Abstract
A water treating or aeration device for transferring gases to a liquid such as used for waste water treatment. The aeration device is comprised of an elongate hollow tube supported in an upright position having a bell-shaped member attached to one end forming a chamber between the inside of the tube and the outside of the bell-shaped member. The chamber is enclosed by a ring attached to the bell-shaped member and flaring outwardly into abutment with the inside of the tube. A gas, such as air, is supplied to the chamber and discharged into the interior of the tube through a plurality of apertures in the ring closing said chamber. A cone mounted on a base plate is positioned beneath the entrance of the bell-shaped member and secured to the aeration device or tube by a plurality of adjustable legs. Air introduced into the chamber is discharged through the apertures drawing fluid in a swirling motion through said bell-shaped member up and out through the upper end of the hollow tube.
