GENERAL CLEANING and DISINFECTING INFORMATION
To perform at peak efficiency the Medipac RO must periodically be cleaned and disinfected, and
the Post-Treatment disinfected. These procedures are a crucial part of ensuring optimum
performance.
The
Cleaning Process
(RO Only)
is designed to remove mineral deposits that may build-up on
internal surfaces.
The
Disinfecting Process
is designed to significantly reduce bacteria and endotoxins that may
build-up in the water and on the internal surfaces in the form of bio-film. The importance of
regular and frequent disinfection cannot be minimized due to the risk associated with bacteria
proliferation.
CLEANING and DISINFECTING FREQUENCY
As the manufacturer, Better Water LLC recommends the following:
-
If membrane fouling is indicated
: Low pH Clean with BWI-1000 and Disinfection with
Minncare
-
Monthly
: Low pH Clean with BWI-1000 and Disinfection with Minncare
(in that order).
-
Quarterly
: Low pH Clean with BWI-1000, High pH Clean with BWI-2000, and
Disinfection with Minncare
(in that order).
-
If the RO has been in storage
and should have been loaded with preservative,
then after rinsing of preservative the following should be done: Low pH Clean with
BWI-1000, High pH Clean with BWI-2000, and Disinfection with Minncare
(in that order).
Cleaning and disinfecting should be initiated if membranes are fouled indicated when…
the
Product Flow decreases
and the
Reject Flow increases
, and the two cannot be
adjusted to design specifications
the
Pump Pressure increases
, the
Membrane Pressure increases
, and the
Reject
Pressure decreases
the
Quality Monitor
indicates a
continuous decline in water quality
The RO may require more frequent cleaning and disinfecting, which is ultimately the
Medical Director’s responsibility to determine and is typically based on water testing.
RESIDUAL CHEMICAL TESTING
Users should refer to the chemical agent manufacturer to determine the appropriate method for
testing for residual chemical substances in the water after cleaning and disinfecting. The water
must be clear of detectable levels of cleaning and disinfecting agents prior to use with patients
WARNING
DO NOT use “Hydrochloric Acid” based products for disinfection and/or cleaning the
RO as these can damage the internal components and will void the Limited Warranty.
Use only the recommended products as previously detailed.
Also DO NOT use “Sodium Hypochlorite” (bleach) based products as these will
damage the
RO’s membrane.
CAUTION
If performing both Low pH and High pH cleanings, always perform the Low pH first,
otherwise the membrane can be damaged.
