OPERATOR INSTRUCTIONS
REVERSE OSMOSIS SYSTEM DETERGENT CLEANING OPERATION
UNDER USUAL CONDITIONS
CAUTION
Failure to add sodium bisulfite to the chlorinated product water that is used for
cleaning will result in RO membrane failure.
NOTE
Open one of the 12oz sodium bisulfite packets and pour it into the bottle provided
in the BII. The bisulfite powder will be used to neutralize the chlorine in the
product water when product water is required for cleaning.
f.
Add one cap of sodium bisulfite from the sodium bisulfite bottle to the RO feed tank while
filling the tank to neutralize the chlorine in the product water.
g. Reset the RO Feed Tank Low Alarm.
h. Start the RO feed pump. This circulates the solution from the RO feed tank, through the
RO feed pump, through Clean Mixing Valve V-703, and back into the tank to provide
mixing when the membrane detergent cleaner is added to the water. Silence any alarms.
i. Set the Tank Heater Switch to AUTO 2.
6. Prepare the RO detergent cleaning solution as follows:
WARNING
Chemical hazard. Wear a dust mask, a protective face shield, chemical gloves, and
a chemical apron when handling detergent cleaner. Avoid eye and skin contact.
Keep water ready when handling. Avoid inhaling or ingesting dust. Wash
thoroughly after handling. Failure to observe this warning may result in mild
irritation of the nose, throat, eyes, and skin.
CAUTION
Do not add caustic when detergent cleaning the RO.
NOTE
Rapid pouring of membrane detergent cleaner into the tank will cause the cleaner
to stick to the tank bottom and not mix. Unmixed cleaner may be drawn to the
pump and interrupt pumping.
a. Make sure a bucket of product water is placed in the operator station and also near the
wastewater tanks to rinse any area of skin or clothing that comes in contact with acid
cleaner.
b. Hook the RO feed tank cover open.
c. VERY SLOWLY add AC-310 Membrane Detergent Cleaner into the RO tank to ensure
that it is mixed thoroughly with the water and to avoid splashing chemicals. Repeat until
four (4) containers of detergent have been added. Maintain recirculation.
d. Close the RO feed tank cover.
e. Rinse the chemical gloves with product water in the bucket before removing.
