The power generation unit is provided in the housing and is coupled to the spoiler unit. The sterilization unit is provided in the housing and is electrically connected to the power generation unit, and includes a sterilization light source. The purification unit is provided in the housing and corresponds to the output portion and the sterilization unit, and includes a plurality of purification particles. Thus, the water filter is enabled to be coupled to a faucet using the first thread portion, allowing tap water to flow toward the direction from the input portion to the output portion.

An assembly comprising at least two elements in a movable arrangement relative to each other for performing a first function of the assembly is furthermore equipped with an anti-biofouling system for subjecting at least an area of the assembly that is to be at least partially exposed to water during at least a part of its lifetime to an anti-biofouling action as an additional function of the assembly, different from the first function of the assembly. The anti-biofouling system comprises one or more light sources for emitting anti-biofouling light, and the anti-biofouling system is adapted to realize coverage of the area with the anti-biofouling light on the basis of the movable arrangement of the at least two elements relative to each other for performing the first function of the assembly.

A UV reactor for disinfecting water. The UV reactor may include a cooling chamber in which heat from a UV source may be transferred to the water flowing through the UV reactor. The UV reactor may include driver circuitry operable to determine status information, such as health, of the UV source. The UV reactor may include a gas discharge path operable to substantially prevent accumulation of gas within a water treatment chamber.

A device is provided for disinfecting water of a swimming pool, which includes an inlet for water from the swimming pool and an outlet for the water, an ozonation device, and a mixing section for ozone-containing water, wherein the ozonation device includes at least one UV light source for generating ozone, and an admixing unit for admixing the ozone to the water of the inlet, and the mixing section comprises a housing connected to the inlet, wherein the UV light source is arranged within the housing to emit UV light into the housing interior. The housing has deflecting surfaces for water protruding into the housing interior, which ensure a meandering flow within the housing. The device enables improved disinfection and can be designed to be more space-saving and visually appealing than conventional devices.

A UV reactor comprises a main chamber extending in a generally longitudinal direction. The main chamber may comprise a UV-LED and a reflective wall located at opposing longitudinal ends of the main chamber. Fluid enters main chamber through a fluid inlet and exits main chamber through a fluid outlet. The fluid inlet may be located at the reflective wall end of the main chamber. The fluid outlet may be located at the UV-LED end of the main chamber.

Embodiments relate to systems, devices, and methods for sanitizing stored contents. System includes main and secondary assemblies. Main assembly includes main opening and main storage section. Secondary assembly includes securing portion, radiation assembly, and control assembly. Securing portion transitions between secured and unsecured states. Secured state is when main and secondary assemblies are secured together. Radiation assembly is configured to emit radiation, and is formed symmetrically relative to a central axis. Control assembly includes first and second safety assemblies and control processor. First safety assembly is configured to determine whether the storage system is in the secured or unsecured state. Second safety assembly is configured to determine whether the secondary assembly is in a safe or unsafe orientation state. Control processor is configured to control the radiation assembly to emit radiation when the storage system is in the secured state and the secondary assembly is in the safe orientation state.

The invention provides an object (10) that during use is at least partly submerged in water, the object (10) further comprising an anti-bio fouling system (200) comprising an UV emitting element (210), wherein the UV emitting element (210) comprises one or more light sources (220) and is configured to irradiate with UV radiation (221) during an irradiation stage one or more of (i) a part (111) of an external surface (11) of said object (10) and (ii) water adjacent to said part (111) of said external surface (11), wherein the object (10) is selected from the group consisting of a vessel (1) and an infrastructural object (15), wherein the object (10) further comprises a water switch (400), wherein the anti-bio fouling system (200) is configured to provide said UV radiation (221) to said part (111) in dependence of the water switch (400) being in physical contact with the water.

In a sterilization apparatus and a sterilization container using the same according to an embodiment of the present invention, provided is a sterilization apparatus including: an accommodation unit accommodating an object therein, and having an entrance through which the object enters and exits formed on one side and a connector formed on the other side; a coupling unit supporting the accommodation unit provided in the connector; and a sterilization unit disposed adjacent to the accommodation unit by the coupling unit, and irradiating light to the inside of the accommodation unit through the connector to sterilize the object.

Fluid purification systems employing a monolithic composite photocatalyst to remove volatile organic compounds (VOCs) and/or pathogenic organisms are disclosed. Pairing of systems tuned to abate each of these materials are discussed in different configurations such as series and parallel, as well as combining systems to target both materials simultaneously. System configurations that allow a portion of the fluid stream to be purified are also disclosed as are configurations that allow regeneration of the photocatalyst. These features may be augmented by sensors that allow closed loop control of bypass and regeneration cycles in the systems.
