THEORY OF OPERATION LAB STORAGE TANKS
3 98-0123 Rev E
1THEORY 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.
NOTE: Please read the Operation Manual before operating or servicing the system. Contact
AmeriWater Customer Service with any questions at 1-800-535-5585 Monday through Friday 8:00 a.m. to
5:00 p.m. eastern standard time. For after-hours emergencies follow the instructions on the recorded
message. Our on-call technician will return your call as soon as possible. This Operation Manual should
be kept near the system and used as a reference and troubleshooting guide.

OPERATION LAB STORAGE TANKS
11 98-0123 Rev E
5OPERATION
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 (see Section 4.1.1 to adjust the "SETPOINT"). The
tanks are equipped with a recirculation header that contains a pressure relief valve, spray bar, dump
valve, pressure gauge, temperature gauge, and sample port. The pressure relief valve works to maintain
water pressure under its set-point. The spray bar returns water from the distribution loop back to the
storage tank using spray nozzles to prevent stagnant water.
The laboratory storage tanks are equipped with three float switches: high-level, mid-level, and base-level.
All three float switches are close on rise and the high and mid-level floats tie into the RO. The high-level
float closing turns off the RO, while the mid-level float opening turns the RO on to request more water.
The base-level float connects to the CME distribution pump to act as a kill switch to prevent the pump
from operating when there is no water (running dry).
All CME pumps provided from AmeriWater have been factory set to control mode “Controlled” (see
paragraph below) and have been programmed to operate on a constant curve at the rated flow
mentioned previously. These models also use a pressure transducer to monitor the discharge pressure
during operation. The transducer allows the pump to recognize when the pump is operating under a dead
head condition (no water usage). Under this condition, the pump will shut off based on a maximum
pressure limit allowed at the pump discharge. To increase or decrease the speed at which the pump
operates, follow steps outlined in Section 4.1.1. The number of starts and stops via the power supply
must not exceed four times per hour. When switched on via the power supply, the pump starts after
approximately five seconds.
NOTE: All changes to set-points are possible with the pump operating.
In control mode “Controlled,”the pump will adjust its performance, i.e., pump discharge pressure, to the
desired set-point for the control parameter. In control mode “Uncontrolled,”the pump will operate
according to the constant curve set.

6DISINFECTION
1. Disconnect the storage tank from the DI process.
2. Remove the 0.2-micron filter (if installed).
3. Prepare DI process for disinfection:
a. If using the Silex deionizer, simply remove the packs from the system and set aside.
b. If using DI tanks, remove the inlet and outlet connections from the DI tanks and jumper
these together.
4. After preparing the DI process:
a. If disinfecting the loop, ensure that all devices downstream are off line and removed
during the disinfection process. If disinfecting the loop with ozone, reference the Ozone
Disinfection System manual, 98-0121.
b. If only disinfecting the tank, remove from the loop and install the short disinfection
jumper hose between the filter outlet and return from the loop. It will be necessary to
loosen the worm gear clamps during installation and removal to these connections.
Ensure clamps are tightened prior to applying pressure to the system.
5. Fill tank with 50 gallons of water from the disinfected RO.
6. Add ½ gallon of bleach.
7. Turn on the pump and allow this to recirculate for 30-60 minutes.
NOTE: The introduction of the bleach solution in to the UV light will trigger a temporary low UV
condition. This is due to the bleach “clouding” the water in the chamber.
8. Drain the water from the system and add 50 gallons of water from the disinfected RO.
9. Allow this to recirculate for a minimum of 30 minutes or until there is no chlorine detected at any
of the points of use.
10. Drain the tank and replace with a new 0.2-micron filter.
11. Reconnect to the DI process and return to service.
