20090250624 | INSTALLATION AND METHOD FOR THE PURIFICATION OF AN AQUEOUS EFFLUENT BY MEANS OF OXIDATION AND MEMBRANE FILTRATION - A system and method is provided for utilizing ultraviolet light to disinfect water. The system includes a plurality of ultraviolet lights with each ultraviolet light including a sheath that is transparent to ultraviolet radiation. Mounted adjacent the ultraviolet lights is a drive that moves back and forth with respect to the ultraviolet lights. Operatively interconnected with the drive is a support structure that includes a plurality of bearing rings. Inserted and held within each bearing ring is a scraping ring that in turn surrounds a respective sheath of an ultraviolet light. Actuation of the drive results in the support structure moving back and forth with respect to the ultraviolet lights and results in the scraping ring scraping and cleaning the respective sheaths. | 10-08-2009 |

20120061585 | ULTRAVIOLET WATER TREATING APPARATUS - An ultraviolet water treating apparatus according to one embodiment has an ultraviolet irradiation unit, and water inlet and outlet pipes. The unit includes a hollow enclosure with first and second openings in its peripheral wall. Within the enclosure, one or more ultraviolet irradiation devices are provided, which irradiate ultraviolet light onto the water flowing through the enclosure. Also within the enclosure, a cleaning device is provided, which includes a cleaning tool to clean the surface of each protective sleeve, and a driving unit to move the cleaning tool along the protective sleeve. The inlet pipe is in fluid communication with the first opening and flows the water therethrough into the enclosure. The outlet pipe is in fluid communication with the second opening and flows the ultraviolet-irradiated water therethrough out of the enclosure. The inlet and outlet pipes have their central axes intersected with the central axis of the enclosure. | 03-15-2012 |
20130068964 | ULTRAVIOLET IRRADIATION DEVICE - An ultraviolet irradiation device includes a treatment vessel, an ultraviolet irradiation member, and a support member. The treatment vessel has a water inlet and a water outlet and through which water to be treated as a treatment target flows in a first direction from the water inlet toward the water outlet, the treatment vessel receiving the water to be treated through the water inlet and discharging the water to be treated through the water outlet. The ultraviolet irradiation member is provided inside the treatment vessel along a second direction crossing the first direction and which irradiates the water to be treated flowing through the treatment vessel with an ultraviolet ray. The support member is provided inside the treatment vessel along the second direction with both end portions of the support member being firmly fixed to wall surfaces of the treatment vessel. | 03-21-2013 |
20130277571 | FLUID TREATMENT SYSTEM - A fluid treatment system having an inlet, an outlet, and a fluid treatment zone therebetween. The zone has an array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis disposed at an oblique angle with respect to a direction of fluid flow. Each row has a plurality of radiation source assemblies in spaced relation in a direction transverse to the direction of fluid flow, to define a gap through which fluid may flow between an adjacent pair of assemblies. Preferably, all rows in the array are staggered with respect to one another in a direction orthogonal to the direction of fluid flow, such that the gap between an adjacent pair of radiation source assemblies in an upstream row of assemblies is partially or completely obstructed in the direction of fluid flow by a serially disposed radiation source assembly in at least one downstream row. | 10-24-2013 |
20140374618 | ULTRAVIOLET WATER TREATMENT DEVICE - An ultraviolet water treatment device of an embodiment includes an ultraviolet irradiation tank.

The ultraviolet irradiation pipes include a plurality of lines of ultraviolet lamps and a plurality of lines of ultraviolet lamp protective pipes individually protecting the ultraviolet lamps. The cleaning device cleans a surface of each ultraviolet lamp protective pipe. Each ultraviolet irradiation module includes two or three ultraviolet irradiation pipes. | 12-25-2014 |
20140374619 | METHODS AND APPARATUS FOR CLEANING OBJECTS IN A CHAMBER OF AN OPTICAL INSTRUMENT BY GENERATING REACTIVE IONS USING PHOTON RADIATION - An optical instrument, including a chamber, an object exposed to an interior of the chamber, a source of low-pressure gas, the gas comprising at least one of low-pressure molecular hydrogen gas, low-pressure molecular oxygen and a low-pressure noble gas, the source of low pressure gas being fluidly coupled to the chamber, a low voltage source electrically coupled between the object and a remaining portion of the instrument that is exposed to the interior of the chamber so as to maintain the object at a low voltage relative to the remaining portion, and an EUV/VUV light source adapted to direct EUV/VUV light through the low pressure gas in the chamber onto the object. In such a system, when the EUV/VUV light source is activated ions of the low-pressure gas are formed and directed to the object. The ions may be ions of Hydrogen, Oxygen or a noble gas. | 12-25-2014 |
20150329380 | CLEANING APPARATUS - There is disclosed a cleaning apparatus for a radiation source assembly in a fluid treatment system. The cleaning system comprises: a cleaning carriage comprising at least one cleaning element for contact with at least a portion of the exterior of the radiation source assembly; a rodless cylinder comprising an elongate housing having a longitudinal axis; a slidable element disposed on an exterior surface of the elongate housing, the slidable element being: (i) coupled to the cleaning carriage, and (ii) magnetically coupled to a driving element disposed within the elongate housing, the driving element comprising a friction modifying element in contact with an interior surface of the elongate housing to define a first frictional resistance in a rotational direction about the longitudinal axis and a second frictional resistance in an axial direction along the longitudinal axis, the friction modifying element configured such that the first frictional resistance is greater than the second friction resistance; and an elongate motive element coupled to the driving element. | 11-19-2015 |
