A portable, personal apparatus for treating drinking water comprises a generally tubular or cylindrical filter housing containing filtration media and water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter. The design of the apparatus involves the bottle exterior and interior contouring to the filter and enables the efficient and rapid gravity flow of water in through the filter. The apparatus may be configured such that water is first passed through a top reservoir designed to receive water, followed by a porous mesh, followed by granular filtration and antimicrobial media agitated by turbulent motion of influent water, followed by a porous mesh before reaching a durable and reusable water containment vessel.

A portable water bottle includes a water bottle body having water stored therein; and a sterilizing module for irradiating the inside of the water bottle body with sterilizing ultraviolet rays. The sterilizing module further includes a housing having an ultraviolet outlet through which the sterilizing ultraviolet rays pass; a light source module for emitting the sterilizing ultraviolet rays; and a power storage member for supplying power to the light source module.

The present invention relates to a hydrogen water and sterile water-generating device that generates hydrogen water and sterile water by electrolysis. The hydrogen water and sterile water-generating device includes an electrolysis part that has at least two electrodes and electrolyzes water, a water introducing channel that introduces water into the electrolysis part, and a switch mechanism that switches the polarity of the electrodes between positive and negative, and hydrogen water and sterile water are generated in the same path by the switch mechanism switching the polarity of the electrodes between positive and negative during electrolysis.

An apparatus that can be connected to a conventional sprayer bottle that permits the sprayer bottle to generate ozonated and ionized water to be used as a cleaning fluid. The apparatus includes an ozonator element submerged in the bottle water via a first electrical conductor and an ionizer lead submerged in the water via a second electrical conductor which is connected to an ionizer that is not submerged. Respective apertures are formed in the sidewall of the bottle, each having respective electrical connectors to permit the respective electrical connections to different power sources. The dip tube of the spray head is then passed through the top opening and into the water in the bottle and the spray head is secured onto the bottle. Electrical energy is provided through the respective conductors to ozonate and ionize the water in the bottle for use a cleaning agent. Humidifier or vaporizer versions of this invention provide an ozonated and ionized water mist or vapor.

A reusable, multi-functional reusable bottle for reducing the amount of plastic waste generated by single-use utensils and single-use water bottles. The multi-functional reusable bottle efficiently and conveniently packages durable, reusable utensils for repeated use, eliminating the need for single-use utensils or bottled water. The multi-functional reusable bottle may be equipped with a magnetic removeable plate, at least one collapsible utensil, a removable cup, one or more straws and/or sip tips, a carbon filter liquid purifier, and any combinations thereof. In addition, the multi-functional reusable bottle may preferably be vacuum sealed, include a side strap for easy carrying, and be made of a durable metal that is washable and reusable over prolonged periods of time.

The present disclosure provides a means to remove oxidative compounds such as free halogen and chloramines from a liquid, while also providing components with antimicrobial properties in order to combat biofouling and the shedding of pathogens into liquids. In particular, methods of removing an oxidative compound from a liquid in which the liquid is contacted with one or more polymeric beads. As described herein, the oxidative compound binds to the polymeric bead and is removed from the liquid.

An apparatus that can be connected to a conventional sprayer bottle that permits the sprayer bottle to generate ozonated water to be used as a cleaning fluid. The apparatus includes an ozonator element coupled at one end of an electrical cable and an electrical connector coupled at the other end of the electrical cable. An aperture is formed in the sidewall of the bottle and the ozonator element, electrical cable and connector are passed through a top opening in the bottle portion. The electrical connector is then releasably secured within the aperture with the ozonator element being submerged in the water contained within the bottle. The dip tube of the spray head is then passed through the top opening and into the water in the bottle and the spray head is secured onto the bottle. Electrical energy is provided through the connector to the ozonator element to ozonate the water in the bottle for predetermined period of time after which the sprayer bottle contains ozonated water for cleaning. After another predetermined period of time, the ozonator element is energized again to ensure ozonated water is always available. A related apparatus can be connected between a feedpipe and a water reservoir for making the reservoir an ozonating water source.

A cartridge for use in a water purification apparatus and a water purification method for maintaining a water quality supply are provided. The cartridge comprises an elongated tubular body having first and second ends comprising a fluid inlet and a fluid outlet, and an internal chamber extending between the first and second end. The first end includes an end cap having a first opening in fluid communication with the body. A disinfectant material is disposed in the internal chamber of the body. Filters are disposed in the elongated tubular body adjacent to the first opening and adjacent the second end of the elongated tubular body and are in fluid communication with the internal chamber and the fluid outlet. The second end of the elongated tubular body comprising an exterior surface having a tapered portion and a linear portion adjacent to the tapered portion.

A water container for purifying water. The water container includes an opening configured to receive water, a container body arranged to enclose the water and a water purifying unit configured to purify the water. The water purifying unit includes an at least partially transparent plate, which includes a coating of metal-oxide nanoparticles on a first side facing the container body, wherein the first side is configured to be in contact with the water, and an ultraviolet light module configured to radiate towards a second side of the at least partially transparent plate such that light from the ultraviolet light module at least partially passes through the at least partially transparent plate. Also, a method for purifying water within a water container.

A non-biological, visible light photoreactor is provided, the photoreactor comprising: a fiberglass sheet, which includes fibers and interstitial spaces between the fibers; and a low iron oxide content, iron-doped titanium dioxide film on the fibers, the film containing about 0.5 atomic percent iron and an iron oxide content of less than about 0.075 atomic percent iron. The photoreactor may be configured as a tube with a light emitting diode housed therein, a cap at one end of the tube that has inlets to accept pressurized air and a plate at the other end of the tube, such that the air is forced through the photoreactor.
