Abstract: A solution for treating a fluid, such as water, is provided. An ultraviolet transparency of a fluid can be determined before or as the fluid enters a disinfection chamber. In the disinfection chamber, the fluid can be irradiated by ultraviolet radiation to harm microorganisms that may be present in the fluid. One or more attributes of the disinfection chamber, fluid flow, and/or ultraviolet radiation can be adjusted based on the transparency to provide more efficient irradiation and/or higher disinfection rates. In addition, various attributes of the disinfection chamber, such as the position of the inlet(s) and outlet(s), the shape of the disinfection chamber, and other attributes of the disinfection chamber can be utilized to create a turbulent flow of the fluid within the disinfection chamber to promote mixing and improve uniform ultraviolet exposure.

Abstract: A variety of applications for UV LEDs that are integrated into a system are described, where the UV light is used for disinfection of air or surfaces, or used to detect the scattering light by particles, or used for skin treatment. In one embodiment, a ceiling luminaire includes a sensor for detecting the presence of people in the room. The luminaire contains a first set of LEDs for generating white light, for illumination, and a second set of LEDs for generating UV light for disinfecting the room. When the sensor detects that no people are in the room, the system automatically controls the UV LEDs to turn on to disinfect the room. The white light LEDs may be independently controlled with a dimmer.

Abstract: A sterilization device includes a treatment chamber provided with multiple inlet ports and an outlet port, and multiple light sources that irradiate a fluid flowing within the treatment chamber with ultraviolet light. Each of the multiple light sources is disposed so as to emit ultraviolet-light toward a fluid flowing closer to the corresponding inlet port than to the outlet port. The treatment chamber may be of a shape extending in the longitudinal direction from a first end surface toward a second end surface. The multiple light sources may include the first light source disposed on the first end surface and the second light source disposed on the second end surface.

Abstract: The invention relates to a liquid purification assembly using ultraviolet light irradiation against reproduction of pathogenic microorganisms, comprising an irradiation chamber (200) having an internal volume and comprising an inlet (204) and an outlet (205), the irradiation chamber (200) being provided with ultraviolet light emitting means (208) configured to irradiate liquid in the irradiation chamber (200) with ultraviolet light. The irradiation chamber (200) comprises a mechanism configured to cause a change in the internal volume of the irradiation chamber (200), said change in internal volume drawing liquid into the irradiation chamber (200) when the volume of the irradiation chamber (200) increases, and forcing liquid out of the irradiation chamber (200) when the volume of the irradiation chamber (200) decreases. The invention also relates to a beverage dispenser and to a method for purifying a liquid.

Abstract: A purifying method for photochemical elimination of xenobiotics present in water. The purifying device is used which has a photochemical reactor unit having at least one inlet for contaminated water and one outlet for purified water, it provides a flow path for continuously flowing water from said inlet to said outlet, and is equipped with a radiation source module providing ultraviolet radiation in a wavelength range ranging from 100 to 280 nm. The method includes performing ultrafiltration, thereby removing suspended and solvated macromolecular matter from the water; conducting the permeate via the at least one inlet into the photochemical reactor unit; subjecting the water flowing from said inlet to said outlet to ultraviolet radiation at wavelengths ranging from 100 to 280 nm, thereby generating hydroxyl radicals initiating degradation of said xenobiotics; and supplying air or dioxygen into the water, thereby enhancing the initiated oxidative degradation of said xenobiotics.

Abstract: Methods are provided for disinfecting water mains using ultraviolet (UV) light. One or more UV light sources are provided and secured to a movable device that moves axially in a pipe. The frequency and intensity of the UV light is determined based on characteristics of the pipe, such as its material and size. The rate at which the movable device moves through the pipe is also determined so that the interior surface of the pipe is properly disinfected. The movable device is remotely caused to move through the pipe.
