Abstract:
PROBLEM TO BE SOLVED: To dissolve and peel inorganic scale attached to a storage tank storing water to be treated, pipes and jackets of ultraviolet lamps without using any chemical. SOLUTION: This photocatalytic water treatment apparatus decomposes organic and inorganic substances in water 100 to be treated using the storage tank 11, and is provided with an apparatus body part 2 disposed outside the storage tank 11; a circulating line consisting of a water taking-in pipe 8 connected to a water taking-in side of the body 2 and a discharge pipe 9 connected to a discharge side of the body 2; a pump 4 circulating the water 100 to be treated; a filter 5 provided in the body 2; a photocatalytic treatment means provided on a downstream side of the filter 5 using photocatalyst carriers 7 and the ultraviolet lamps 6; and an electrode part 3 provided in the tank 11. The water 100 to be treated is electrolyzed by energizing the electrode part 3. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
A scraper for removing deposits from the exterior of a tubular member includes elements defining an outer jacket which has an inwardly open circumferential recess and two aligned axial openings, and a scraper element in the form of an elongate resilient wire bent to define a series of integral, concatenated, resilient segments, each pair of adjacent segments being connected through a bend or geniculation. All geniculations are received within the recess, and each segment of wire extends generally along a chord of the aligned axial openings. The positions of the chords are distributed around the circumference of the axial openings such that, in order for the tubular member to be accommodated through the aligned openings, the various segments must be deformed outwardly, whereby the resilience of the thus deformed segment urges it inwardly against the tubular member, and causes it to clean the tubular member as the scraper moves axially.
Abstract:
A disinfection apparatus and method is provided for disinfecting a fluid. The apparatus elements define three internal container volumes. Fluid is introduced into an entry volume where its flow is conditioned to reduce splash and slow the fluid flow. The fluid is then channeled into a disinfection volume where a disinfection unit delivers a disinfection agent to the fluid. Finally, the fluid exits the apparatus through an exit volume. In one aspect, a sink-trap is disclosed in which wastewater liquid contacts a pair of diverters. The diverters have conditioned contact surfaces that slows and spreads the liquid flow and reduces liquid splash. The wastewater then passes through a UV chamber in which it is disinfected. The liquid then exits the sink-trap. Advanced self-cleaning apparatus are additionally disclosed to clean and disinfect the sink-trap and trapped wastewater. The entire apparatus operates under computer control.
Abstract:
A fluid sterilization device includes: a flow passage tube in which a processing passage where a passing fluid is sterilized is formed; an inflow passage or an outflow passage formed in the flow passage tube; a light source that irradiates the processing passage with ultraviolet light; and a rotating body provided in the processing passage. The rotating body is rotated around a longitudinal direction of the processing passage in response to a flow of the fluid passing through the processing passage and is configured to come into contact with an inner wall of the flow passage tube during rotation.
Abstract:
A ballast water treatment system includes at least one UV-light reactor with at least one UV-lamp, an inlet line for ballast water to be treated connected to the reactor and an outlet line connected to the reactor. The system includes a cleaning system for periodic cleaning of the reactor, including a water inlet line connected to the reactor for supplying water, a container with concentrated CIP-liquid connected to the reactor, a CIP-liquid inlet line connecting the container to the reactor, a dosage pump arranged in the CIP-liquid inlet line for supplying a predetermined amount of concentrated CIP-liquid to the reactor to mix with the water, a circuit comprising the reactor and a pump arranged in the circuit for circulation of water mixed with the concentrated CIP-liquid.
Abstract:
There is disclosed a cleaning apparatus for a radiation source assembly in a fluid treatment system. The clean apparatus comprises a cleaning sleeve moveable to remove fouling materials from an exterior portion of the radiation source assembly, the cleaning sleeve comprising at least one chamber for receiving a cleaning fluid and a cleaning sleeve inlet in fluid communication with the at least one chamber and a first conduit element for conveying the cleaning fluid to the cleaning sleeve inlet, the first conduit element being configured such that a distal portion of the first conduit element is in fluid communication with the cleaning sleeve inlet and a proximal portion of the first conduit element is disposed outside of fluid being treated in the fluid treatment system.
Abstract:
There is described a radiation source module for use in a fluid treatment system. The radiation source module comprises: a housing having an inlet, an outlet and a fluid treatment zone disposed between. The fluid treatment zone comprises a first wall surface and a second wall surface interconnected by a floor surface. The first wall surface, the second wall surface and the floor surface are configured to receive a flow of fluid through the fluid treatment zone. The radiation source module further comprises at least one radiation source assembly secured with respect to the first wall surface and the second wall surface and a module motive coupling element connected to the housing and configured to be coupled to a module motive element to permit the radiation source module to be installed in and extracted from the fluid treatment system. A fluid treatment system comprising the radiation source module is also described.
Abstract:
The present invention is generally directed to a split drive assembly for an ultraviolet (UV) disinfection module comprising one or more UV lamps extending between one or more headers and a cleaning plate having openings therein arranged to substantially coincide with the UV lamps to permit movement of the cleaning plate along the UV lamps, the split drive assembly operatively connected to a moving device, the split drive assembly including a split drive nut having an internal bore for attachment to the moving device, the drive nut comprising at least two portions attached together around the moving device. Other aspects of the invention may include a sleeve guide including an attachment plate to attach the sleeve guide to a surface of the cleaning plate; a sleeve extended from the attachment plate; and an alignment device in contact with a UV lamp, the alignment device attached to the sleeve.
