Internally activated energy distribution guides for use in clear to turbid liquids or air have been developed. An external energy source is transferred to a matrix or single fiber of a side emitting fiber or guide to internally activate a promoter or catalyst on the exterior of the fiber or guide to thereby dissociate target molecules passing by or along the fiber's or guide's surface by a Precise Energy Separation (PES) method. A number of different designs can be used, for example, in a mesh, louver system, or box. The method maximizes the interaction between the target molecules and the surface of the side emittinginternally activated distribution network. In a preferred embodiment, u-shaped fiber optics containing catalyst are positioned within tube through which the turbid liquid or air is passed, so that maximum cleavage of targeted bonds is obtained.

A water vending apparatus is disclosed. The water vending system includes a water vapor distillation apparatus and a dispensing device. The dispensing device is in fluid communication with the fluid vapor distillation apparatus and the product water from the fluid vapor distillation apparatus is dispensed by the dispensing device.

A water quality measurement device 1 includes a twin tube excimer lamp 2. The inflow pipe 3 is connected to one end of the inner tube 21 of the excimer lamp 2, and the outflow pipe 4 is connected to the other end of the inner tube 21 of the excimer lamp 2. The detector 5 that measures the conductivity of sample water is interposed in the outflow pipe 4. In the water quality measurement device 1, sample water sequentially flows through the inflow pipe 3, the inner tube 21 of the excimer lamp 2, and the outflow pipe 4. Hence, the channel in the water quality measurement device 1 can be simplified. Additionally, the sample water is oxidized by being irradiated with UV light in the inner tube 21 of the excimer lamp 2. Hence, it is possible to irradiate the sample water with UV light from the excimer lamp 2 efficiently.

A light emitting module including a light source configured to irradiate ultraviolet light, a board on which the light source is disposed, a tube accommodating the board and including a transparent region to transmit the ultraviolet light emitted from the light source, a first base coupled to one side of the tube, a second base coupled to the other side of the tube, a fixation groove disposed in the tube and connected to at least one of the first and second bases, in which the board is coupled to be inserted into the fixation groove, and the fixation groove is spaced apart from a center of the first base when viewed in a cross-section perpendicular to a length direction of the tube.

A vehicle system includes a tank for storing an aqueous solution; and a UV light decontamination module configured for decontaminating aqueous solution stored in the tank. The UV light decontamination module is arranged in a wall of the tank. The UV light decontamination module includes a light source compartment which is accessible from an external area outside of the tank; and a light transmission member configured to transmit UV light from the light source compartment to a liquid space in fluid communication with aqueous solution stored in the tank. The light source compartment includes a light source to emit UV light through the light transmission member to the liquid space.

The present disclosure is directed to smart, portable, reusable liquid containers, or container assemblies, with ultraviolet (UV) sterilization capability. An example container assembly includes a container defining a cavity to hold liquid. A cap coupled to the container prevents the liquid from spilling out of the cavity. A liquid level sensor and a processor track the amount of fluid within the container. When they detect liquid added to the container, they trigger one or more UV light sources for sterilizing the liquid. A cap sensor in or on the container assembly senses if the cap is on the container and prevents UV light source operation when the cap is off. The processor may communicate with a remote device, e.g., a smart phone or server, via an antenna. Indicators in or on the container assembly notify a user that UV sterilization is recommended, UV sterilization is in progress, etc.

A system has been developed to treat ballast water by selectively dissociating target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism.
