Disinfection is complete. Pull an AAMI sample.

If the MRO was disconnected during disinfection from the loop or storage tank, it can be
reconnected for use once it is producing water within the acceptable conductivity range.
WARNING: The PAA Container PAA tubing must remain disconnected from the PAA
connection on the front of the RO+ during patient treatment!
WARNING:
Although it is a necessity to use a carbon filter to remove chlorine and
chloramines from the incoming water, the carbon filter that is up-stream of
the MRO, is a potential source of bacteria. It is very important that
backwashing carbons be frequently backwashed and that the MRO is put
into fast flush for 5 minutes, minimum, before every use to minimize the
bacteria growth. An MRO that seems to be quickly re-infected after a
thorough disinfection procedure may be getting re-infected from an
insufficiently flushed carbon filter.

DISINFECTING AN MRO AND
“LARGE” LOOP SYSTEM
Disinfecting an MRO connected to a “large” loop system requires a different procedure.
Rather than using the
“DISINFECT”
mode, the
“‘CIP”
(Clean In Place) mode will have
to be accessed to assure complete circulation of the PAA through the MRO, through the
large direct feed loop, and back to the MRO.
WARNING: Circulate the PAA solution only enough to achieve a minimum
required amount of 0.5% at each water outlet in the loop system, and
at the Product Recovery water return to the CIP2 tank. Once the
minimum amount is achieved at all points, stop the circulation, and
allow the PAA solution to soak in the system.
Note: The purposes of disinfecting and cleaning are distinctly different. With
disinfection, exposure only to the disinfectant is required to destroy harmful
bacteria. On the other hand, cleaning requires exposure by recirculation to
chemically react and dissolve bio-film and/or mineral deposits that only can be
removed by continuous re-exposure of the surfaces to the active chemicals that
are in
the cleaning solutions. Therefore, the MRO during “CIP” will continuously
re-circulate and heat the chemicals (by the pumping action) through the CIP2
attachment until the procedure is stopped by direct intervention of the operator.
This is good for cleaning, but great care must be exercised for disinfection.
1.
To clean an MRO an AmeriWater CIP2 cleaning system is required to be connected to
the MRO.
2.
Follow the instructions provided in the CIP2 system manual.
