ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to aeration of bodies of water or other liquids such as ponds, lagoons, and the like.
2. Description of the Related Art
Methods and apparatus for aerating ponds, lagoons, basins, reservoirs and other bodies of water or other liquid are known in the art. Exemplary of the apparatus and methods for aerating bodies of water are disclosed in the following U.S. Pat. Nos.: 4,441,452; 4,514,343; 4,710,325; 5,320,068; 5,425,874; and 5,893,337.
It is an object of the present invention to provide a method and apparatus for raising the dissolved oxygen level of a body of water or other liquid.
It is an additional object of the invention to provide a method and apparatus for increasing the movement of the liquid in a body of water or other liquid.
It is a further object of the invention to provide a method and apparatus for removing hydrogen sulfide gas, nitrogen, ammonia, carbon dioxide, and methane gas from a body of water or other liquid.
SUMMARY OF THE INVENTION
A method and apparatus for aerating ponds, lagoons, basins, reservoirs and other bodies of water and other liquids. The method and apparatus of the invention may be used in water treatment, waste water treatment, industrial applications, aquaculture, and agricultural applications. The method and apparatus of the invention raises the amount of dissolved oxygen in a body of water or other liquid, increases the water movement in the body of water or other liquid, and removes hydrogen sulfide gas, nitrogen, ammonia, carbon dioxide, methane gas and other from a body of water or other liquid in which the invention is employed.
The present invention includes pumping liquids to be aerated into a hollow manifold, providing nozzles on the manifold and openings in the top of the manifold for spraying the liquids to be aerated therefrom, swirling the liquids in a spiral direction prior to the liquids reaching the nozzles, injecting air under pressure into the nozzles prior to discharge of the liquids to be aerated from the nozzles, and discharging the liquids through the nozzles and the openings from the interior of the manifold to the exterior of the manifold.
