Abstract: In order to disinfect and to detoxify a fluid, a photoreactor contains at least two light sources. One light source activates the catalytic function of a semiconductor material in the fluid to reduce the concentration of contaminants in the fluid, such as by breaking down organic contaminants into non-toxic compounds. A second light source acts directly on living biological entities to sterilize or kill them and thereby disinfect the fluid, and can also serve to activate a semiconductor photocatalyst that in turn causes further damage to biological contaminants. The semiconductor photocatalyst is desirably attached to an optically transmitting fiber substrate in the fluid. The second light source in one embodiment is external to the fluid and illuminates the photocatalyst through transmitting surfaces in a fluid containment vessel. The light sources can comprise respective sets of plural LEDs.

Abstract: A lamp assembly comprising one or more lamp clusters. Each lamp cluster comprises one or more electrodeless UV lamps which are excited by microwaves emitted from a microwave generator. The microwave generator and power supply are enclosed within a housing that is integral with the lamp clusters. The lamp clusters are wholly surrounded by a waveguide. The waveguide, comprising a flange and a distal end cap connected by a mesh, forms an enclosure. The waveguide is essentially UV transparent to allow UV light to pass through but effectively opaque to microwaves in order to substantially contain the microwaves within the waveguide enclosure.

Abstract: A water-borne hazard detection and water treatment system includes sensors (e.g., flow rate, microorganism detectors, and chemical detectors) and can be microprocessor controlled. Microorganisms and/or chemicals are detected within a water distribution system. Treatment areas can be deployed at various stages along a water distribution system. Water entering/passing through a “treatment area” are subjected to light emanating from an ultraviolet laser. UV treated water is provided to its intended point of use after treatment. Filtration can be deployed around input and/or output locations of a system. The system is networkable for communication to remote monitoring agencies (e.g., command and control units) through wired and/or wireless network communications and devices. Networked monitoring and assessment enables rapid deployment of counter measures within affected water distribution systems and populated communities. Emergency distribution shut-off through the distribution network can be based on input from distributed sensors. Multiple treatment systems can be staged.

Abstract: A water-borne hazard detection and water treatment system can include sensors (e.g., flow rate, microorganism detectors, and chemical detectors) and can be microprocessor controlled. Treatment systems can include means to detect microorganisms and/or chemicals within a water distribution system. Treatment areas can be deployed at various stages along a water distribution system, allowing for protection redundancy. During treatment, water enters into and/or passes through a nulltreatment areanull wherein the water is subjected to light emanating from a laser at wavelengths within the ultraviolet range. Microorganisms contained within water are reactive to laser light as they pass through treatment areas and are rendered ineffective. Treated water can then be provided to its intended point of use after treatment. Filtration can also be deployed around input and/or output locations of a system. The treatment systems, including detection means, can be networked to remote monitoring agencies (e.g., command and control units) through known wired and/or wireless network communication means and devices. Networked monitoring and assessment can enable rapid deployment of counter measures within affected water distribution systems and populated communities. Treatment can include emergency shut-off of part of a water distribution network based on input from distributed sensors. Treatment systems can be staged, providing for a system comprising more than one treatment area and associated laser light sources that are coupled, one after the other. Such staging can provide for concentrated redundancy prior to delivery of water to its point of use.

Abstract: A water disinfection system includes a housing having a plurality of risers 207 therein for directing independent columns of water from a manifold at the bottom of the housing. An ultraviolet light source 214 is disposed above the risers to treat the water flowing therein. The UV light source may also be in the form of a fiber optic system (FIG. 4) or a mercury arc lamp including a parabolic reflector 64. Each of the risers can also include notches 304 (FIG. 9) for inducing turbulence to the water flowing thereover in order to ensure that all of the microorganisms receive ultraviolet light. The water flow rate and the light intensity may be adjusted to accommodate different levels of water contamination.

Abstract: A photochemical reactor system employing an optical fibers in the form of a cable to transmit light to solid-supported TiO.sub.2 -containing photocatalyst is disclosed. Light energy is transmitted to TiO.sub.2 -containing particles, chemically anchored onto one or more quartz fiber cores, via radial refraction of light out of each fiber. TiO.sub.2 -containing coating layer minimizes the interfacial surface area of the quartz core and TiO.sub.2 -containing particles and operation with incident irradiation angles near 90.degree. enhance light propagation along the fibers. A maximum quantum efficiency of .phi.=1.1% for the oxidation of 4-chlorophenol was achieved. Fiber efficiency permits the light source to be separated from the photocatalyst.
