ETD: If the ETD has been improperly changed to a higher size code from “B-22” to “B-25,” product water flow will
increase along with higher-than-normal operating pressure. The High-Pressure Sensor will eventually signal the
system to shut down due to excess pressure at the membrane.
If the ETD has been improperly changed to a lower size code from “B-25” to “B-22,” product water flow will decrease
along with lower-than-normal operating pressure and poor product water quality.
Feed PUMP: If the Feed Pump has been improperly changed to a higher size code (i.e., from 100 GPH to 140
GPH) product water flow will increase along with higher-than-normal operating pressure. The High-Pressure Sensor
will eventually signal the system to shut down due to excess pressure at the membrane.
If the Feed Pump has been improperly changed to a lower size code (i.e., from 190 GPH to 125 GPH) product
water flow will decrease along with lower-than-normal operating pressure and poor product water quality.
RO MEMBRANE ELEMENT: If the RO Membrane Element has been improperly changed to a HIGHER size code
from “A” to “B” or “C” or from “B” to “C,” then product water flow will not change and the operating pressure will
decrease resulting in poor product water quality.
If the RO Membrane Element has been improperly changed to a lower size code from “B” to “A” or from “C” to “B”
or “A,” then product water flow will not change but the operating pressure will increase. The High-Pressure Sensor
will eventually signal the system to shut down due to excess pressure at the membrane.
Product Water Abnormalities
• Insufficient Product Water Flow
• Excessive Product Water Flow
• Poor Quality Product Water
The production of the system (product water flow) and the quality of the product water (high quality indicates low
salinity; low quality indicates high salinity) are dependent upon the proper amount of feed water flow and operating
pressure at the RO Membrane Element. Product water flow or quality abnormalities can be the result of pressure
abnormalities described on the previous pages, which are repeated below.
Production abnormalities can also be the result of worn seals, worn O-rings, cracks or damage at sealing surfaces,
or a fouled RO Membrane Element.
Quality abnormalities can also be the result of worn seals, worn O-rings, cracks or damage at sealing surfaces,
or a fouled RO Membrane Element, Feed Water Temperature, and/or feed water salinity.
Lower-Than-Normal Product Water Flow
A blockage in the suction line, resulting in a heavy vacuum reading at the Feed HP Inlet Pressure, will cause the
Feed Pump to cavitate and lead to a reduction of feed water flow and Feed Pump outlet pressure. The Seafari
Quest System is designed to recover a set percentage of the feed water as product water. Therefore, if the Feed
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 HP Inlet Pressure, will
restrict the Feed Pump water flow and feed water pressure at the outlet of the prefilters. Again, the Seafari Quest
System is designed to recover a set percentage of the feed water as product water. Therefore, if the Feed 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 HP Inlet Pressure and Membrane Pressure will all register
higher-than-normal pressure as the system self-adjusts to overcome the fouling. The High-Pressure Sensor will
eventually signal the system to shut down due to excess pressure at the Membrane when pressure increases to
925 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 Quest 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 Quest 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 Sensor will eventually signal the system to shut down due to excess
pressure at the Membrane when this pressure increases to 925 PSI.
