Abstract
Abstract Improved efficiencies in the treatment of a fluid such as oxygen or an oxygen containing gas by electron emission so as to produce a product such as ozone may be achieved by regulating the manner in which energy is used within a fluid treatment cell and the circuit used to power such a cell. Such a cell normally consists of two electrodes separated from one another by a dielectric layer and an air gap. The apparatus used to power such a cell preferably includes a power supply, a timing generator, transistors for releasing power from the power supply to a transformer at periodic intervals, diodes for permitting power to be reconveyed from the transformer to the power supply, an inductance either built into or associated with the secondary of the transformer, this secondary being connected across the terminals of the cell. With this circuit energy is stored in the cell and in both of the inductances as power is supplied. Such energy is used on the reversal of the polarity of the cell before power is released to the cell. This promotes efficiency in terms of the amount of power consumed per unit of power produced.
