This disclosure relates to systems and methods for controlling treatment of water with ozone. The systems and methods can utilize one or more processing modules and one or more non-transitory storage modules that are configured to store computing instructions. Execution of the instructions can cause the one or more processing modules to perform acts of: generating ozone; and applying the ozone to water. The act of generating the ozone can include: controlling a quantity of the ozone generated; and controlling when the ozone is generated.

A method for electrolysis-ozone-corrosion inhibitor/electrolysis-ozone-hydrogen peroxide-corrosion inhibitor coupling treatment on toxic and refractory wastewater includes the following steps: adding toxic and refractory wastewater to be treated into a wastewater treatment reaction tank equipped with a plate anode and a plate cathode, and starting a direct current (DC) power supply connected to the plate anode and the plate cathode to treat the toxic and refractory wastewater at an appropriate current density under stirring, during which a corrosion inhibitor and hydrogen peroxide are added to the toxic and refractory wastewater to be treated and ozone is introduced into the toxic and refractory wastewater to be treated through an aeration device. The method can increase the production rate and production quantity of free radicals in a reaction system, effectively improve the treatment efficiency for toxic and refractory wastewater, and reduce the treatment cost.

A water treatment system includes an ozone generator combined with an electrolytic chlorine generator in a compact, efficient and serviceable assembly. The system may include a modular and replaceable ozone generator, which allows a damaged or non-functional ozone generator to be quickly and efficiently replaced. In order to protect the ozone generator from damage, a fail-safe drain valve assembly may also be provided which will expel backflowing pool water before it is allowed to backflow into the ozone generator. The water treatment system may further include an insulated electrolytic chlorine generator that mitigates or eliminates current leakage for efficient operation.

Sanitization edge compute devices are discussed herein. For example, an ozone generator may be controlled to output ozone in an environment to achieve a first ozone concentration level at a first time. A first decay rate of the ozone in the environment may be determined from the first ozone concentration level during a first period of time. The ozone generator may be controlled to output the ozone in the environment to a second ozone concentration level at a second time. A second decay rate of the ozone in the environment may be determined from the second ozone concentration level during a second period of time. A difference between the first decay rate and the second decay rate may be determined. An action may be performed based on the difference.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing, an ozone inlet fitting coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.

A system for generating aqueous ozone solution (AOS) is disclosed. The system includes a system enclosure and a cradle mounted within the system enclosure. The cradle has a wall that defines separate compartments within the system enclosure, including a first compartment for electronic components and a second compartment for a fluid path extending from a water inlet to an AOS outlet. The first compartment contains an ozone generator and a relay mounted to the cradle. The fluid path within the second compartment includes a fluid mixer that is coupled to the ozone generator via one or more tubes extending across (e.g., over or through) the cradle wall that separates the first and second compartments. The fluid mixer is configured to inject ozone generated by the ozone generator into water received from a water source via the water inlet to produce AOS that is output via the AOS outlet.

Increased control and efficiency over the wastewater purification can be achieved through creating conditions that allow the operator to selectively prioritize the digestive function of microorganism in the activated sludge. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is passed through an atomizer or a cavitation pump to instantly render the reactive gas to an ultra-fine bubble state. At least a portion of the ultra-fine bubbles dissolve within the gas-dispersion return sludge, activating the dormant microorganisms. Due to a complete or an almost complete absence of biodegradable material in the gas-dispersion return sludge, the microorganism prioritize their digestive function, and when exposed to biodegradable pollutants present in wastewater, digest the pollutants using biochemical pathways different from the ones used in nature.

A transportable system for generating aqueous ozone solution includes a hand truck carrying one or more auxiliary compartments containing respective mixing assemblies that are fluidically coupled to an ozone supply unit. At least one mixing assembly includes a first flow path for water to flow through and a second flow path in parallel with the first flow path. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of the ozone supply unit. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path and mixed into the water flowing through the first flow path to produce an aqueous ozone solution.
