Abstract:
An apparatus for treating an object with ozone, comprising:a treatment chamber for receiving the object, said treatment chamber being hermetically sealing means to provide a complete seal, said treatment chamber including an inlet for introducing an ozone-oxygen mixture therein, and an outlet for removing the ozone mixture therefrom;a supply of ozone-oxygen connected to the inlet of said treatment chamber;a suction pump connected to the outlet of said treatment chamber;a sealing check means for testing the sealing means;and a control system for controlling said ozone-oxygen supply, said suction pump to produce a negative pressure in said treatment chamber in order to prevent ozone leakage from the chamber into the atmosphere and the sealing check means to provide an indication of the condition of the seal;wherein said control system is a means for producing a static mode of operation, wherein there is no ozone flow into or out from said treatment chamber except during testing periods wherein a flow is produced through the outlet and the loss in ozone is determined and is made-up by introducing a quantity of make-up ozone via the inlet of said treatment chamber.
