Abstract:
An aeration and mixing apparatus comprising:a. a plurality of pontoons for floating said apparatus upon the surface of the liquid being aerated,b. a generally cylindrical manifold connected to said pontoons for receiving liquids to be aerated and for spraying liquids therefrom, said manifold having at least two nozzles for spraying liquids therefrom, said manifold having an air venturi tube therein for each of said nozzles, each of said air venturi tubes extending into one of said nozzles and spraying air under pressure into the liquids being discharged from said nozzle, each of said air venturi tubes having a plurality of vanes thereon which cause liquids flowing therearound to swirl in a spiral direction prior to discharge from said nozzle in which said air venturi tube is located, said manifold having a plurality of openings in the top portion thereof for spraying liquids under pressure in said manifold therethrough to the exterior of said manifold,c. a liquid pump connected to said pontoons which supplies liquids under pressure to said manifold,d. an air pump connected to said pontoons which supplies air under pressure to said air venturi tubes in said manifold, ande. a motor connected to said pontoons which drives said liquid pump and said air pump.
