  • Patent number: 9987604
    Abstract: The invention generally relates to an apparatus and a method for mixing of liquids (50) or of particles with a liquid (50). In a volume of liquid (50), a thermal convection flow is generated at at least one surface of the volume of liquid by irradiating IR radiation (30) into the volume of liquid. Thereby it is possible to avoid a depletion zone at the surface and to more accurately measure interactions of the particles with the surface by means of surface-based measurement methods.

    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.

  • Patent number: 8779384
    Abstract: A clean water dispensing device is disclosed. The device includes a pure water tank (10), a sterilization tube (20), a sterilization lamp (30) and a transit tube (32). The pure water tank is fitted into a cold water tank (5) in such a way that a closed space is defined between the cold water tank and the pure water tank. Drinking water is drawn into an inlet port of the sterilization tube and passes through the transit tube before being stored in the cold water tank through an outlet port of the sterilization tube. The closed space is prevented from making contact with outside air, and only drinking water that has been sterilized by the sterilization tube is supplied into the closed space. Therefore, even if cold water is stored in the closed space for a long period of time, there is little possibility of the propagation of bacteria.

  • Patent number: 8747764
    Abstract: An inline intravenous (IV) fluid sterilization system can be located within directly upstream of the patient's access point, downstream of any breach points, so as to ensure fluid sterility. The chamber space between the walls is accessed by a fluid inlet port and a fluid outlet port between which the fluid flows. The inlet port is connected to a conduit/tubing from the fluid source and the outlet port is interconnected with a conduit/tubing that is free of breach points and interconnects to the patient access point. The inner wall allows for transmission of UV light into the fluid space. The walls define a space therebetween that is relatively small radially, allowing for a sufficient flow rate, but providing a large surface area and small fluid depth for exposure to the UV light. The UV light is provided by an elongated lamp within a cavity of the inner wall.

  • Patent number: 7767978
    Abstract: An ultraviolet (UV) water treatment device includes a housing with an inlet and an outlet. Water flows into the housing through the inlet, is exposed to the UV light, and the treated water then flows out of the housing through the outlet. The UV light source is inserted into a quartz tube from above so that the UV lamp can be changed without draining the system. A lower access port is provided in the bottom of the housing. The lower access port includes a seat that contains the lower end of the quartz tube, and further allows a user of the system to remove debris from a broken quartz tube quickly and safely.

  • Patent number: 7763856
    Abstract: An excitation component or arrangement can provide excitation to a moving object so that information is encoded in time variation of light emanating from the object. For example, in each of a sequence of segments, it can provide a respective non-binary excitation spectrum, and the spectra can be different with a non-interference-like transition between them; because the object emanates light differently in response to the different spectra, photosensing results can be obtained that include encoded information about the object. The non-binary spectra could be different intermediate intensities, such as different gray levels or different intensities of one color or could be different colors. The excitation can be provided in a pattern with non-interference-like transitions between regions, and object motion can also be controlled.

  • Patent number: 7683344
    Abstract: An in-line reactor for the treatment of liquids or gasses by light radiation is disclosed. The reactor is made of tube, pipe, or chamber made of a transparent material, having at least one fluid inlet and correspondingly at least one fluid outlet. The transparent material of the tube is selected such that its refractive index is as possible close to the refractive index of the fluid to be treated. Air gap is kept around the outer transparent walls of the reactor, in order to allow for total internal reflection inside the reactor, of light directed into it from a light source in angles of incidence greater than the critical angle. Fluid treatment systems comprising at least one said in-line reactor are also disclosed. Furthermore, method of in-line fluid treatment, and especially of water sterilization and disinfection and aseptic filling of water are disclosed.

  • Patent number: 7683354
    Abstract: A water treating device includes a cylindrical housing having a longitudinal axis, an inlet and an outlet. Water to be treated enters the inlet, flows through the cylindrical housing and out the outlet. A plurality of elongated UV lamps are disposed in the cylindrical housing. The UV lamps extend generally in the same direction as the longitudinal axis of the cylindrical housing, but are disposed in a non-parallel relationship with the longitudinal axis of the cylindrical housing. Typically one end portion of each of the UV lamps is spaced outwardly from the longitudinal axis of the cylindrical housing. Along the length of each of the UV lamps, the distance between the longitudinal axis of the UV lamps and the longitudinal axis of the cylindrical housing varies.

  • Patent number: 7642522
    Abstract: The invention relates to a device for irradiating an absorbing liquid, for example waste water to be disinfected, in a throughflow. Said device comprises at least two radiator units having one cylindrical UV radiation source and three concentric sheaths. A cooling medium for carrying off heat from the UV radiation source flows in a hollow space between the inner and the center sheath. The inventive device allows to use high-performance UV radiation sources and to evenly irradiate the zones of irradiation and prevents floating particles from settling down on the radiator units.

  • Patent number: 7578933
    Abstract: This invention provides a filtration system for home aquaria that uses a closed-circuit pathway having a surface that contacts a flow of water moving between a tank inlet and tank outlet. The surface allows for algal growth thereon, and for transmission of light thereonto so as to provide photosynthetic energy to the algae. The algae acts to scrub contaminants (nitrogenous compounds, for example) as part of its growth cycle, and thereby purify the water. Additional components, such as injected air and filter media can also be provided to the water circuit to enhance algal growth, oxygenate the water and remove particulates. In an illustrative embodiment, the surface is transparent or translucent and a light that transmits appropriate wavelengths (for example, full-visible spectrum) is placed in proximity to the surface.

    Abstract: Multiple UV sterilizers may be connected in series in order to increase the microorganism kill rate. The UV sterilizers are rotatable with respect to other UV sterilizers so that the UV sterilizers may be combined in various configurations in order to adjust a level of UV sterilization and allow combination of UV sterilizers in various configurations. For example, a combination of two or more UV sterilizers may be configured in a first orientation if the UV sterilizers are to be placed in a narrow space, while combination of the same UV sterilizers may be adjusted to another orientation if the sterilizers are to be placed in a large, open space.
