FIELD: water purification. SUBSTANCE: natural or process water is purified via electocoagulation in which voltage pulse packets are applied on electrodes, pulses being amplitude-modulated and separated by pauses, whereas voltage polarity on electrodes is periodically changed by way of supplying pulses with direct and reverse polarity. EFFECT: enhanced efficiency of process. 1 dwg, 1 tbl
