Lower-Than-Normal Product Water Flow
A blockage in the suction line, resulting in a heavy vacuum reading at the Booster Pump Inlet Compound
Vacuum/Pressure Gauge, will cause the Booster Pump to cavitate and lead to a reduction of feed
water flow and Booster Pump outlet pressure. The Seafari Escape System is designed to recover as
product water a set percentage of the fed water. Therefore, if the Booster Pump flow decreases due
to cavitation, then the product water flow will decrease accordingly.
Likewise, a blockage in the prefiltration, resulting in an excessive pressure reading at the Prefilter Inlet
Pressure Gauge, will restrict the Booster Pump water flow and feed water pressure at the outlet of the
prefilters. Again, the Seafari Escape System is designed to recover as product water a set percentage
of the feed water. Therefore, if the Booster Pump flow decreases due to a blockage at the prefiltration,
then the product water flow will decrease accordingly.
A decrease in product water flow can also be caused by a fouled RO Membrane Element. However,
as the RO Membrane Element becomes fouled, the Prefilter Inlet Pressure Gauge, the Prefilter Outlet
Pressure Gauge, and the High-Pressure Gauge will all register higher-than-normal pressure as the
system self-adjusts to overcome the fouling. The High-Pressure Switch will eventually signal the system
to shut down due to excess pressure at the Prefilter Inlet Pressure Gauge when pressure increases
to 190 PSI.
Lower-than-normal feed water temperature causes the RO Membrane to require greater operating
pressure in order to maintain the normal product water production. The Seafari Escape System
self-adjusts by increasing the operating pressure to compensate for lower-than-normal feed water
temperature.
A blockage in the product water line will cause lower-than-normal product water flow. The Seafari
Escape System will attempt to self-adjust the operating pressure to overcome the drop in product
water flow caused by a blockage in the product water line. The High-Pressure Switch will eventually
signal the system to shut down due to excess pressure at the Prefilter Inlet Pressure Gauge when this
pressure increases to 190 PSI.
Higher-Than-Normal Product Water Flow
Mismatching of system components can cause higher-than-normal product water flow accompanied
by increased operating pressure. The High-Pressure Switch will eventually signal the system to shut
down due to excess pressure greater than 190 PSI at the Prefilter Inlet Pressure Gauge.
A worn or broken product water O-ring at the end plug inside the high-pressure vessel will allow feed
water to bypass into the product water to produce a greater-than-normal amount of product water.
The resulting mixture of product water and feed water will be of low quality, or high in salinity. This will
also show up as lower-than-normal operating pressure at the Operating Pressure Gauge.
A crack in the end plug between the feed water port and product water port or a rough surface at the
product water O-ring will also allow feed water to bypass into the product water causing the product
water flow to increase. The resulting mixture of product water and feed water will be of low quality, or
high in salinity. This will also show up as lower-than-normal operating pressure at the Operating
Pressure Gauge.
Higher-than-normal feed water temperature causes the RO membrane to require less operating
pressure in order to maintain the normal product water production. The Seafari Escape System
self-adjusts by decreasing the operating pressure to compensate for higher-than-normal feed water
temperature. Product water quality will decrease, or increase in salinity, as the operating pressure is
decreased to compensate for the higher-than-normal feed water temperature.
