TACTICAL WATER PURIFICATION SYSTEM (TWPS)
OPERATOR INSTRUCTIONS
MICRO-FILTRATION SYSTEM CLEANING OPERATION UNDER
USUAL CONDITIONS
i.
Set the System Mode switch to RO CLEAN.
j.
Reset the RO Feed Tank Low Alarm.
k.
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 and caustic are added to the water.
l. Silence any alarms.
m. Set the Tank Heater switch to AUTO 2.
2. Prepare the caustic detergent cleaning solution as follows:
WARNING
Caustic chemical. Wear a protective face shield, chemical gloves, and chemical
apron when handling caustic solution. Contact with caustic will result in severe
chemical burns. Keep water ready when handling. Avoid inhaling chemical fumes.
If caustic spills, immediately flush the area with water from the auxiliary hose.
Failure to observe this warning may result in severe irritation of the nose, throat
and eyes. Contact with skin will result in severe chemical burns if not rinsed
immediately.
NOTE
Rapid pouring of detergent into the tank will cause the detergent to stick to the
tank bottom and not mix. Unmixed detergent may be drawn to the pump and
interrupt pumping.
a. Make sure a bucket of product water is placed in the operator station to rinse any area of
skin or clothing that comes in contact with caustic.
b. Hook the RO feed tank cover open.
c. VERY SLOWLY add AC-310 Membrane Detergent Cleaner into the RO feed tank as
follows:
1) Open a container of AC-310 Detergent and very slowly pour it into the RO feed
tank. Pour into the area of water flow from the mixing recirculation water flow.
2) Continue until all four of the detergent containers have been emptied.
d. Add AC-350 Caustic into the RO feed tank as follows:
1) Take one caustic container and remove the outer plastic bags.
2) Hold the container inside the RO feed tank and remove the cap.
3) Hold the container near the water (but not underwater) to avoid splashing and
slowly empty the container into the water.
4) When empty, rinse with water in the tank (now it may be held under water) then
reinstall the cap.
5) Immediately rinse the outside of the container in the bucket containing product
water before discarding.
6) Repeat until 4 containers of caustic have been added to the water in the RO feed
tank.
e. Close the RO feed tank cover.
f. Rinse the chemical gloves in the bucket containing clean water before removing.
g. After mixing, stop the RO feed pump.
h. Turn the Tank Heater Switch to OFF.
i. Set System Mode switch to STANDBY.
