Air humidifiers using cold water and cooling towers of air-conditioning systems provide the best settings for the growth of bacteria.
Hence, we investigated 90 water samples from humidifiers and 15 water samples from cooling towers of hospitals, authorities, schools, and factories.
The colony forming units/ml at 20°C and 36°C, the biological activity of added biocidal substances, and the occurrence of legionella were determined.
About 90 percent of the samples showed no activity of the biocidal substance added, suggesting the uselessness of such substances.
Furthermore, they exercised neither an influence on the CFU of the water samples nor on the occurrence of legionella.
