Abstract: Disclosed is a process for treating waste water containing high levels of organic waste products which employs a series of chambers through which the water flows with the upstream chambers promoting anaerobic digestion of the waste products and the downstream chambers promoting aerobic digestion of the waste products. The upstream chambers are charged with a sludge preferably which, because of the conditions maintained within the chamber, has an ash-like characteristic upon being dried and does not contain high levels of water included within it. It is sometimes desirable to recharge the chamber with sludge since this sludge acts as a buffer that can digest shock loads of waste products having a high chemical oxygen demand. The chambers include water circulators which stir the water within the chambers and the downstream chambers having floating on the water surface high surface area media which carries bacteria. Preferably the water flows through the downstream aerobic chamber in a carousel-like fashion.

Abstract: Disclosed is a device for circulating water within a body of water including an inductor and an aspirator disposed inside the inductor. The inductor is partially submerged in the body of water and it has a restricted segment between two open ends. The aspirator is disclosed below the restricted segment in a predetermined position to provide enhanced circulation of water. Specifically, the aspirator provides a cone which fills the restricted segment with a mixture of air and water and the aspirator is positioned relative to the restricted segment so that the point where the cone begins to break apart is at or near this restricted segment.
