请参考WHO指南:
4.9.9 Humidifi ers should be avoided if possible as they may become a
source of contamination (e.g. microbiological growth). Where humidifi cation
is required, this should be achieved by appropriate means such as the injection
of steam into the air stream. A product-contamination assessment should be
done to determine whether pure or clean steam is required for the purposes
of humidifi cation.
4.9.10 Where steam humidifi ers are used, chemicals such as corrosion
inhibitors or chelating agents, which could have a detrimental effect on
245
the product, should not be added to the boiler system. Only appropriate
additives should be added to the boiler system. |
