Abstract: Systems, devices and methods for controlling ozone output are shown and described. In one example, the disclosure is directed to an ozone output system for supplying ozone to at least one of a plurality of devices that demand ozone. The system may comprise an ozone generator arranged to provide ozone to at least one device, a pulse density modulation output, an inverter-based power delivery (IBPD) circuit, and an output control circuit (OCC).

Abstract: A process is disclosed for the elimination of perchloroethylene from the waste products of the dry cleaning solvent recycling process. The process consists of placing the solutions and objects contaminated with the perchloroethylene in a containment chamber, and adding ozone to the chamber until the perchloroethylene is eliminated from the waste products. The addition of catalysts or ultraviolet light to the process can increase the speed of elimination of the perchloroethylene. Another feature would re-circulate ozone that has escaped from the solution to improve the efficiency and reduce energy input into the process.
