An assembly comprises a wet compartment (100) having at least one inlet opening for allowing water to enter the wet compartment (100), a functional unit (2) located in the wet compartment (100), a dry area (200) which cannot be reached by water and which is outside of the wet compartment (100), a barrier (110) situated between the dry area (200) and the wet compartment (100), and at least one energy source (20) which is arranged and configured to emit energy for preventing biofouling of at least an exterior surface (17) of the functional unit (2), wherein the energy source (20) is arranged in the dry area (200), a path (112) being present between the dry area (200) and the wet compartment (100) for allowing energy emitted by the energy source (20) during operation thereof to reach the wet compartment (100), through the barrier (110).

A ventilation ring for a UV water sanitizer unit that allows for adequate ventilation of heat generated by electronic components while sequestering those electronic components from water. The ring can also be made of a transparent or translucent material to allow a user to detect whether a UV lamp within the housing is operating. An improved nut for affixing a quartz tube within such a unit and improved design for draining the unit are also disclosed.

The present disclosure relates to devices and methods for the disinfection of a flowing water sample using ultraviolet light.

A laser ablation and filtration process and apparatus wherein liquid containing hydrocarbons or other contaminants is purified. The liquid is exposed to laser energy at one or more selected wavelengths wherein the laser energy travels through the liquid and reaches the hydrocarbons or other contaminants and vaporizes, denatures, breaks down, neutralizes, renders inert and/or separates the hydrocarbons or contaminants from the liquid. A laser source is positioned in or on a vessel based on pre-set parameters to maximize exposure of the liquid to the laser energy, including sizing parameters, angle and inclination of the laser, retention time for the laser process to be applied and geometry of the containment for proper inclination. One or more collection chambers, which may include perforated membranes may be included to collect gases, separated hydrocarbons or contaminants and other by-products of the process. The vessel utilized may be submergible in water to pull or flow contaminated water therethough. The vessel may also be utilized outside a body of water wherein contaminated water from a source is introduced within the vessel.

A fluid sterilization device according to an embodiment includes: a cylindrical part; a light source, emitting ultraviolet rays to a fluid flowing through an inside of the cylindrical part via a window; a water turbine, provided inside the cylindrical part; and a removal part, provided at the water turbine. An end part of the removal part is brought into contact with a surface of the window on a side opposite to a side of the light source.

A fluid disinfecting system includes a straight fluid directing conduit and a light source disposed on a side of the fluid directing conduit. The light source is operative to emit ultraviolet light into the fluid directing conduit, such that one or more cross sections of said fluid directing conduit are saturated with ultraviolet light. Any fluid passing through the fluid directing conduit is necessarily exposed to the ultraviolet light.

A disinfecting system includes a housing. An ultraviolet light (UV) source is secured to the housing and configured to emit UV light for disinfection of a target. A processor is secured to the housing in communication with the UV light source. The processor is configured to activate the UV light source for a selected amount of time suitable for disinfection of the target.

An object is to provide a cap unit capable of enhancing the sterilizing ability with respect to an object to be sterilized while maintaining water stopping properties in a housing, and capable of irradiating a desired range with ultraviolet light, as well as a storage tank and a flowing water sterilization device.

The cap unit includes: a light source unit including a light emitting element and a substrate on which the light emitting element is mounted; a housing that has an accommodation space for the light source unit and an opening at a predetermined position on a side that faces an object to be sterilized, the housing being configured to accommodate the light source unit so that the opening and the light emitting element face each other; an ultraviolet light transmitting window portion configured to close the opening; and a gasket positioned between the light source unit and the ultraviolet light transmitting window portion so as to prevent the object to be sterilized from entering a side with the light source unit in the accommodation space, wherein the gasket includes a reflector wall portion that has a light reflection property and that is recessed toward the light source unit so as to surround a side region of the light emitting element.

The invention relates to a process for the disinfection of liquids or gases with the process steps: Creating a radiation barrier in a disinfection chamber, introducing a gas and/or a liquid flow into the disinfection chamber, guiding the gas and/or liquid flow through a plurality of volume ranges of the disinfection chamber and discharging the gas and/or liquid flow from the disinfection chamber, wherein the volume ranges in the disinfection chamber are formed by the radiation barrier, a chamber wall and a flow guiding surface of a flow guiding element and the volume ranges are completely separated from each other by the chamber wall, the radiation barrier and the flow guiding surface, as well as a device for carrying out the method.
