a. Depending on the nature of the fouling, a soak period may be necessary.
If the membranes are not heavily fouled, proceed to step 11.
b. In cases of heavy fouling, turn off the RO and CIP pump and allow the
system to soak for a minimum of 30 minutes.*
* Contact AmeriWater Technical Support or your local AmeriWater dealer for custom cleaning procedures if
necessary.
c. After the soak time, turn on the CIP pump and RO, and allow the cleaning
solution to recirculate again for 30 minutes.
12. Disconnect the pump outlet hose from the CIP tank and direct the hose to a
drain. Continue running to drain until the CIP tank is empty (some solution
may need to be manually dumped out of the CIP tank).
CAUTION:
Neutralization of the spent cleaning solution may be required
by local regulations. Verify the requirements of local
regulations prior to emptying the cleaning solution into the
drain. Use an approved waste container for chemical waste
disposal if required.
13. After removing the spent chemical from the CIP2 tank, and with the CIP2
pump discharge directed to drain, turn on the MRO and allow fresh water to
flow into and through the RO and CIP2 for 10 minutes or until the pH of the
water at the pump discharge is neutral (between 6 and 8).
14. Proceed to the low pH cleaning.
WARNING: Never allow AmeriClean A and AmeriClean B to mix! Mixing the
chemicals will cause an exothermic reaction which may result in
serious injury and damage to the equipment! Flush the system
thoroughly and verify the pH of the reject water is neutral prior to
switching chemicals!
NOTE:
The 20” filter housings may trap some left over chemical solution causing
rinse out times to be high. To shorten the rinse time, remove and dump the filter
housing, then reinstall in the system. This allows the housing to fill with fresh
water and reduces time required for rinsing.
