5.9 Sanitizing Using a CIP System
WARNING:
Determination of microbial culturing and disinfection frequency is the
responsibility of the operating facility. Failure to conduct timely microbial
culturing and disinfection could pose a risk of serious injury or death to
hemodialysis patients.
CAUTION:
RO units must be rinsed to drain under normal pressures for a minimum of
one (1) hour before exposing membranes to Minncare
®
and a minimum of
six (6) hours before exposing membranes to formaldehyde or irreversible
damage may occur. This includes start-up of machines with new
membranes.
WARNING:
Follow all MSDS precautions and OSHA standards when introducing a
chemical (i.e., cleaning and sanitizing agents).
Sanitizing frequency may be reduced by running the machine
continuously. If the machine must be turned off for more than 4 hours, it
should be programmed to flush to drain for 15 minutes every 4 hours. This
should minimize the accumulation of bacteria onto membrane surfaces.
An AUTO-ON period can be set in the Timer Menu (03) of the ECM- 100
to minimize the potential of water from becoming stagnate.
NOTE:
The Pretreatment Lockout and Tank Level Full signals will override the
AUTO-ON feature.
Performing a regularly scheduled sanitizing procedure for the machine
may be required to control bacterial growth. The machine must be cleaned
and pre-filters changed prior to sanitizing for greatest effectiveness. A 1%
peracetic acid-based disinfectant, or 0.5% formaldehyde is typically used.
Peracetic acid-based sanitizers are oxidants, and PA membranes are
sensitive to oxidants. The presence of transitional metals such as iron on
the membrane will catalyze this oxidation reaction, leading to rapid
membrane performance degradation. The use of peracetic acid-based
chemicals is acceptable under the following conditions:
• Prior to peracetic acid-based chemical use, the membrane is cleaned
with a low pH cleaner to free the membrane of iron and other
transitional metals.
