FIELD: purification plants, particularly purification and demineralization of industrial and sea water until ecologically pure state from solid particles and chemical compounds dissolved in it, procession of separated fractions at minimum consumption of electric power. SUBSTANCE: method comprises steps of creating liquid flow in the form of helical swirl necessary for separating solid particles, subsequent separation of ion components of solution in magnetic field by action of Lorenz forces. Purifying section of pipeline includes apertural tube with helical ducts arranged in pipe for collecting and removing solid particles. Apertural tube is joined with converging tube and it has helical blades. Converging tube has helical ducts and solenoids placed on its outer surface. EFFECT: separation of liquid flow by acid, hydroxide and neutral fractions. 2 cl, 1 dwg
