A wastewater treatment device has: an ozone generator which supplies ozone; a mixer which mixes ozone supplied from the ozone generator with wastewater and supplies ozone mixed wastewater; an ozone oxidation unit which progresses ozone oxidation in the ozone mixed wastewater while passing the ozone mixed wastewater therethrough and discharges wastewater in which the ozone has been consumed; a biological treatment unit which performs biological treatment on the wastewater discharged from the ozone oxidation unit using microorganisms; and an adjusting device which adjusts the amount of ozone to be mixed with the wastewater by the mixer so that ozone in an amount that inhibits the microorganisms of the biological treatment unit does not remain in the wastewater discharged from the ozone oxidation unit.

An ozone water treatment system using low energy. The present invention includes: a water pipe through which raw water, to be treated, is transferred and supplied while having energy; a gas injector for dispersing and injecting, in a micro bubble form, ozone gas to the raw water supplied and transferred from the water pipe; a low-energy using-type gas-liquid contact reactor for promoting a contact reaction between the ozone gas and the raw water within ozone mixed water supplied and transferred from the gas injector; and a discharge pipe for continuously transferring and discharging treated water having been reaction-treated. Therefore, since energy use during the ozone gas injection and the contact reaction can be remarkably reduced, processing costs can be reduced.

A portable liquid filtration device includes a GPS tracking unit, a portable housing, an inlet configured to receive non-potable water, and an ozone chamber positioned within the portable housing. The ozone chamber is configured to generate an ozone gas from received air. The device also includes a filtration duct positioned within the portable housing and downstream from the inlet. The filtration duct includes at least one advanced oxidation (AO) chamber configured to mix the received water with the ozone gas, and at least one ultraviolet (UV) chamber downstream from the at least one AO chamber and including a UV lamp positioned adjacent the water within the filtration duct. The device further includes an outlet positioned on the portable housing and downstream from the filtration duct. The filtration duct is operable to output at least 400 liters per hour of the received water from the outlet as potable water.

A gas dissolving system using double mixers to generate a higher gas concentration in liquid is disclosed. The gas dissolving system includes two gas mixers, a degassing device, pressure valves, a pressure sensor, and a pump. Liquid flows through mixers to entrain gas therein, and it thus contains dissolved gas and undissolved gas. The liquid subsequently flows into the degassing device so that undissolved gas is released to the outside environment, and dissolved gas remains in the liquid. The liquid with dissolved gas combines with raw liquid and is diluted so that it becomes liquid with a desired gas concentration as the output. A high gas concentration of liquid is obtained after more cycles of fluid flow through the mixers to dissolve gas without combining raw liquid.

A wastewater treatment device has: an ozone generator which supplies ozone; a mixer which mixes ozone supplied from the ozone generator with wastewater and supplies ozone mixed wastewater; an ozone oxidation unit which progresses ozone oxidation in the ozone mixed wastewater while passing the ozone mixed wastewater therethrough and discharges wastewater in which the ozone has been consumed; a biological treatment unit which performs biological treatment on the wastewater discharged from the ozone oxidation unit using microorganisms; and an adjusting device which adjusts the amount of ozone to be mixed with the wastewater by the mixer so that ozone in an amount that inhibits the microorganisms of the biological treatment unit does not remain in the wastewater discharged from the ozone oxidation unit.

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.

A system for creating an oxidation reduction potential (ORP) in water and for reducing the surface tension of the water for the pathogenic cleansing and/or degreasing of hard surfaces and equipment. The hard surfaces to be cleansed and/or degreased may be plastic, glass, ceramic, porcelain and stainless steel. The equipment to be cleansed and/or degreased may be food service equipment such as ovens, ranges, fryers, grills, steam cookers, refrigerators, coolers, holding cabinets, cold food tables, work tables, beverage dispensing equipment, beer dispensers, shelving, food displays, dish washing equipment and grease traps.

The disclosure relates to a method of performing ozonolysis or ozone-based oxidation on a liquid or emulsified reagent using a tubular falling firm reactor with one or multiple tubes wherein the combined ozone and carrier gas flow is co-current.

Disclosed is an apparatus and an operating method for deep denitrification and toxicity reduction of wastewater. The apparatus comprises a regulation tank, an aeration biofilter, an ozone reaction tank, an ozone generation and diffusion device, and a denitrification biofilter. By the coupling reaction treatment of microorganisms, ozone, electrolysis and denitrification, an effect of refractory organic contaminants and nitrate nitrogen removal, deep denitrification and toxicity reduction can be achieved.

An apparatus for manufacturing water having a high concentration of dissolved ozone is characterized by being configured by connecting: a filtering device; a water tank connected to the filtering device; a pump connected to the water tank; a Venturi tube connected to the pump; a first gas dissolving pressure device connected to the Venturi tube; and a second gas dissolving pressure device connected to the first gas dissolving pressure device.
