Abstract:
1. A method of water purification from impurities, the method comprising: supplying purified water into the cylindrical mixing chamber; swirling a water current of the purified water; supplying air through an air supply pipe along an axis of the cylindrical mixing chamber to oxygenate the purified water; outputting water and undissolvable impurities from the cylindrical mixing chamber; generating a standing acoustic wave in the cylindrical mixing chamber wherein the cylindrical mixing chamber is divided into an upper mass-exchange chamber and a lower mass-exchange chamber by a dividing wall that has a coaxial orifice towards the air supply pipe and a peripheral bypass channel for the air supply and water cross-flow, wherein the water current is swirled in the lower mass-exchange chamber at the preset speed in the peripheral part in order to create a negative pressure along the central axis of the cylindrical mixing chamber, atmosphere air intake and creating of two countercurrents of water in the lower and upper mass-exchange chambers, the countercurrents interacting with each other to thereby generate the standing wave and simultaneously oxygenate of the water current; outputting insoluble impurities formed in the water current and accumulated in the peripheral swirl current from the cylindrical mixing chamber through a permeable wall on the side surface of the upper mass-exchange chamber.
