TDS ranging from 1000 to 2000.
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 recycle valve flow. This, done in balance, will maintain
the overall system pressure at previously stated normal operating pressures. Adjust the reject valve to set the flow rate using the flow
meters and close the recycle valve until the pressure registers normal operating pressure. Compare flow rates using the formula:
% Recovery Rate = Flow rate of Permeate (Product Flow)
Permeate Flow rate + Waste Flow rate
Once the new balance has been established at normal operating pressure, you may wish to lock the valve in position by removing the
handles. This can be done by loosening the setscrews located in the valve handle.
!
DO NOT ATTEMPT TO OPERATE THE SYSTEM AT HIGHER RECOVERY RATES, AS THIS WILL CAUSE PREMATURE
MEMBRANE FAILURE OR INTERNAL SCALING AND EQUIPMENT FAILURE.
