FIELD: purification of sewage waters from harmful impurities; applicable in various industries. SUBSTANCE: device includes aeration chamber accommodating jet-type air dispersers, chamber of acceleration of gas-liquid flow velocity, branch pipes for introduction of gas, solution of reagents and additional liquid, hydraulic nozzle with holes made on side of pipeline of ready activated gas-liquid mixture. EFFECT: higher efficiency and flotation activity of mixture of water, air and reagents due to creation of conditions of formation of boundary adsorption layer of surfactants on bubble surface. 2 cl, 1 dwg
