Abstract
This invention relates to cylindrical liquid conditioning and settling tank having rotating conditioning arms. On the wall of the tank are narrow, inwardly directed parallel vanes that are inclined to the vertical and that serve to separate the tank into a lower water conditioning zone in which the water is turbulent and an upper water-solid separation zone in which the water is quiescent. At least one nozzle is provided to supply water into the tank below the vanes in a direction tangential to the tank wall.
Claims7
A liquid conditioning and settling tank comprising a base, a cylindrical wall surrounding the base, a series of spaced vanes located about the cylindrical wall and projecting radially inwardly from the wall a portion of the way up the wall, means for feeding liquid to be treated into a lower portion of the tank, means to rotate the liquid circumferentially in the tank below the vanes in a predetermined direction, and velocity reducing take-off means for removing from the tank treated liquid at the upper surface of the liquid, the vanes being inclined from the vertical in the direction of rotation of the liquid and having exposed lower edges whereby the rotating liquid impinging on the vanes is deflected downward with substantially no upward component, said means to rotate the liquid comprising an inlet projecting through the wall below the inclined vanes and directed tangentially of the wall.
