Abstract:
According to one embodiment, an apparatus for measuring hydroxyl radicals that measures hydroxyl radicals produced by irradiating a liquid to be treated flowing through a channel in which an ultraviolet lamp is arranged with ultraviolet rays, the apparatus includes a diverting unit, a reagent adding unit, and a measuring unit. The diverting unit has a diverting channel that diverts the liquid to be treated before being irradiated with the ultraviolet rays from the channel and part of which is arranged at a position enabling the liquid to be treated within the channel to be irradiated with the ultraviolet rays. The reagent adding unit adds a hydroxyl radical measuring reagent to the diverted liquid to be treated. The measuring unit irradiates the diverted liquid to be treated with the ultraviolet rays and measures the amount of hydroxyl radicals produced based on a change in the hydroxyl radical measuring reagent between before and after the irradiation with the ultraviolet rays.

Two electrodes and an ultraviolet lamp are mounted to the second housing and extend into the second housing. The electrodes are electrically connected to a power supply. A fine filtration module includes a third housing receiving a fine filter. A piping unit includes a plurality of pipes and a plurality of valves. The valves connect the first, second, and third housings to intercommunicate the first, second, and third housings with each other. The valves are mounted on the pipes to control communication between the pipes.
Abstract:
There is described a radiation source module for use in a fluid treatment system. The radiation source module comprises a plurality of elongate radiation source elements secured to a frame element, each elongate radiation source element having a longitudinal axis; a first motive element secured to a first side portion of the frame element; and a second motive element secured to a second side portion of the frame element. The first motive element and the second motive element are configured to reversibly translate the plurality of elongate radiation source elements in a direction substantially parallel to the longitudinal axis. A fluid treatment system comprising the radiation source module is also described.
Abstract:
Humidifying apparatus includes a body comprising a chamber into which water is supplied by a water tank. An air flow is generated over water stored in the chamber, and a humidifying system humidifies the air flow with water from the chamber. Water in the chamber is irradiated by an ultraviolet radiation emitting lamp. The lamp forms part of a cartridge removably locatable within the body so that the lamp is received within an ultraviolet radiation transparent tube of the chamber. The body includes a plurality of supports for supporting the cartridge therebetween. Each support has a curved track for guiding movement of the cartridge towards the tube, the tracks being shaped to orient the cartridge for insertion of the lamp into the tube as the cartridge moves along the tracks towards the tube.

Abstract:
A process has been developed to selectively dissociate 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. This process can be used for the remediation of water, particularly ballast water.
Abstract:
A system and method for powering an ultraviolet (UV) water purification system utilizing a dynamo. A dynamo, operably attached to the UV water purification system, generates power from a rotatable crank which is actuated by a user around an axis of the rotatable crank. When the crank is rotated, the dynamo produces an electrical current that activates and powers the UV lamp, which in turn, produces UV light to purify the water. To ensure that the water has been purified appropriately, a microcontroller, employed within the UV water purification system, tracks both the “on” time and the intensity of the UV lamp as the dynamo is cranked. Once the lamp has been “on” at a sufficient intensity and for an appropriate period of time to administer a required dose of UV light, the microcontroller disables the lamp and provides the user with notification that the process has completed.
Abstract:
The present invention relates to a device for supplying cold and hot water having a sterilization function by using UV light, and more specifically, to a device for supplying sterilized cold and hot water which includes a UV sterilization lamp and a see-through window for easily checking the contamination state of the inside of a water tank with the naked eye. The device for supplying sterilized cold and hot water according to one embodiment of the present invention is characterized in that the entire top surface or the entire side surface of the water tank is formed as a see-through window such that the internal state thereof can be checked from the outside.
