Abstract

A pocket-size ozone generator for in-situ sterilization of water is disclosed. The pocket-size ozone generator comprises a power source, at least a supercapacitor, a switching circuit and at least a pair of electrodes. The power source is adapted for providing a reaction energy to generate ozone gas within the water to be treated. The supercapacitor is adapted for amplifying the reaction energy provided by the power source. The circuitry is adapted for controlling the supercapacitor to deliver consistent power supply to generate ozone. The electrodes are adapted for receiving the amplified reaction energy from the supercapacitor to generate ozone within the water to be treated.
