Abstract: front page image
(EN)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 (14) supported in an upright position having a bell-shaped member (16) attached to one end forming a chamber (28) between the inside of the tube (14) and the outside of the bell-shaped member (16). The chamber is enclosed by a ring (26) 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 (28) and discharged into the interior of the tube (16) through a plurality of apertures (30) in the ring (26) closing the chamber. A cone (34) mounted on a base plate (38) is positioned beneath the entrance of the bell-shaped member (16) 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 the bell-shaped member up and out through the upper end of the hollow tube.
