Abstract: A solution for treating a fluid, such as water, is provided. An ultraviolet transparency of a fluid can be determined before or as the fluid enters a disinfection chamber. In the disinfection chamber, the fluid can be irradiated by ultraviolet radiation to harm microorganisms that may be present in the fluid. One or more attributes of the disinfection chamber, fluid flow, and/or ultraviolet radiation can be adjusted based on the transparency to provide more efficient irradiation and/or higher disinfection rates. In addition, various attributes of the disinfection chamber, such as the position of the inlet(s) and outlet(s), the shape of the disinfection chamber, and other attributes of the disinfection chamber can be utilized to create a turbulent flow of the fluid within the disinfection chamber to promote mixing and improve uniform ultraviolet exposure.

Abstract: An object of the present invention is to efficiently sterilize microorganisms present in or on a surface of a liquid. Plasma is generated in a vicinity of or in a manner to make contact with a liquid whose pH value is adjusted to become 4.8 or lower, more preferably 4.5 or lower. The plasma is generated in an atmospheric gas containing nitrogen, e.g., in the air. Superoxide anion radicals (O2−.) that are generated by the plasma react with protons (H+) in the liquid to form hydroperoxy radicals (HOO.). Further, nitrogen and oxygen included in the air are combined together by the action of plasma to form nitrogen oxide such as nitric oxide (NO.). The nitric oxide (NO.) combines with the hydroperoxy radicals (HOO.) to become peroxynitrite (ONOOH(ONOO−)) having a high microbiocidal activity.

Abstract: A laser device is disclosed that provides at least an ultraviolet laser beam and preferably both an ultraviolet laser beam and a visible laser beam. The laser device includes a semiconductor laser device (e.g. a laser diode) to generate visible laser light which is coupled into a frequency doubling crystal taking the form of a single crystal thin film frequency-doubling waveguide structure. The single crystal thin film frequency-doubling waveguide converts a portion of the visible light emitted by the laser diode into ultraviolet light. Both visible and ultraviolet laser light is emitted from the waveguide. As an example, the single crystal thin film frequency-doubling frequency doubling waveguide includes a frequency doubling crystal region composed of β-BaB2O4 (β-BBO), a cladding region composed of materials that are transparent or nearly transparent at the wavelength of the ultraviolet laser light beam and a supporting substrate composed of any material.

Abstract: A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.

Abstract: A UV-emitting phosphor and lamp containing same are described. The phosphor is a praseodymium-activated pyrophosphate-based phosphor which may be represented by the general formula (Ca2-x,Srx)P2O7:Pr where 0≦x≦2. The phosphor is excitable by vacuum ultraviolet (VUV) radiation and in particular it may be excited by Xe-excimer discharges and thereby provide a Hg-free UV-emitting lamp. The phosphor exhibits a broad emission in the UVC region in the wavelength range from about 220 nm to about 280 nm with the peak emission occurring in the wavelength range from about 230 nm to about 240 nm. The emission characteristics of the phosphor may be varied depending on the ratio of Sr/Ca.
