  • Ozone sensor and method for use of same in water purification system
    Patent number: 6280633
    Abstract: A liquid purification apparatus which uses ozone to purify water is disclosed. Off-gas from the purification process is passed through an ozone detector that provides an electric signal corresponding to the ozone concentration in the off-gas. The electric signal is monitored and used to control the length of the ozonation process. The detector comprises a MgO2 and CuO based ozone destroying catalyst which generates an electric potential when used to decompose ozone into oxygen.
