ABSTRACT:
An aerator for aerating a body of first liquid such as a pond, waste-water site or marina. It consists of a pair of concentric elongated tubes whose lengths can vary depending on the needs of the aerator and the depth of the liquid to be aerated. Above the level of the first liquid, at least one air inlet port is secured to the upper region of the outer tube of the aerator to provide air flow in the annulus between the tubes while at least one second liquid inlet port is secured to the upper region of the inner tube for the passage of the second liquid therethrough. This second liquid and air travel along these separate flow paths within the inner tube and annulus, respectively, before reaching a mixing area in the lower end of the outer tube and adjacent a diffuser manifold positioned below the surface of the first liquid. It is within this mixing area that the second liquid and air are mixed together before this mixture exits the diffuser manifold through one or more manifold tubes to aerate the pond, waste-water site, marina, or other first liquid body in which the aerator is placed.
