The article presents the results of experimental studies of water cleaning from metal ions by combined method which includes the electrochemical treatment by alternating current and simultaneous air bubbling followed by coagulation and settling. The highest degree of water cleaning from all considered metal ions is achieved by passing through water to be cleaned the asymmetrical alternating current using dissimilar insoluble electrodes (stainless steel 12X18H10T, titanium alloys ОТ 4-0) at air bubbling, introducing coagulant – ferrous sulfate FeSO4•7H2O with the initial ratio of concentration complex forming ion and exhaust ion 5:1 and water settling for 8 days.
