The recommended flux rate for maximum membrane life
should not exceed 16.5 GFD
NOTE:
VALUES LISTED ABOVE ARE NOMINAL FLOW RATES BASED ON AVERAGE FEED WATER CONDITIONS. A
CHANGE IN WATER TEMPERATURE AND OR WATER QUALITY CAN SIGNIFICANTLY ALTER THE
ACHIEVABLE FLOW RATES OF THE RO SYSTEM.
TO OBTAIN OPTIMAL OPERATING PARAMETERS FOR
YOUR
SYSTEM, BASED ON
YOUR
FEED WATER
CONDITIONS, PLEASE SUBMIT A WATER ANALYSIS OF
YOUR
FEED WATER TO THE U.S. FILTER
ENGINEERING DEPARTMENT, AND WE WILL RUN A COMPUTERIZED RO PROJECTION FOR YOUR SYSTEM.
OPERATING THE RO UNIT OUTSIDE OF THESE PARAMETERS COULD CAUSE PREMATURE MEMBRANE
FAILURE OR RESULT IN ECSESSIVE CLEANING REQUIREMENTS.
