3030226 Rev. D 5-13 Routine Maintenance
5.3.1 Cleaning Procedure
There are two types of cleaners available, a low pH cleaner (Calcium/Iron removal) and
a high pH cleaner (Silt/Organics removal). Mar Cor Purification provides these cleaners
in liquid form. The low pH cleaner attacks mineral scale deposits such as calcium,
magnesium and iron build-up. The high pH cleaner will remove accumulated silt and
organic matter from the RO membrane. Typically, the low pH cleaner should be used
first followed by the high pH cleaner. There may be specific fouling/scaling situations
where it will be advantageous to reverse this order of cleaning.
WARNING:
The cleaning solution is an irritant to eyes and skin. It is recommended that
protective gloves and eye protection be worn when handling the cleaner. Always
follow recommendations found in the Material Safety Data Sheet and any
applicable OSHA standards for the chemical being used.
WARNING:
Label machine with appropriate warning signs such as “DO NOT USE/CONTAINS
CLEANER” to prevent use of the RO until it is properly rinsed.
CAUTION:
The different cleaners must not be mixed together. For typical cleaning
processes, Mar Cor Purification recommends using the low pH cleaner first,
thoroughly rinse the system, and then use the high pH cleaner.
CAUTION:
Biosan™ is not intended for use in hemodialysis machines.
