Abstract:
A method of treating water with ozone in a household water treatment apparatus comprises providing water to be treated in a reactor and current to an ozone generator; using a water pump to circulate at least a portion of the water to be treated through a fluid flow path and a venturi; using the passage of water through a venturi provided in the fluid flow path to draw air through a gas flow path which includes an ozone generator wherein the passage of the air through the ozone generator produces ozone enriched air, and subsequently drawing the ozone enriched air into the fluid flow path from the gas flow passage; monitoring the rate of flow of air through the gas flow passage; monitoring the current drawn by the ozone generator; and, terminating the treatment if one or both the rate of flow of air and the current drawn by the ozone generator vary from preset values.
