EN The amount of wastewater discharged in Poland is constantly increasing. Although wastewater is subjected to purification processes, it constitutes the habitat of many microorganisms, including pathogenic bacteria, which infiltrate into the environment and may pose a biological threat. The purpose of this paper was to explore the possibility of using a low-frequency ultrasound to disintegrate the microorganisms found in the treated wastewater. The paper presents the research on the use of ultrasound with a frequency of 20 and 40 kHz, with variable and constant operation mode of an ultrasonic cleaner, to destroy the bacteria of the Sarcina genus. The results obtained indicate the effective action of ultrasonic waves in relation to the microorganisms studied. Already a 5-minute exposure to ultrasound at a frequency of 20 kHz with a continuous operation mode of the device reduced the number of bacteria by over 60%. The 30-minute operation of 40 kHz ultrasonic waves resulted in 80% decrease in the number of microorganisms, compared to the control. The obtained results prove the possibility of using the ultrasonic disintegration process in municipal wastewater treatment plants.
