Abstract:
A system for supplying ozone to a liquid containing a detergent for removing a contaminant from the detergent to facilitate cleansing and reuse of the detergent, the system comprising:an ozone generator for generating ozone; a reservoir for containing a quantity of the liquid containing the detergent; a venturi for injecting the liquid containing the detergent with the generated ozone, the venturi having an inlet and an outlet with an orifice being located between the inlet and the outlet, and the ozone generator being coupled to the orifice for supplying the generated ozone thereto; a pump, coupled to an outlet of the reservoir and to the inlet of the venturi, for pumping the liquid containing the detergent from the reservoir to the venturi; the outlet of the venturi being connected to a return inlet of the reservoir for supplying the liquid containing the detergent and ozone back to the reservoir in a turbulent manner; and a mixing chamber coupling the outlet of the venturi to the return inlet of the reservoir, and the mixing chamber causing sufficient mixing of the ozone supplied to the liquid containing the detergent so as to facilitate substantially complete dissolving of any ozone bubbles and ozone pockets within the liquid containing the detergent to form a substantially uniform mixture of an ozonated liquid with the percentage of ozone in contact with the liquid containing the detergent to be in excess of about 60%.
