A wastewater treatment method using the device is also provided herein.

Various embodiments of the present technology provide methods and systems for soil enrichment. The systems may comprise a bioreactor system coupled to an initial treatment system for the cultivation of a live microorganism culture containing organic nutrients on an agriculturally effective scale. The systems may be automated and/or portable for practical applications onto target fields. The live microorganism culture may be delivered onto the soil of the target fields, enriching the soil with the organic nutrients that become bioavailable to crops growing in the soil. The soil enrichment system may provide a sustainable approach to agriculture that may efficiently enhance the natural processes of the native soil of any crop.

An ozone sparkling water supply apparatus includes a water supply and an ozone generator, wherein the ozone generator is communicated with the water supply via a first pipe. The ozone generator includes a main processor, a sensor electrically connected to the main processor and a fluid pressure switch communicated with the main processor via a second pipe, wherein the sensor and the fluid pressure switch correspond to each other. The fluid pressure switch starts the ozone generator for providing ozone into the water supply such that the water supply is capable of providing ozone sparkling water when the ozone is mixed into the water in the water supply.

An ozone faucet switching structure includes a faucet body, a connecting member connected with the faucet body, an aerator mounted in the connecting member, and a control sleeve mounted on the connecting member. The faucet body has a water outlet pipe which is provided with a conduit which is externally connected with an ozone device. Thus, the control sleeve is movable on the connecting member to stop supply of the ozone when not in use to prevent the ozone from being mixed with the drinking water.

An ozone water production device (1) includes: flow rate controllers (4, 5) that each control a flow rate of gas which is a raw material; a flow rate meter (12) that measures a flow rate of water which is a raw material; a booster pump (13) that controls pressure of the water; an ozone water generating unit (8) that generates ozone water by mixing ozone gas and the water; and a pressure sensor (17) that measures pressure of the ozone water which is to be supplied to a use point (19). The booster pump (13) controls the pressure of the water such that the pressure of the ozone water measured by the pressure sensor (17) is constant. The flow rate controllers (4, 5) each control the flow rate of the gas in accordance with the flow rate of the water measured by the flow rate meter (12).

An apparatus is configured to introduce ozone into water. The apparatus includes an ozone source that is configured to provide ozone. The apparatus further includes an air pump that is operatively coupled with the ozone source to provide an air stream mixed with the ozone at a pressure greater than atmospheric pressure. The apparatus further includes an ozone distributor pneumatically coupled with the air pump to introduce the ozone-mixed air stream into the water. The ozone distributor includes a porous tube set in a tortuous configuration.

Systems and methods for creating an oxidation reduction potential (ORP) in water for pathogenic control are described. The systems and methods generate an oxidation reduction potential that provides pathogenic control of the solution as well as pathogenic control of the surfaces with which the solution comes in immediate contact. The system also provides purified drinking water to a tap or an ice making machine.

A water treatment system includes a water tank, a water filtration media, and an ozone gas source. A control system operates a service mode of the water treatment system during which an external water source is filtered by the filtration media. The control system also operates a regeneration mode of the water treatment system for regenerating the filtration media. The regeneration mode includes a first backwash mode to backwash the filtration media with the external water source. The regeneration mode includes a draw mode subsequent to the first backwash mode to draw ozone into the water tank and into contact with the filtration media. The regeneration mode includes a second backwash mode subsequent to the draw mode to expel ozone from the water tank and the filtration media prior to switching the system back into the service mode for filtration of the water source with the regenerated filtration media.

A water treatment system can generate ozonated water using a vacuum operated injector with reduced vacuum switch lockup. The water treatment system includes an ozone generator, an ozone injector, a vacuum switch, and a pressure regulator. The ozone generator is configured to generate ozone. The ozone injector is coupled to the ozone generator via a hermetically sealed tubing, and the ozone injector is configured to inject the ozone into a water flow passing through the ozone injector. The vacuum switch is configured to operate the ozone generator based on a gaseous pressure inside the hermetically sealed tubing generated by the ozone injector. The pressure regulator is configured to regulate the gaseous pressure inside the hermetically sealed tubing to prevent the vacuum switch from trapped in a triggered state after the water flow stops.

Technologies (e.g., devices, systems and methods) for sanitizing reservoirs are described. In some embodiments, the technologies include a sanitization gas system and a connector unit or a hole in the reservoir wall, configured to connect a supply line to the reservoir. The connector unit may include an inlet passageway for supplying sanitizing gas (e.g., ozone) into the reservoir.
