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) BACK PRESSURE REGULATOR
Back Pressure Regulator adjusts the system operating
pressure to varying feed water temperatures and salinities.
The Back Pressure Regulator Valve contains a seal
that is serviceable.
Rotating the Back Pressure Regulator clock wise to
increase operating pressure until the specified flow of
Product water is achieved or until the System Operating
Pressure reaches 950 PSI (66 BAR) which ever comes
first. The System Control Logic will not allow Product
Water production to exceed the specific set flow rate.This
protects the R.O. membrane element(s) from prematurely
fouling. The System Control Logic will also not allow the
System Operating pressure to exceed 950 PSI (66 BAR).
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
seal is the “Brine O-Ring”. Should a leak develop
between the End Plug and the inside wall of the
