b. POSSIBLE CAUSE: HIGH SALINITY FEED WATER.
1) The System may be operating and reacting normal in relationship to the Feed Water Salinity and
Temperature. Refer to the Salinity, Temperature and Operating Pressure Charts in Section 10 of this
manual to ensure that the System is being operated within the Feed Water Salinity limits stated, and
or that the resulting operating pressure is at the expected pressure according to the charts.
c. POSSIBLE CAUSE: FOULED R.O. MEMBRANE ELEMENT
1) Refer to the Charts in Section 10 of this manual. Project the expected operating pressure with the given
Feed Water Temperature and Salinity to determine if the System is operating within expected limits.
If the operating pressure is greater than the expected limits this could indicate that the R.O.
Membrane Element may have a moderate degree of fouling and may require cleaning.
This would be applicable only to a used system, used R.O. Membrane Element. If the system is new
and just being operated for the first time the R.O. Membrane Element may have dried out if the
system has been sitting unused for an extended period of time from the date of shipment. Contact Sea
Recovery to determine shipment date and delay in installation if applicable.
2) Refer to System Storage & R.O. Membrane Element Cleaning Section 5 of this manual.
d. POSSIBLE CAUSE: BLOCKAGE IN THE BRINE DISCHARGE LINE
Any restriction or blockage in the Brine Discharge Line will cause excessive operating pressure.
1) Ensure that the Discharge Rinse Clean Valve [37], if installed, is positioned towards the Brine Discharge
fitting [22].normal operating position.
2) Ensure that any valve in the Brine Discharge Line or at the Thru Hull Discharge Fitting [22] is full
OPEN.
3) Ensure that there are no kinks or other blockages in the Brine Discharge Line.
e. POSSIBLE CAUSE: BLOCKAGE IN THE PRODUCT WATER LINE
Any restriction or blockage in the Product Water Line will cause excessive operating pressure.
1) Ensure that any valve in the Product Water Line is full OPEN.
2) Ensure that there are no kinks or other blockages in the Product Water Line.
