A novel cell for generating ozonated water, the cell comprises a nafion membrane separating a diamond coated anode, and a gold surfaced cathode enclosed within a cell housing with the catalyst side of the nafion membrane facing the cathode. The cell housing has a cathode housing portion and an anode housing portion separated by the membrane, each housing portion having ridges to enhance substantially even flow of fluid over the cathode and anode. The housing portions contain O-rings in grooves to prevent leaks, and alignment features to keep the electrodes aligned. The cathode and anode have an array of holes allowing fluid to penetrate to the surface of the niobium membrane. Input ports allow fluid to flow into the housing and over the anode and cathode and then out of the housing through outlet ports. The housing may also incorporate an integrated spectral photometer including a bubble trap.

An illustrative expendable or reconstructable ozone generator cartridge for an aqueous ozone delivery device, for example, for antimicrobial sanitizing and/or medical treatment, includes a housing for a water treatment manifold providing parallel and operably fixed water pathways through ozone generating cells coupled to the manifold, and optionally a data logging and authentication feature.

An illustrative expendable or reconstructable ozone generator cartridge for an aqueous ozone delivery device, for example, for antimicrobial sanitizing and/or medical treatment, includes a housing for a water ozonating manifold, at least one ozone generating cell coupled to the manifold, and optionally a data logging and authentication feature. Advantageously, a water inlet and aqueous ozone outlet of the ozone generator cartridge is pluggable into and unpluggable from a docking station of the aqueous ozone delivery device, for example, a hand or implement washing and sanitizing device or a medical treatment device.

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 removably 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.

An ozone generation system which is adaptable for supplying ozone to different medium and small application processes. The system has a source of feed gas, a corona discharge cell receiving the feed gas from the feed gas source and generating ozone for the application process, a flow controller measuring and managing the flow of the feed gas from the feed gas source to the corona discharge cell; and a regulator receiving gas from the corona discharge cell and sending the gas to the application process. The regulator maintains pressure in the corona discharge cell independent of the application process pressure.

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 and apparatus for delivering sanitized drinking water to a poultry or other animal husbandry facility with water supplied from either a potable or non-potable source. In the case of a non-potable water source, ozone and antimicrobial copper or copper alloy are employed as primary and secondary sanitizing agents to eliminate chemical and biological drinking water contaminants. Ozone gas is generated onsite and serves as the primary sanitation agent prior to distribution of water to nipple drinker conduits within the facility. In the case of a potable water source, water is delivered directly to the drinking water distribution system. In either case, at least one conduit is filled with a woven mesh of antimicrobial copper to perform as a passive sanitation agent to inhibit microbial propagation and prevent development of biofilm within a nipple drinker system during periods of low flow and high temperatures. In the case of non-potable water source, as animals mature and consume more water, increasing concentrations of residual ozone clean the copper/copper alloy mesh surface and sanitize exposed nipple drinker actuator pins.

Disclosed are decoupled systems and methods for producing an oxidized liquid. The method comprises the steps of generating an ozone strong water in a mass transfer unit, mixing the ozone strong water with a process liquid in a mixing unit to form a homogeneous and gas-free mixture of the ozone strong water and the process liquid, forwarding the homogeneous and gas-free mixture to a reaction unit, and producing the oxidized liquid in the reaction unit. The method utilizes the acidic feed liquid to generate ozone dissolved in water having a higher concentration at a saturated or nearly saturated concentration compared to prior art processes at atmospheric pressure and neutral or alkaline pH.

A novel cell for generating ozonated water including an integrated ozone concentration detector. The cell comprises a nafion membrane separating a diamond coated anode, and a gold surfaced cathode enclosed within a cell housing with the catalyst side of the nafion membrane facing the cathode. The cell housing has a cathode housing portion and an anode housing portion separated by the membrane. The cathode and anode have an array of holes allowing fluid to penetrate to the surface of the niobium membrane. Ozonated water from the anode is channeled to a spectrophotometer integrated within the housing. The spectrophotometer creates a signal representative of the ozone concentration in the ozonated water which is utilized by control circuitry in a closed loop to maintain a stable target concentration. A bubble trap may be integrated within the housing through which the ozonated water passes before entering the spectrophotometer to remove bubbles form the ozonated water. Input ports allow fluid to flow into the housing and over the anode and cathode and then out of the housing through outlet ports.
