A. PRODUCT WATER FLOW OR QUALITY ABNORMALITIES:
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 R.O. 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 R.O. Membrane Element.
Quality abnormalities can also be the result of worn seals, worn o-rings, cracks or damage at sealing surfaces, or a
fouled R.O. 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 Pump Inlet Compound
Vacuum/Pressure Gauge [5] will cause the Feed Pump [6] to cavitate resulting in a reduction of Feed Water Flow
and Feed Pump Outlet Pressure. The Ultra Whisper System is designed to recover as Product Water a set
percentage of the Feed 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 Prefilter Inlet Pressure
Gauge [12] will restrict the Feed Pump Water Flow and Feed Water Pressure at the Outlet of the Prefilters.
Again, the Ultra Whisper System is designed to recover as Product Water a set percentage of the Feed 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 R.O. Membrane Element. However, as the R.O.
Membrane Element becomes fouled the Prefilter Inlet Pressure Gauge [12], the Prefilter Outlet Pressure Gauge
[16], and the High Pressure Gauge [18] will all register higher than normal pressure as the System self adjusts to
overcome the fouling. The High Pressure Switch [11] will eventually signal the System to shut down due to
excess pressure at the Prefilter Inlet Pressure Gauge [12] when pressure increases to 190 PSI.
Miss-matching of System Components as explained on pages 16 - 18 of this section can cause lower or higher than
normal product water flow.
Lower than normal Feed Water Temperature causes the R.O. Membrane to require greater operating pressure in
order to maintain the normal Product Water production. The Ultra Whisper 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 Ultra Whisper
System will attempt to self adjust the operating pressure to over come the drop in Product Water Flow caused by
a blockage in the Product Water Line. The High Pressure Switch [11] will eventually signal the System to shut
down due to excess pressure at the Prefilter Inlet Pressure Gauge [12] when this pressure increases to 190 PSI.
Higher Than Normal Product Water Flow:
Miss-matching of System Components as explained on pages 16 - 18 of this section can cause higher than normal
product water flow accompanied by increased operating pressure. The High Pressure Switch [11] will eventually
signal the System to shut down due to excess pressure greater than 190 PSI at the Prefilter Inlet Pressure Gauge
[12].
A worn or broken Product Water O-ring at the End Plug, inside the High Pressure Vessel [20], will allow Feed
Water to by-pass into the Product Water to produce a greater than normal amount of Product Water. The
