Non-plumbed appliances and filters are provided. A filter includes a body which includes a sidewall extending along a longitudinal axis between a first end wall and a second end wall, the body defining a body interior. The filter further includes an inlet defined in the body, and a nozzle protruding from the second end wall along the longitudinal axis and defining an outlet, the nozzle offset along an outer surface of the second end wall from a centroid of the outer surface. The filter further includes a tab configured on the body, and a filter medium disposed within the body interior, the filter medium operable to remove contaminants from water flowing through the filter medium.

A water treatment dispensing apparatus has a container for holding water from a water supply and a water disinfectant cartridge located within the container. A housing attached to the container and connected to the cartridge directs water from the cartridge to a remote location, such as a dental instrument. An air pressure device supplies water under pressure to the container to force water to flow through the cartridge and to the remote location.

Removable and replaceable outlets for point-of-use showers or faucets, filter devices, and methods and systems including the outlets and/or filter devices, are disclosed.

A water treatment device (100) can include a chamber (104) having an inlet (108) to receive water contaminated with pathogens and an outlet (110) to dispense treated water. The water treatment device (100) can also include a catalytic element (130) disposed in the chamber (104) to deactivate the pathogens in the water via at least one of electrocatalytic activity and photocatalytic activity. The chamber (104) and/or the catalytic element (130) can be configured to mix the water as the water flows from the inlet (108) to the outlet (110) thereby exposing the pathogens in the water to the catalytic element (130).

A base product fluid is produced by adding anhydrous liquid ammonia and a first portion of sulfuric acid to water in a process line to form a mixed fluid. The mixed fluid may be cooled and a second portion of sulfuric acid may be added to the mixed fluid to form the base product fluid. The base product fluid may include a molecular compound that is a chelating compound. The molecular compound may have the formula: ((NH.sub.4).sub.2SO.sub.4).sub.a.(H.sub.2SO.sub.4).sub.b.(H.sub.2O).sub.c.(NH.sub.4HSO.sub.4).sub.x. In the formula, a may be between 1 and 5, b may be between 1 and 5, c may be between 0 and 5, and x may be between 1 and 20.

A self-cleaning fountain includes: a structure having two ends, defining a first flow way for a first fluid to flow along, wherein the structure defines holes for allowing a second fluid to flow through the holes; a pump system configured to pump the first fluid to a first end of the structure; a distributer located at the first end of the structure and configured to spray the first fluid received from the pump system onto the structure; a catch basin located at a second end of the structure for collecting the first fluid that has moved along the flow way to the catch basin; a photocatalytic coating on the structure; and a light source configured to direct light on the photocatalytic coating.

A negative hydrogen ion intelligent filtration system includes a housing; a filtering mechanism disposed in the housing and comprising a first filter, a second filter connected to the first filter, a third filter connected to second filter, a fourth filter connected to the third filter, a fifth filter connected to the fourth filter, a sixth filter connected to the fifth filter, a seventh filter connected to the sixth filter, an eighth filter connected to the seventh filter, a ninth filter connected to the eighth filter, a tenth filter connected to the ninth filter, a eleventh filter connected to the tenth filter and a twelfth filter connected to the eleventh filter; an inflow port connected to the first filter and extending out of the housing; an outflow port connected to the twelfth filter and extending out of the housing; and a flow rate control mechanism disposed in the housing, located between the first filter and the inflow port and connecting the first filter and the inflow port.

Bi-metal nanoadsorbents and methods for their preparation and use are provided. Methods of using bi-metal nanoadsorbents to remove contaminants from samples, such as water, are also provided.

This invention falls within the scope of sanitary and hygiene, and of antiseptic formulations in particular, including disinfectants intended for disinfection of water in swimming-pools and other artificial reservoirs, for sanitary and hygienic treatment of rooms, household equipment, furniture, household appliances and industrial equipment, as well as for disinfection of rinse and waste water. An antiseptic formulation contains nanosized particles containing both silver and silver chloride. An antiseptic formulation can additionally contain at least one amphoteric surface-active substance. In order to perform disinfection of water, nanosized particles containing silver and silver chloride are added into water at least once.

A method and apparatus for treating a body of water to kill microorganisms by enhancing the concentration metal ions therein. The apparatus comprising a dispenser with a first housing having a water accessible compartment containing a source of 5,5-dimethylhydantoin for releasing the 5,5-dimethylhydantoin when contacted by the body of water and a second housing having a water accessible compartment containing an insoluble metal ion donor for releasing metal ions when contacted by the body of water containing the 5,5-dimethylhydantoin
