  • Publication number: 20200140291
    Abstract: Aspects of exemplary fluid disinfection apparatus and methods are described. One aspect is a disinfection apparatus comprising a body comprising a reflecting chamber, a fluid channel to direct a fluid into reflecting chamber, and radiation source positioned to output a disinfecting radiation into the chamber. The body may include an inlet and outlet. For example, the inlet may extend through the body to receive a fluid at a first velocity; the reflecting chamber may extend along an axis of the body; and the outlet may extend through an end of the reflecting chamber to discharge the fluid from the body. In this example, the fluid channel may direct the fluid from the inlet into the reflecting chamber at a second velocity smaller than the first velocity; and the radiation source may be positioned to output the disinfecting radiation into the reflecting chamber toward the outlet.

  • Publication number: 20190062180
    Abstract: A UV reactor irradiates a flow of fluid with UV radiation. The reactor comprises: a fluid conduit defined by a heat conducting conduit body comprising one or more heat conducting walls for permitting a flow of fluid therethrough; a UV-LED operatively connected to a PCB and oriented for directing radiation into the fluid conduit. The PCB comprises a heat conducting substrate having a first surface. The conduit body is in thermal contact with the first surface of the heat conducting substrate. Heat is dissipated from the UV-LED via the heat conducting substrate, the thermal contact between the first surface of the heat conducting substrate and the heat conducting conduit body, and from the one or more heat conducting walls of the heat conducting conduit body to the fluid flowing through the fluid conduit.

  • Patent number: 7442312
    Abstract: A process for treating a fluid which comprises the step of exposing the fluid to ultraviolet radiation and high-energy ionizing radiation. It has been discovered that combining ultraviolet radiation with high-energy ionizing radiation in the treatment of a fluid results in synergistic performances of the treatment process—e.g., improvement in the inactivation or killing of microorganisms in the fluid, in destruction of organic contaminants and the like. More specifically, fluid treatment performance is improved to a level typically not possible when using ultraviolet radiation and high-energy ionizing radiation separately.

  • Patent number: 6719491
    Abstract: A fluid level control system, particularly useful for controlling the level of water flowing in an open channel. The fluid level control system includes a gate having a flap portion interconnected to a lever portion. The flap portion is rotatable about a first pivot point. The system further includes a frame which is fixed with respect to the flap portion. A linkage interconnects the flap portion and the lever portion, and is connected to the frame at a second pivot point different than the first pivot point. Under changing flow conditions in the channel, the present system operates by both: (i) absolute movement of the lever portion and the flap portion, and (ii) relative movement between the lever portion and the flap portion. A fluid treatment system and a method for controlling the level of a flowing fluid may also use such a fluid level control system.
