Abstract: The present invention relates to a system and method of waste water treatment. In a preferred embodiment of the invention, the system comprises a frame, a pump supported in the frame for directing a portion of the waste water slurry stored within a treatment tank to an aerator apparatus effective for injecting reactive gas, such as air or oxygen, into the waste water to form an activated slurry, and out through a nozzle for introducing and directing the activated slurry into the waste water. Preferably, the activated slurry is ejected into the waste water in such a manner as to cause a circulatory flow of waste water within the treatment tank and for reducing the tendency of sedimentation of solids along the bottom of the treatment tank.

Abstract: A load monitoring, indicating, and alarm system monitors electrical continuity through an AC electrical load coupled in a first electrical line with an electrical indicator such as an indicating lamp in a second electrical line coupled in parallel with the first electrical line. A first AC electronic switch such as a triac is coupled in series with the indicator in the second electrical line. The actuating gate of the first AC electronic switch is coupled to the first electrical line. The first AC electronic switch is therefore conducting and the indicator lamp on when there is electrical continuity through the load and power is being supplied to the load. A reactance control component is coupled in series with the load for adjusting the phase angle of gate current to voltage delivered to the gate terminal of the first AC electronic switch. The reactive component may be a second AC electronic switch coupled in series with the electrical load in the first electrical line.
