USING OF NANOFIBER FILTER FOR AIR FILTRATION IN WATER SUPPLY FACILITIES

The air is a medium that is commonly used for various water treatment methods or it is in very close touch with treated water. Untreated air can content significant amount of pollutants. Contact of polluted air with treated water causes interactions of both media which results in water contamination. Nanofiber filter has numerous prerequisites for high quality and efficiency of air treatment. Testing of nanofiber filter efficiency, analyses of proper filter type for different air filtration purposes and measure of disinfection effects was researched and compared with commonly used filter. Functionality of the filters was verified on prototype unit. The test of passive contamination corresponded to interaction in water tanks. Physical parameters such as velocity, flow, temperature and pressure difference of the filters were measured for the test. Also microbiological samples of examined filters, filtrated air and saturated water were evaluated. Analyses of measured values confirmed effectiveness of nanofiber filters in air treatment and determined advantages and borders of their application.
