DRISTEEM RO 200 SYSTEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
MEMBRANE CLEANING IN THE RO SYSTEM
Membrane cleaning cartridges:
• Clean membranes without having to remove them from the RO system
• Reduce downtime
• Maintain the system performance at a higher level
• Prolong membrane life by regular use of cleaning cartridges
HOW DOES IT WORK?
NOTE: Clean monthly to obtain optimum results.
1. Exchange the system's sediment filter with a cleaning cartridge.
2. Follow
the
instructions.
3. Restart the system.
4. Repeat the process if required.
SCALE CLEANING CARTRIDGE
The scale cleaning cartridge is for removal of mineral scale and build-up.
CLEANING PROCEDURE
1. Put the system into 'Standby' mode and shutdown the RO system.
2. Disconnect permeate line and divert to drain before any cleaning
cartridge is installed.
3. Remove the sediment filter from the pre-filter housing.
4. Replace the sediment filter with the cleaning cartridge and assemble into
the filter housing.
5. Turn the system ON and put into 'Auto' mode. After 30-40 seconds, shut
down the system.
OPTIONAL: Instead of time, use one of the following criteria:
a. Run the system until the pH of the concentrate is almost the same as the
cleaning solution (pH=3)
b. Permeate rate for the system drops to a very low value.
6. Let the membrane(s) soak in the cleaning solution overnight.
7. Remove the empty cleaning cartridge and replace it with the original filter.
8. Restart the system. Direct the permeate to drain for five minutes.
9. Go back to normal operations.
