FIELD: water and air purification technology.
SUBSTANCE: invention relates to a method of reagent-free water filtration and disinfection. Method includes hydroacoustic waves of sound and ultrasonic frequency range with amplitude of acoustic pressure of not less than 104 Pa at 1 m from radiator surface in main module, in form of water intake header, in the first additional module, which is a water intake well, in the second additional module, in the form of a mixer. Processing in the third additional module, which is at least two settling tanks, is carried out by hydroacoustic waves of the sound and ultrasonic frequency range with amplitude of acoustic pressure of not less than 102 Pa at 1 m from surface of corresponding hydroacoustic radiator, treatment in a special structure, which is at least two transparent for ultraviolet irradiation water conduits, containing at least four ultraviolet lamps with hydroacoustic emitters of ultrasonic frequency range, radiation of ultraviolet light, as well as with ultrasound acoustic wave acoustic signal with amplitude of acoustic pressure of not less than 105 Pa at 1 m from hydroacoustic radiator surface with additional use of hydroacoustic waves of sound and ultrasonic frequency bands with amplitude of acoustic pressure of not less than 104 Pa at distance of 1 m from the surface of the hydroacoustic radiator buried in granular filter material in the geometric center of the bulk filter.
EFFECT: obtaining clean disinfected water in a large volume taken from surface water supply sources.
