6. LOW pH CLEANING
AmeriClean A
is used second for the removal of inorganic scale and metals.
1.
Fill the CIP tank with RO product water (or softened water) to about 25”
deep in the tank. Water at 25” deep in the tank is approximately 27 gallons.
Water should be at or near 86
°
F for the maximum cleaning effect.
2.
Slowly add 3 lb (800 ml) [3 full bags] of
AmeriClean A
powder to the water
in the cleaning tank.
3.
Agitate the solution until the powder completely dissolves.
It is important to
make sure all of the powder is dissolved before continuing.
WARNING: Wear appropriate eye and skin protection when handling the
membrane cleaning chemicals. The cleaners are high and low pH
chemicals and may cause severe chemical burns. Read the MSDS
for further information.
4.
Connect the power cord of the CIP2 pump to a 120 VAC receptacle and
allow the solution to begin circulating.
5.
Turn the MRO on and verify that the cleaning solution is recirculating and
flowing from the drain hose inside the CIP tank.
6.
Allow the cleaning solution to recirculate for a minimum of 50 minutes.
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.
7.
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.
