Method for removing impurities from water and a device for carrying out said method

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.

A water purification device, comprising:

• a cylindrical mixing chamber for mixing a current of purified water with air;
• an air supply pipe supplying the air to a center of cylindrical mixing chamber;
• a container for collecting undissolved impurities;
• an output for purified water;
• wherein the cylindrical mixing chamber includes a cover plate having the air supply pipe through its center;
• the cylindrical mixing chamber being divided into an upper mass-exchange chamber and a lower mass-exchange chamber by at least one dividing wall;
• the dividing wall having a coaxial orifice towards the air supply pipe and a peripheral bypass channel;
• the lower mass-exchange chamber being formed in a lower part of the cylindrical mixing chamber and having at least two tangential branch pipes for supplying purified water into the cylindrical mixing chamber and for swirling of the water current;
• the dividing wall having peripheral bypass channels for bypassing of the undissolved impurities from the upper mass-exchange chamber,
• a side surface of the upper mass-exchange chamber having a permeable wall for outputting purified water;
• the lower mass-exchange chamber having a branch pipe for outputting of the undissolved impurities and a branch pipe for outputting clean water;
• and
• the upper mass-exchange chamber having a branch pipe outputting air.
