An air injector assembly has an input port and an output port connected by a bypass bore and tapered bore. Fitted within the tapered bore is an air injector mechanism which contains a throat and a venturi nozzle portion. The opening of the bypass bore can be varied so that the amount of water passing therethrough is controlled to regulate the pressure being received at the input port which represents the back pressure on a pump. By varying the opening of the bypass bore, the back pressure of the pump can be regulated so that the pump may operate safely. Air is injected into the air injector assembly when water is pushed through the throat and into the venturi nozzle. A cavity is formed at the junction where the throat is coupled to the venturi nozzle so that air can be drawn thereat to aerate and oxidize the water passing therethrough. By aerating and oxidizing the water, hydrogen sulfide is removed and iron is precipitated, and can be removed later. An air supply assembly provides a safety valve which only allows air to be drawn into the air injector assembly.

Apparatus for oxidizing a fluid, comprising: a member through which the fluid traverses having input and output ports for receiving and outputting the fluid respectively; two bores each connecting said input and output ports to provide respective passageways through said member; means adapted to one of said bores for injecting air to the fluid traversing through said member; and comprising a unitary adjustable means having a portion thereof movable within the other of said bores for varying the opening of said other bore to control the amount of fluid traversing therethrough to thereby regulate the pressure of the fluid traversing through said member and effect said air injecting means to inject an appropriate amount of air to the fluid traversing through said member to ensure that adequate oxidation of the fluid takes place.
