An ultraviolet (UV) irradiation apparatus according to an embodiment includes a treatment tank, a UV irradiation member, a UV sensor, and an air outlet unit. The treatment tank includes a water supply opening to supply therethrough treated water to be further treated and a water drainage opening to drain therethrough the treated water. The UV irradiation member is provided inside the treatment tank and irradiates treated water with UV light when the treated water passes through inside of the treatment tank. The UV sensor is provided inside the treatment tank and measures a dose of UV irradiation from the UV irradiation member. The air outlet unit is connected to an air outlet hole provided at a position higher than a horizontal plane that passes through the UV sensor, and is provided to release, to the outside of the treatment tank, through the air outlet hole, air that accumulates inside the treatment tank when the treated water passes through the inside of the treatment tank.

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:
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 there between. 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.
