Patent ID: 7644908

Claim:
A water aeration system for introducing and mixing oxygen from the atmosphere into a body of water, comprising: an aeration pool or tank including a bottom wall and at least one side wall defining an internal volume containing a body of water of sufficient depth to create hydrostatic pressure therein; a bottom water outlet piping assembly including an upstanding water inlet end in said bottom wall positioned within said pool or tank internal volume and having a water outlet end located remote from said pool or tank and a distance vertically below said inlet end through which water under pressure is conducted from said pool or tank by gravity; and a vertically disposed air inlet piping assembly including an upstanding air inlet end positioned above the water surface in communication with the atmosphere and an air outlet end positioned within said pool or tank closely adjacent to said bottom wall and axially aligned with a longitudinal vertical axis of said water inlet end of said bottom water outlet piping assembly and vertically adjustable relative thereto for conducting air from the atmosphere into said body of water closely adjacent to said water inlet end; whereby water exiting through said water inlet end of said bottom water outlet piping assembly draws air from the atmosphere through said air inlet piping assembly and is mixed with the water exiting through said water inlet end of said water outlet piping assembly such that the exiting water becomes aerated.
