Abstract
A sealed multi-chambered bag, that is a flexible container, is made of dielectric material and contains two electrode plates (preferably screen plates) that are separated by an internal wall of the bag. Materials to be sterilized are placed between one or the other or both of the electrode plates and the interior wall. The interior wall allows the plates to be contained within the bag without the risk of damaging high voltage discharges occurring between plates optimal ozone production occurs in the bag immediately adjacent to where the materials to be sterilized are located. The bag is placed within a chamber containing an aperture which is connected to the intake of a pump. A conductor connects each electrode plate to an opposed terminal of a high tension transformer. Both the pump and the transformer are connected to timing circuitry, which turns on the pump and the transformer and, then periodically turns the pump off and on to deflate and re-inflate the chambered bag and circulates the ozone produced therein to all virulence on the materials being sterilized. The gas within the bag alternatively expands and compresses before the transformer is turned off. The timer circuit all…
