12.2 Disinfection
Disinfection working steps
1. Rinse the RO system by starting standby mode.
2. Fill the supply tank with permeate.
3. Determine the system/loop volume to be disinfected (
part 1, chapter 12, table 12-1 “Disinfectant
4. Program sequence: See
5. The commercial preparation is to be provided as an approx. 2% solution for reliable water bacteria dis-
infection.
In this respect, a basic solution is used in the supply tank, where the concentration of the disinfectant
must not exceed 8% (otherwise the membrane would be damaged!). Consult LMW in the case of
proven contamination by fungi/yeast or spores.
6. The contents of the supply tank must be circulated until the concentration is the same in the loop
supply and return flow. (Aid: conductivity)
IMPORTANT LMW strongly recommends membrane cleaning prior to disinfection.
Sealing product on membrane surfaces can irreversibly damage the membrane.
NOTICE
Disinfection (or cleaning) is recorded in the respective log provided and in the medical
device log (
WARNING
Dialysis is not permitted during disinfection or cleaning.
WARNING
The warning instructions of the disinfectant or cleaning agent manufacturers must be
observed when these products are being used, and personal protective equipment must
be worn.
WARNING
Acute risk of poisoning if disinfectants or cleaning agents are taken or administered.
IMPORTANT Make sure the contents are well mixed in the supply tank, because layers can form on the
bottom of the tank due to the different specific densities of the disinfectant and permeate.
IMPORTANT Contamination in the water treatment system can lead to an unspecified disinfectant
reaction to occur which can greatly reduce the concentration of the effective disinfectant.
In certain cases, the amount of disinfectant needed can differ greatly from the calculated
requirement.
