Abstract:
1. A system for providing a degassed ozonated liquid comprising dissolved ozone gas, the system comprising: a tank-less ozonation flow path having a liquid inlet and a liquid outlet, the ozonation flow path further comprising: a liquid-gas mixer, in fluid communication with the liquid inlet, to mix an accepted liquid with gaseous ozone to produce an ozonated liquid which comprises bubbles of undissolved ozone gas; and a gas-liquid separator, in fluid communication with the liquid-gas mixer, to separate the ozonated liquid into the degassed ozonated liquid and separated gaseous ozone, the gas-liquid separator comprising: a tubular member; a gaseous liquid inlet for entry of the ozonated liquid; a gas outlet arranged to vent the separated gaseous ozone out of the gas-liquid separator; a liquid outlet for egress of the degassed ozonated liquid from the gas-liquid separator; and a separating mixer secured to the tubular member and arranged to direct the flow of the degassed ozonated liquid towards the liquid outlet and to direct the separated gaseous ozone away from the liquid outlet; the liquid inlet arranged to continuously accept a substantially unozonated liquid into the ozonation flow path at a desired flow rate; the liquid outlet arranged to dispense the degassed ozonated liquid out of the system, the degassed ozonated liquid having an oxidation-reduction potential of at least 450 mV due solely to ozone dissolved in the liquid, the liquid outlet being in fluid communication with the liquid inlet and arranged to dispense the degassed ozonated liquid out of the system at the desired flow rate; the tank-less ozonation flow path adapted to ozonate the accepted liquid, producing the degassed ozonated liquid to be dispensed out of the system, the accepted liquid having a fluid residence time in the ozonation flow path of less than 5 minutes prior to dispensing as the degassed ozonated liquid.
