The article presents pilot research on the use of ultrasound during pressure filter backwashing to improve the efficiency of removing impurities from the surface of grains. Ultrasound is widely used in various fields for removing impurities, breaking or crushing. A low-frequency ultrasonic cleaning method was used to remove accumulated iron hydroxide deposits from the catalytic mass grains; this method did not remove manganese from the water. As the preliminary research has shown, the method gives satisfactory results. An improvement in manganese removal efficiency of around 40% was obtained.
