The combined effect of UV radiation and ultrasonic cavitation on saprophytic and conditionally pathogenic microflora of cold-water ultrasound

The paper considers the combined effect of ultraviolet radiation (UV) and ultrasonic cavitation (ultrasonic) as part filtration systems on representatives saprophytic conditionally pathogenic microflora water. Ultrasound examination (25 kHz) is a promising method purification in aquaculture due to possibility inactivation microorganisms agglomerates that are not exposed UV. As result study cultivated microflora, it was found UV ULTRASOUND have significant quantity quality It shown studied modes operation led decrease (at p <0.05) occurrence genus Escherchia relative control (without exposure ultrasound UV). total contamination water decreased 1.2×102 CFU/ml with 1.1×102 action ultrasound. sterilizer showed low efficiency relation Enterobacter cloacae, while CFU 0.94 ± 0.05 Log10.
