The above values will vary with the actual cycles (Hz) that is supplied to the System or in the case of Direct
Current (12 VDC or 24 VDC) powered Systems the values will vary with the actual voltage that is supplied to
the System. This is to say, the lower the Hz from the 50 or 60 Hz norm the less the amount of Feed Water and
resulting decrease in Product Water. Inversely, the higher the Hz from the 50 or 60 Hz norm the greater the
amount of Feed Water and resulting increase in Product Water. As for Direct Current powered Systems, the
lower the voltage from the 12 or 24 VDC norm the less the amount of Feed Water and resulting decrease in
Product Water. Inversely, the higher the voltage from the 12 or 24 VDC norm the greater the amount of Feed
Water and resulting increase in Product Water.
PRESSURE CHANGES:
The System Operating Pressure (the pressure applied to the R.O. Membrane Element) varies with the Feed
Water Temperature, the Feed Water Salinity, and the condition of the R.O. Membrane Element. The System
Design Specifications are based on Feed Water Temperature of 77° F / 25° C, and a Feed Water Salinity of
35,000 PPM-TDS (parts per million-total dissolved solids). Each R.O. Membrane Element can vary +/- 15%
which will cause the final Operating Pressure to decrease or increase accordingly. However, assuming the
“perfect R.O. Membrane”, at this temperature and salinity the system will operate at the standard system
pressure listed within the Specifications at the beginning of this Owner’s Manual.
If the Feed Water Salinity increases or if the Feed Water Temperature decreases the System Operating
Pressure will increase. Inversely, if the Feed Water Salinity decreases or if the Feed Water Temperature
increases the System Operating Pressure will decrease. Further more, if the R.O. Membrane Element is new or
old and fouled the System Operating Pressure Automatically decreases or increases accordingly to over come
the R.O. Membrane Element condition.
Operating Amperage and Operating Pressure Will Increase if:
the Feed Water Temperature is Lower than 77º Fahrenheit / 25º Celsius.
the Feed Water Salinity is Greater than 35,000 PPM TDS (3.5% Total Dissolved Solids)
the R.O. Membrane Element becomes fouled
the R.O. Membrane Element is new and on the minus 15% side of the specifications
Operating Amperage and Operating Pressure Will Decrease if:
the Feed Water Temperature is Higher than 77º Fahrenheit / 25º Celsius.
the Feed Water Salinity is Less than 35,000 PPM TDS (3.5% Total Dissolved Solids)
the R.O. Membrane Element is new and on the plus 15% side of the specifications
By monitoring Feed Water Salinity, Temperature, and resulting System Operating Pressure it is possible to
measure and monitor the fouling of the R.O. Membrane Element over time and use.
As the feed water vane pump becomes worn from normal use it will loose flow and ability to build up pressure.
A reduction in product water production could be caused by insufficient pressure and or flow from the feed
water pump. Should the feed water pump become worn resulting in reduced pressure and or flow it may be
returned to Sea Recovery for re-build or replacement. Because of the specific matching requirements of the
wear parts and tight tolerance it is not practical to repair in the field.
