Abstract:
A method of cleaning fouling materials from a radiation module, the method comprising the steps of: (i) immersing at least a portion of the radiation module in a fluid; and (ii) subjecting the radiation module to vibration at a frequency sufficient to substantially inhibit fouling materials adhering to the at least one radiation source. A radiation module for use in a fluid treatment system comprising: a support member for mounting the module in the fluid treatment system; at least one radiation assembly extending from the support member; and a vibration generator associated with the at least one radiation assembly. The radiation module is self-cleaning and can take the form of a radiation source module or a radiation sensor module. Incorporation of the radiation source module in a fluid treatment system is also described.
Abstract:
An immersible and portable module for irradiating waste fluids and capable of in situ self cleaning including a first header capable of receiving and maintaining in position a multiplicity of ultraviolet light producing lamps.The module includes a second header capable of receiving and maintaining in position said multiplicity of lamps and having an opening to receive cleaning fluids wherein the multiplicity of lamps are connected to the headers. The second header has a multiplicity of cleaning fluid exit holes proximate the lamps to permit the cleaning fluids to flow into the opening and outwardly from the holes and into contact with the lamps.
Abstract:
A water purification system having a pre-filter, a series of germicidal radiation chamber filter units alternating with a series of mechanical filter units and having a flow measuring device affixed to the output part of a final mechanical filtering unit. The rate of flow through the series of alternating germicidal and mechanical filtering units being measured by the flow measuring device and in turn controlled by an electrically operated valve so as to keep the rate of flow, of water being purified, through the series of alternating germicidal and mechanical filters at some predetermined and optimal setting with respect to the efficaciousness of the germicidal filters.
Abstract:
A circular cleaning device which scours the external surface of an ultraviolet radiation tube, which acts as a radiation source for bacteria kill in ultraviolet radiation fluid sterilizers, removes deposits, which precipitate out of the sterilizable fluid, from the external surface of the ultraviolet radiation tube, or its surrounding shield, and thereby sustains the emanation of high intensity radiation flux from the tube into the fluid which is to be sterilized.
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:
An embodiment provides a method for cleaning a surface, including: encapsulating a cleaning composition in a polymer material to form a compound, wherein the polymer material surrounds the cleaning composition; placing the compound in a location adjacent to the surface, wherein the location adjacent to the surface is a volume separated from an outer volume; dissolving the polymer material at a pH above a target value above the polymer material pH dissolution point, wherein the dissolving releases the cleaning composition; and cleaning the surface using the released cleaning composition. Other aspects are described and claimed.
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:
Disclosed herein is an apparatus having a double wiper structure for sterilizing ballast water. Each wiper for use in removing foreign substances from an ultraviolet lamp has a double structure including a main wiper part and auxiliary wiper parts. The auxiliary wiper parts are disposed on opposite sides of the main wiper part so that when the wiper body is moved forward or backward, the corresponding auxiliary wiper part primarily removes foreign substances before the main wiper part wipes the ultraviolet lamp unit. Each auxiliary wiper part includes an inclined protrusion and a pointed part so that friction between the surface of the ultraviolet lamp and the auxiliary wiper part can be minimized. The main wiper part includes a first blade and a second blade that are respectively disposed on opposite sides of a depression formed in an inner circumferential surface of the main wiper part.
