FIELD: saving of raw materials, environmental control, production of pure water. SUBSTANCE: method of purification of technological water coming from intake includes determination of concentration of pollution in it, its passing through filters and electromagnetic field. Processes of filtration and electromagnetic treatment are time-integrated and flow of liquid is subjected to action of electromagnetic field of infralow frequency. Gear for implementation of method has source of water intake, indicators determining degree of pollution and purification, filters for water purification and induction coils for magnetic treatment of water. Induction coils are put on body of filter and are connected to source providing for formation of electromagnetic pulse field of infralow frequency. EFFECT: decreased energy consumption, simplification of process with achievement of high degree of purification of technological water. 4 cl, 2 dwg
