Water Treatment Systems Using Ozone-Filled Nanobubbles

A method of treating water, comprising:

• moving a volume of water from a pool, through a filter, and back to the pool, using a pump;
• adjusting a control valve located downstream relative to the pump such that a select volume of water is circulated through a circuit of elements, wherein the circuit of elements comprises:
• a pump assembly for circulating the select volume of water through the circuit of elements;
• a Venturi assembly comprising a Venturi injector in fluid communication with a gas supply that generates an ozone-rich gas, wherein the Venturi injector is sized and shaped to dissolve a variable quantity of the ozone-rich gas into the select volume of water;
• a pressure vessel assembly comprising a pressure vessel sized and shaped to retain a portion of the select volume of water under a design internal pressure and for a design duration;
• a nozzle assembly comprising a nozzle located downstream relative to the pressure vessel, wherein the nozzle is sized and shaped to generate a variable concentration of ozone-filled nanobubbles in the select volume of water;
• and
• a backflow valve located downstream relative to the nozzle for selectively generating a backflow pressure in the select volume of water,
• wherein the method comprises selectively controlling the circuit of elements using a control unit until a condition is satisfied, wherein the condition is selected from a condition group consisting of:
• a target quantity of the ozone-rich gas is dissolved into the select volume of water by the Venturi injector;
• a target concentration of ozone-filled nanobubbles is generated in the select volume of water by the nozzle;
• and
• a target net concentration of dissolved ozone is measured in the water in the pool.
