15. Pre-Filter Outlet Pressure Gauge 0-300 PSI is mounted on the System Control Panel and monitors
the outlet pressure of the Pre-Filtration section. This Gauge is used along with the Pre-Filter Inlet
Pressure Gauge to determine the condition of the Pre-Filtration Elements.
Pressurization Components
The Pressurization section of your System supplies the proper pressure across the Membrane Element
to produce the required product water within a safe operating condition. Proper pressure and proper
flow across the Membrane Element are two basic requirements of Reverse Osmosis.
1. Energy Transfer Device (ETD) “enhances” (increases) pressure from the Booster Pump by
approximately a 4:1 or 5:1 ratio.
2. Pressurized water from the feed water enters the RO Boost from the ETD port "LP IN". Pressurized
water returns from the RO Membrane Element.
3. The Low Pressure Gauge 0-300 PSI is a stainless steel glycerin filled pressure gauge that is used
to monitor the pressure of the Feed Water entering the ETD.
4. High Pressure Hose, ETD Outlet port "HP OUT"/MVA inlet transfers pressurized Feed Water from
the ETD to the inlet of the RO Membrane Element.
5. RO Membrane Element and Pressure Vessel allows potable water molecules to pass through while
rejecting the salt ions. Only 13% of the Feed Water becomes Product Water. The remainder
(concentrated brine) transfers energy back into the ETD, and then becomes Brine Discharge, which
carries the rejected salt ions out of the Membrane Element.
6. High Pressure Hose, MVA Outlet / ETD Return port “HP IN” transfers pressurized Brine Water from
the Membrane Vessel Assembly back to the ETD. This pressurized water assists the ETD as
recovered energy. This allows the ETD to deliver the required flow and pressure to the RO Membrane
Element with minimal power consumption.
Brine Discharge Components
The Brine Discharge section of your System transfers brine exiting the ETD back to the Feed Water
source.
1. Brine Discharge Tee Connector allows for the Brine Discharge Hose to connect to the Thru Hull
Over Board Discharge Fitting.
2. Thru Hull Discharge Fitting** should be installed above water level for discharge of the Brine
Discharge Water from the System.
Product Water and Post-Filtration Components
This section collects the product water as it exits the RO Membrane Element. The product water is
tested for quality at the salinity probe, enters a 3-Way Product Water Diversion Valve, and then is
measured for flow. When the Product Water Salinity decreases to the “safe” level, it is then diverted
into the Post Filtration components, which are the final steps in Product Water quality control.
1. Product Water Manifold allows transfer of product water flow through the components attached to
it.
2. Temperature Compensated Salinity Probe electronically determines whether the salinity content
of the Product Water has decreased to the “safe” level. This Salinity Probe retains an accurate
reading throughout varying temperature ranges.
3. 3-Way Product Water Diversion Valve, Electric Solenoid Actuated. The Salinity Controller energizes
this valve to the “Potable” position when the System produces water, which meets the low salinity
requirement. If the Product Water being produced is “un-potable” or high in salinity, then no signal
is sent to the valve and it remains in the normally open position. The “fail safe” normally open
