Product Water Subsystem; Fresh Water Flush Subsystem; Electronic Subsystem - Sea Recovery Aqua Mini 170 Owner's Manual

4. Back Pressure Regulator By turning the valve adjustment handle clockwise and counterclockwise, pressure is
increased and decreased accordingly. This increases and decreases the production of the RO Membrane
Element.
5. Thru Hull Discharge Fitting ** should be installed above water level for discharge of the Brine Discharge Water
from the system.

Product Water Subsystem

This section of the system gives a visual indication of the clarity, quantity, and quality of the product water. Post
Filtration is the final step in Product Water quality control. The Post Filtration Subsystem is designed to limit
unpleasant odor and taste, as well as sterilize biological matter, which may have passed through the RO Membrane
Element.
1. Temperature Compensated Salinity Probe electronically determines whether the salinity content of the Product
Water is acceptable. This Salinity Probe is temperature compensated and provides an accurate measurement
of Product Water quality.
2. Flow Meter, Product Water measures the rate of Product Water flow, in gallons and liters per hour. It measures
from the RO Membrane Element toward the Product Water Post Filtration Components.
3. 3-Way Product Water Diversion Valve, Electric Solenoid Actuated, the 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", high in salinity, then no signal is sent to the valve, and it thus remains
in the normal open position. The "fail safe" normal open position diverts the un-potable Product Water to
discharge.
4. Charcoal Filter *** is designed to remove foul odors from the Product Water. Sulfurous odor (rotten eggs) is
caused when decaying biological matter in the feed water section. Fresh water flushing of the system helps to
minimize this.
5. Ultra Violet Sterilizer*** destroys at least 99.9% of any virus, bacteria, and other micro-organisms which may
pass through the RO Membrane Element. The UV sterilizer is recommended if the Product Water Storage Tank
is not otherwise treated by means such as chlorination.
6. pH Neutralizer Filter*** The product water from the system will be slightly acidic. The pH Neutralizer Filter
neutralizes the pH of the product water.
7. Potable Water Storage Tank** may be any container suitable for storing Potable Water, i.e. existing water
storage tank.

Fresh Water Flush Subsystem

Consists of supplied valves and required tank or container for the cleaning, rinsing, or storage of the RO System.
1. Fresh Water Flush System*** (including charcoal filter and solenoid valve) automatically flushes the system
with fresh water. This process is automatic at each shut down of the system and repeats automatically every
7 days. Fresh Water Flushing replaces the seawater in the system with less corrosive fresh water, and this also
reduces the biological decay as well as biological growth that naturally occur if the feed water (sea water) is
not flushed from the system with fresh water.
2. Fresh Water Flush Check Valve Assembly *** included with the Fresh Water Flush Optional Assembly, isolates
the Fresh Water Flush system which prevents seawater from flowing in the reverse direction through the Charcoal
Filter.
3. Future Reference
4. Inlet Rinse Clean Valve *** (optional) used in conjunction with the Discharge Rinse Clean Valve [31] simplifies
the storage and cleaning procedures by allowing the operator to turn a valve rather than disconnect a hose.
Also used for a manual fresh water flush if the Automatic Fresh Water Flush System [25] is not installed.
5. Discharge Rinse Clean Valve *** (optional) used in conjunction with the Inlet Rinse Clean Valve [30] simplifies
the storage and cleaning procedures by allowing the operator to turn a valve rather than disconnect a hose.

Electronic Subsystem

This subsystem measures water quality, controls the direction of Product Water flow, Starts and Stops the pumps,
and contains the central electrical connection point of the system. It also ensures only potable Product Water
passes into the Product Water Storage Tank.
