months, increases, quality decreases:
As the Reverse Osmosis Membrane Element is
exposed, operated or not, to Sea Water eventually
biological matter will coat the membrane surface
causing a drop in production, loss of product water
flow accompanied by an increase in salt passage
in the product water. Fresh Water Rinsing will
minimize and slow down the biological fouling that
naturally occurs. Chemical Cleaning at appropriate
intervals will remove the biological fouling and
extend the life of the R.O. membrane element.
Solution: Refer to Section 7 R.O. membrane
element Cleaning procedures or replace the R.O.
membrane element(s).
As the RO membrane element is operated
eventually dissolved solids, salts or minerals,
will build up on the membrane surface causing
a drop in production, loss of product water
flow accompanied by an increased percentage
of dissolved solids, salt, in the product water.
Chemical Cleaning at appropriate intervals will
dissolve the salt and mineral fouling and extend
the life of the R.O. membrane element.
Solution: Refer to Section 7 for R.O. membrane
element cleaning procedures or replace the R.O.
membrane element(s).
d) Product Water Flow suddenly decreases and
Product Water Salinity, suddenly increases,
quality decreases:
Chemical, one that will foul or plug up the
membrane surface, or Oil attack to the R.O.
membrane element will cause the production to
suddenly decrease and the product water quality
will suddenly worsen.
Solution: Replace the R.O. membrane element(s)
if they have been attacked by Chemicals or Oil.
e) Feed Water leaks from the Pressure Vessel:
The High Pressure fittings entering the Pressure
Vessel are O-Ring sealed at the End Plug that they
attach to. Should a leak develop at a High Pressure
Fitting inspect the respective O-Ring for signs of
wear or damage.
Solution: Replace the O-Ring if wear or damage
is present.
The End Plugs seal against the inner surface of the
High Pressure Vessel. The O-Ring that creates this
Page 9-12
seal is the "Brine O-Ring". Should a leak develop
between the End Plug and the inside wall of the
Pressure Vessel remove the end plug and inspect
the Brine O-Rings for wear or damage. Replace
them if wear or damage is present.
Solution: Replace the O-Ring if wear or damage
is present.
23) HIGH PRESSURE MANIFOLD
There are no parts within the High Pressure Manifold
that would require troubleshooting. If it is broken or leaks
then replace it.
24) HIGH PRESSURE TRANSDUCER
The High Pressure Transducer attaches to the High
Pressure Manifold measures the System Operating
Pressure from the Outlet of the High Pressure Pump
through the R.O. membrane and vessel and into the
Automatic Back Pressure Regulator.
The High Pressure Transducer sends a DC voltage
signal to the System Control Logic. The minimum value
is 0.5 VDC when no pressure is applied to it, and the
maximum value that the System will accept is 4.5 VDC.
The variation of voltage output from the Transducer is
converted to pressure value by the System Control Logic.
Problems and Symptoms appearing and caused by the
High Pressure Transducer:
a) The High Pressure Transducer does not register
pressure or the pressure displayed is inaccurate.
The pressure readings at the Touch Pad are
inaccurate. The minimum voltage output is below
0.5 VDC and or the maximum voltage output is
above 5 VDC.
Solution: Check wiring and connections to and
from the Transducer. Replace the Transducer.
25) AUTOMATIC MOTOR ACTUATED BACK
PRESSURE REGULATOR
Automatic Motor Actuated Back Pressure Regulator is a
U.S. Patent Pending device that automatically
adjusts the system operating pressure to varying feed
water temperatures and salinities making the Sea
Recovery System a truly self functioning and fully
automatic watermaker.
The Motor Control is sealed against moisture and
encased within an anodized aluminum housing. The
Motor Control is not serviceable. Do not attempt to
remove the anodized aluminum housing from the bracket
