<p>A water treatment apparatus is operated by providing water to be treated in a reactor; passing air through a gas wherein the passage of the air through the ozone generator produces ozone enriched air, and subsequently introducing the ozone enriched air into the reactor from the gas flow passage; providing an electric current source for powering the ozone generator; providing a member to emit a signal (preferably a visible signal) representative of the level of current drawn by the ozone generator; and, using a sensor to monitor the signal produced by the member.</p> |
