FIELD: decontamination of drinking water, water in swimming pools, natural underground water and waste water. SUBSTANCE: liquid is treated by electromagnetic field at extremely low frequencies of 3 to 30 Hz or by electromagnetic field frequency-modulated or amplitude-modulated or phases- modulated ob oscillations of extremely low frequency range. Magnitude of magnetic induction of each field ranges from 0.5 to 50 mT and duration of action ranges from 5 to 120 min. EFFECT: possibility of treatment of considerable amount of liquid at reduced power requirements. 4 ex
