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.

In a water treatment system, in particular for cooling towers, comprising a fluid basin and a circulation circuit designed to draw a fluid from the fluid basin and subsequently return it again, the circulation circuit comprising an ozone supply device for introducing ozone into the fluid, it is provided that the ozone supply device comprises a swirl chamber reactor and an ozone generator, which is connected to a filter system having an inlet opening for ambient air such that ambient air cleaned by the filter system, in particular substantially pure oxygen, can be fed to the ozone generator for ozone generation.

A waste treatment system including at least one treatment chamber through which a fluid to be treated is moved in a fluid flow, the or each treatment chamber including at least one of a number of ultraviolet light sources, and at least one dispersion assembly located at a base of the treatment chamber to disperse at least one sterilizing agent supplied to the treatment chamber in a counter flow direction to the fluid flow.

Disclosed are systems and methods for mixing a gas-free liquid oxidant with a process liquid to form a homogeneous and gas-free mixture with minimized degassing. The mixing system comprises an injection device, integrating with a pipe through which a process liquid flows, configured and adapted to inject a gas-free liquid oxidant into the process liquid, and a mixer, fluidly connected to the pipe and the injection device, configured and adapted to mix the process liquid and the gas-free liquid oxidant therein to form a homogeneous and gas-free mixture of the process liquid and the gas-free liquid oxidant with minimal degassing. The method comprises the steps of a). injecting the gas-free liquid oxidant into the process liquid, and b). mixing the gas-free liquid oxidant and the process liquid to form the homogeneous and gas-free mixture. The gas-free liquid oxidant is ozone strong water.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump or a line atomizer. A compressor can be introduced at an inlet of the cavitation pump or the line atomizer, compressing the gas mixture at a pressure higher than the pressure within pump or the atomizer. The compressed gases are provided to the inlet of the atomizer or the pump, where the compressed gases mix with the water and enter the cavitation pump or the line atomizer (where most of the dissolution of the gases happens). The compressor allows to increase the amount of oxygen and ozone provided to the pump or the line atomizer, increasing their dissolved concentration. In addition to the disinfecting properties, the higher level of oxygen correlates to an improved taste of the water.

A system for creating an oxidation reduction potential (ORP) in water employs a manifold. The manifold includes an enclosure containing a plurality of fluid paths and having one or more ozone intake ports. The ozone intake ports are fluidically coupled to one or more ozone output ports of an ozone supply unit housed in a separate enclosure. A plurality of flow switches are disposed within the enclosure and configured to transmit control signals to one or more controllers of the ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply unit to generate ozone. A plurality of fluid mixers are also disposed within the enclosure. The fluid mixers are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply unit into the water flowing through the fluid paths.

A sanitizer system has an ultraviolet (UV) lamp, a UV transparent tube and Venturis that that draw ozonated air from near the UV lamp and mix the ozonated air with water traveling through the UV transparent tube while UV light breaks down ozone in the UV transparent tube into free radicals and other ozone decomposition products. Additional ozone can be introduced into what after it passes through the UV transparent tube.

An automated produced water treatment system that injects ozone or an ozone-oxygen mixture upstream of produced water separators, with the dose rate changing dynamically as the produced water quality changes, as determined by continuous monitoring of the produced water quality by a plurality of sensors that detect water quality parameters in real time. The system may operate as a “slipstream” injection system, that draws a portion of produced water from the produced water pipeline and injects ozone or an ozone-oxygen mixture back into the pipeline with disrupting or slowing normal operations. Disinfectants or other additives may also be injected. The treatment system may be wholly or partially contained in mobile containers or trailers, for on-the-fly use in existing produced water treatment facilities.

An ozone water supply apparatus and an ozone supply device are provided. The ozone generation device includes a Venturi tube and an ozone generation module connected to the Venturi tube. The ozone generation module includes a circuit unit, an ozone-activated tube, and a launcher, the latter two of which are electrically coupled to the circuit unit. The launcher includes a transparent tube, a floating body arranged in the transparent tube, and an optical detector arranged outside of the transparent tube and electrically coupled to the circuit unit. When a gas flows through the transparent tube so as to move the floating body along the transparent tube, the optical detector is configured to detect the movement of the floating body, so that the ozone-activated tube can be driven by the circuit unit to excite the gas to become an ozone that floats toward the Venturi tube.

A system and method for creating an oxidation reduction potential (ORP) in water and for reducing the surface tension of the water for the microbiological decontamination of food animal carcasses. A method is also described for the microbiological decontamination of beef trimmings.
