Title (EN) WATER TREATING DEVICE
(FR) DISPOSITIF DE TRAITEMENT DES EAUX
Abstract:
(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.
(FR) Un dispositif de traitement ou d"aeration des eaux pour transferer des gaz dans un liquide tel que ceux utilises pour le traitement des eaux usees. Le dispositif d"aeration comprend un tube allonge (14) tenu en position verticale ayant un element en forme de cloche (16) fixe a une extremite forant une chambre (28) entre l"interieur du tube (14) et l"exterieur de l"element en forme de cloche (16). La chambre 800 est fermee par un anneau (26) fixe a l"element en forme de cloche et evase vers l"exterieur jusqu"a buter contre l"interieur du tube. Un gaz, tel que de l"air, est amene dans la chambre (28) et decharge a l"interieur du tube (16) a travers une pluralite d"orifices (30) amenages dans l"anneau (26) fermant la chambre. Un cone (34) monte sur une embase (38) est positionne sous l"entree de l"element en forme de cloche (16) et assujetti au dispositif d"aeration ou tube par une pluralite de pattes reglables. De l"air introduit dans la chambre est refoule a travers les orifices amenant le fluide en un mouvement de tourbillonnement a travers l"element en forme de cloche vers le haut et l"exterieur par l"extremite superieure du tube creux.
