General Cleaning Instructions
The following general cleaning procedure can be
followed. For the optimum cleaning procedure for
your system, contact your GE representative.
1. Inspect cleaning tank, hoses, and cartridge
filters. Clean tank and flush hoses if necessary.
Install new cartridge filters.
2. Fill cleaning tank with RO permeate or DI
water. Turn on agitator or tank recirculation
pump.
3. Slowly add Kleen MCT524 to cleaning tank
in order to prepare a solution of 1- 2,5 % con-
centration, based on the CIP total volume and
the product strength needed and allow to mix
thoroughly.
4. Check solution temperature. If solution tem-
perature is lower than recommended level,
adjust heating control to provide optimum
temperature. If manufacturer’s recommenda-
tion is not available, contact your GE repre-
sentative.
5. Check solution pH. The solution pH should be
<12 or as recommended by the membrane
manufacturer. If pH is too low, adjust pH
upward with NaOH, or other chemical as rec-
ommended by the membrane manufacturer.
If pH is too high, adjust with hydrochloric acid.
6. Circulate solution through one stage at a time
in the direction of feed flow for 30 minutes.
Circulate at the flow rate recommended by
the membrane or system manufacturer. If
manufacturer’s recommendation is not avail-
able, contact your GE representative. Pressure
should be low enough so that minimal perme-
ate is produced during cleaning, but always
less than 60 psig (4.2 kg/cm
2 ).
7. In cases of heavy fouling, the first return flow
(up to 15% of the cleaning tank volume)
should be diverted to drain to prevent
redeposition of removed solids. For optimum
results, each stage must be cleaned separate-
ly in a multistage system.
8. If the first stage cleaning solution becomes
turbid or discolored, dump the tank and pre-
pare a fresh cleaning solution before proceed-
ing. If solution pH or temperature moves out of
the recommended range, a new solution
should be prepared. In any event, a new
cleaning solution should be prepared for each
stage.
9. Rinse with RO permeate before returning
system to service.
10. When returning unit to service, divert product
water to drain until any residual cleaning solu-
tion has been rinsed from system.
Depending on the nature of the fouling, a soak
period may be necessary for optimum results.
Consult your GE representative for details.
