TANK DISINFECTION
Storage Tank Disinfection Procedure:
1.
The storage tank can be disinfected using household bleach or a
peracetic acid disinfectant (PAA).
WARNING: Never allow Chlorine (bleach) to come into contact with PAA.
Doing so will cause a severe chemical reaction!
a.
For a 55 gallon tank, fill to the RO shut-off level mark and add 1
quart of household bleach or PAA.
b.
For a 100 gallon tank, fill to the RO shut-off level mark and add 2
quarts of household bleach or PAA.
c.
For the 185 gallon tank, fill to the RO shut-off level mark and
add 4 quarts of household bleach or PAA.
NOTE:
The values above will provide a 250 PPM concentration of
disinfectant. If desired, the disinfectant can be doubled to provide
a stronger kill (500 PPM). However, when this is done, the rinse-
up time will be significantly longer.
2.
If your system is installed with a recirculation loop back to the
storage tank, recirculate the system for 30 minutes.
3.
If your system is a demand feed (where the pump only operates
when your equipment calls for water), connect the bypass hose to
the quick disconnect and place the other end of the bypass hose
into the storage tank, recirculate for 30 minutes.
4.
After recirculation, drain the tank, fill with RO water, and recirculate
for 5 minutes.
5.
Drain, then refill the tank, and recirculate for 5 minutes. Use a
chlorine test strip to verify the residual chlorine level or a PAA test
strip to verify the residual PAA level.
6.
Repeat step 4 and 5 until the test strip indicates a residual level at
or below 1.0 ppm.
