The outgoing dangers of evaporative cooling plants due to bioaerosols and the resulting potential illnesses should not be underestimated by the operators.
In order to prevent this in the long term, the 42nd BImSchV (19.08.2017) stipulated concrete measures for evaporative cooling systems, cooling towers and wet scrubbers.
Detailed guidelines for implementation can be found in the guideline VDI 2047 part 2 on the following points:
- Continuous water treatment
- Instructions for disinfection
- Regular checks of microbiological, chemical and electrochemical parameters
Operators are obliged to comply with the hygiene regulations from the entry into force of the new statutory ordinance.
