Abstract |
Water was taken over a period of several weeks from 4 air washers, and analysed to determine increase in microbial contamination. Regular adjunction of disinfectants (based on chlorine, aldehydes and surfactants) merely slowed up the proliferation of micro-organisms. The odour of the disinfectants invaded the premises, causing annoyance and discomfort. Far the best results were obtained by installing quartz lamps for UV irradiation of the water between the circulation pump and the air washers. Even using this method, periodic cleaning of the washer chamber (repeated at least every 2-3 weeks) is indispensable. The most effective means of preventing room air contamination by micro-organisms is to install filters at the air outlets. |
