1 THEORY OF OPERATION
A reverse osmosis unit makes a limited amount of water at a time. It is therefore necessary to store it in
a storage tank. The laboratory storage tank is equipped with float switches, which will turn a reverse
osmosis unit off and on when the water reaches a predetermined point in the storage tank. The
distribution pump will operate on a constant curve based on the run percentage "SETPOINT", any unused
water will recirculate back to the storage tank.
The pump sends the water to the deionizer or customer provided DI tanks. The water from the DI will
pass across a resistivity cell, through the UV disinfection through a filter, and then will be sent to the
point of use.
This tank is also equipped with a spray nozzle on the return loop side of the tank. This will continuously
spray down the top of the tank with purified water to minimize bacteria growth. During disinfection, the
spray nozzle allows disinfectant to reach all parts of the tank for faster disinfections.
The vent filter on the tank is designed to filter the air when water moves in and out of the storage tank.
The filter must be immediately replaced if it gets wet.
