GE E4LE - Manual (Page 23)

When set properly, the RO machine, the CIP pump, and the CIP con-
tainer should be assembled in a loop configuration to recirculate the
water through the machine and back to the container during clean-
ing. The size of the CIP container should be a minimum of three times
the permeate rate.
CAUTION GE recommends the use of a CIP or booster pump to
provide the proper feed water pressure and quantity
to the RO machine during cleaning.
Figure 2.5
Clean-In-Place Pump
and Tank Hook-Up
With the machine set-up in the CIP configuration and the cleaning solution
mixed in the container, you are now ready to start the CIP process. Follow the
Steps below.
STEPS
1. Check to ensure that the feed, permeate, and concentrate valves and
line are open and unrestricted in the tank loop.
2. Start the CIP and RO machine pumps together. As they start up,
observe all RO machine pressures and flows.
3. Recycle the cleaning solution for about 15 minutes. Damage may
result to membrane elements if the temperature of the CIP solution
exceeds 105°F (40°C). If the water temperature exceeds 100°F (38°C),
place bags of ice into the CIP container to absorb the extra heat.
4. After recirculating the cleaner for 15 minutes, shut down the RO and
the CIP pump.
