Abstract
An injector-mixer for injecting and thoroughly mixing fine bubbles of air into a contaminated water stream from a fish tank is disclosed. Water is pumped down through an injection section of the present invention where air is injected into the stream by an improved Venturi construction. The mixture then flows into an improved mixing section, where it is thoroughly mixed such that the plethora of small air bubbles have a greater chance to bond with the contaminants of the water, the contaminants becoming buoyant as a result. Upon introduction of the mixture into the protein skimmer column, the bubbles of air and contaminants attached thereto rise to the top of the protein skimmer column to be contained, while the filtered and oxygenated water is returned to the tank.
