Claims (8)

1. A water treatment method in which the water to be treated is released into a tank (2) and air is introduced through a diffuser port (14) located near the bottom of the tank to produce bubbles of varying sizes that carry impurities in the water to the surface (15) and circulate the water in the tank in a first stream (A) out of the diffuser port, and the bubbles and contaminants are removed, causing a second stream (B) of water to circulate around the tank (2). The circulating streams (A,B) concentrate the bubbles and contaminants on the water surface in the periphery (S) direction, where the bubbles and contaminants act to form a stable compound called the bubble mixture and are removed from the tank at one or more points in the periphery direction. 2. The method under claim 1 involves removing the foam mixture from the peripheral flow direction by suction. 3. The method under claim 1 or 2, where the foam mixture is separated as it moves through a pipe to form a thin sediment from which water is removed, involves returning the water to the basin, separated from an adjacent water removal container. 4. The water treatment device consists of a basin (2) for the water to be treated, a diffuser channel (14) located at the bottom of the basin and designed to produce air bubbles of varying sizes to draw impurities out of the water through the surface, and a first circulation stream (A) of water in the basin in the direction out of the diffuser channel, and a channel (18) for removing the contaminants and bubbles that have formed on the water surface (15). The effect of the air bubble diffuser is characterized by a flow generator (16) located in the basin (2) and modified to circulate a second circulation stream (B) surrounding the basin. The two circulation streams (A,B) form an periphery flow direction (S) in which the bubbles and mixtures on the water surface (15) are concentrated, and the aforementioned channel (18) for removing the bubbles and mixtures located at one or more points along the periphery flow direction (S). 5. The instrument under claim 4, in which a rectangular basin with side walls (4) and end walls (6) is characterized by an inner wall (8) located midway between the side walls (4) of the basin, which will form a channel along the circumference (10) in the basin, such flow generators are located in the opening (15) in the inner wall near the end wall (6), and the diffuser channel (14) is located along the inner wall (8). 6. The instrument under claim 4, in which the basin (2') has a circular wall (4') with a diffuser channel (14') located in the center at the bottom of the basin, while the flow generator (16') is located on the outer wall of the basin. 7. The instrument under any of the claims in Sections 4-6 has the characteristics of a foam remover (18) in the form of a suction port (20) attached to a vacuum source (30). 8. The device according to claims 5 and 6 has the characteristics of an immediate (20) suction channel surrounded by (24) that is modified to direct the foam mixture to the suction channel.
