Abstract:
The present invention provides a radiation source module for use in a fluid treatment system. In one embodiment, the module comprises: a substantially elongate first support member having a longitudinal first axis; and a first pair of radiation source assemblies extending from the first support member, each radiation source assembly comprising a radiation source; wherein the first pair of radiation source assemblies is oriented such that a second axis extending through a center point of each radiation source assembly is disposed at an angle with respect to the first axis. In another embodiment, the module comprises a substantially elongate first support member having a longitudinal first axis; and a first column of radiation source assemblies extending from the first support member, and a second column of radiation source assemblies extending from the first support member, each radiation source assembly comprising a radiation source;the first column of radiation source assemblies and the second column of radiation source assemblies disposed adjacent one another.
Abstract:
A radiation source module comprising a support member, a radiation source assembly connected to the support member, the radiation source assembly comprising at least one elongate radiation source having a source longitudinal axis and a module-to-surface seal disposed on a first elongate surface of the module, the first elongate surface comprising a first longitudinal axis transverse to the source longitudinal axis, the seal operable to provide a substantially fluid tight seal between the first surface and a second surface which is adjacent to the first surface. A fluid treatment system employ the radiation source module is also described.
Abstract:
A cleaning formulation comprising a cleaning agent, a particulate clay material and an aqueous carrier. The formulation has a pH less than about 4.0 and is characterized by at least a 90% reduction in viscosity at 25null C. at a shear rate of up to about 0.10 snull1. The cleaning formulation is thixotropic and has a highly desirable combination of acid stability, temperature stability, electrolyte stability and ultraviolet radiation stability.
Abstract:
A radiation sensor having structure to remove fouling materials includes a sensor housing, and radiation transmissive structure within the housing and including a portion to be exposed to a radiation source. A radiation sensor is provided for receiving radiation from the transmissive structure. Structure is also provided for removing materials fouling the portion of the radiation transmissive structure to be exposed to the radiation source.
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:
For ultraviolet purification or sterilization of fluids, particularly waste water, lamp sections, each composed of opposed pairs of fluid impermeable light unit receiving sockets and lamp units therebetween are provided. Each lamp section consists of an inner, elongate, cylindrical ultraviolet ray emitting lamp and an outer, coaxial and substantially co-extensive cylindrical sleeve, arranged in parallel rows. Due to its immersion capability, the array of rows of lamps can be fluid immersed in either an open or closed system. Moreover, lamp withdrawal, fluid impermeable closure means is provided on at least one of each pair of sockets to facilitate lamp withdrawal in the event of burnout. Each row of lamps can also be modularized to facilitate easy removal of a malfunctioning row of lamps without having to shut down or remove the entire device from its fluid environment.
Abstract:
A radiation source assembly comprises a source base, a UV transparent sleeve, and a UV lamp. The source base comprises a sealed electrical connection interface and an opposing sealed sleeve interface. The sealed electrical connection interface comprises a electrical contacts and the sealed sleeve interface comprise a radial sealing element, an outer collar, and a compression ring. The UV transparent sleeve is engaged with the sleeve interface such that the radial sealing element of the sealed sleeve interface is disposed between the UV transparent sleeve and the outer collar of the source base, and the compression ring is positioned over the UV transparent sleeve and engaged with the source base to compress the radial sealing element onto the UV transparent sleeve and the outer collar. The UV lamp is disposed within the UV transparent sleeve and electrically coupled to the electrical contacts of the electrical connection interface.
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.
