Abstract: A liquid treatment plant has a tank 10 within which is mounted a tubular treatment chamber 11 having its axis generally vertical and arranged to allow liquid to flow from the tank 10 into the lower end 18 of the chamber and upwardly therethrough. The upper end of the chamber 11 is arranged as a weir over which liquid may flow into an outlet duct 26. A hollow core 27 is disposed co-axially within the chamber 11 and has its upper end also arranged as a weir so that liquid may overflow into the core. The lower end of the core 27 is connected to the outlet duct 26 and UV disinfection treatment lamps 22 are disposed within the annular flow passage between the chamber wall and the core.

Abstract: A method and apparatus are disclosed for using ultrasonic energy in conjunction with an ultraviolet water sterilization system. An ultrasonic transducer assembly (36) is placed in or around one end of the sterilization chamber for producing the ultrasonic energy. Ultrasonic vibrations are then applied automatically on a regular and intermittent basis to clean the components within the sterilization chamber and disrupt the chemical and physical action which causes scaling due to dissolved minerals and organic materials in the water. The ultrasonic vibrations cause a preventive cleaning action by the streaming and stirring of the water. Actual cleaning action is also created by cavitation and sweeping actions. The sweeping action is accomplished by frequency modulation which, by creating varying hot and cold spots within the sterilization chamber, allows for a uniform cleaning of a quartz sleeve (26) encasing a UV lamp (16) within the sterilization chamber. Ultrasonic vibrations also create a germicidal action.

Abstract: The present invention provides an apparatus and method for accomplishing fluid disinfection by passing fluid flow through a uniform array (3B) of ultraviolet lamps having cross sections perpendicular to the direction of fluid flow that define channels (8) for the fluid flow. Positioned next to the end of each lamp (5) at the entrance of the fluid flow are triangular shaped delta wings having surfaces inclined at an angle to the direction of fluid flow. The interaction of the fluid flow with each delta wing creates a pair of vortices (10) that rotate in the same direction or in directions opposed to each other. The counter-rotating vortices (10) reinforce each other to minimize dissipation of their mixing strength as they move down the channel (8). Due to these co-reinforcing properties these counter-rotating vortices (10) more promote efficient mixing of the fluid which is required to achieve more efficient use of the light in the UV disinfection systems, along with heat and/or mass transfer in chemical reactions. Although the present invention is described in particularity as embodied in a UV reactor system, it will be understood by those skilled in the art that the present invention has equal applicability to other types of arrayed flow systems in which increased fluid mixing is desired.

Abstract: Turbulent mixing in a UV system is increased by positioning one or more ring-shaped devices, such as washers, at one or more predetermined locations on the exterior surface of each lamp unit in the system. The washers may have the same or different diameters. Turbulent mixing is also increased by retaining the upstream end of each lamp unit in a ring-shaped device, alone or in combination with washers positioned on each lamp unit exterior surface as described above.
