  • Publication number: 20080006586
    Abstract: Monochloramine is efficiently manufactured by introducing controlled quantities of an ammonia source and a chlorine source in a small side-stream of water in a small diameter pipe under turbulent flow conditions. The ammonia source and chlorine source can be injected in either order and are separated by a sufficient distance to ensure that the first chemical is adequately diffused throughout the water prior to the injection of the second chemical. A sufficient length of a mixing chamber insures that turbulent flow is maintained for a length of time sufficient to thoroughly mix the two chemicals to produce monochloramine. This mixing technique allows for the manufacture of high concentrations of monochloramine at atmospheric pressure without off gassing.

  • Publication number: 20080006587
    Abstract: A method and apparatus are disclosed for injection of carbon dioxide into a process water stream. The method and apparatus allow carbon dioxide injection using any line pressure as it normally exists in a target water stream and produces superior mixing and carbon dioxide transfer results. The benefits of this method and device significantly improve the economics of using carbon dioxide gas to control pH and at the same time reduces the negative impact on the environment caused by the off gassing of carbon dioxide that is not effectively mixed into solution.

  • Publication number: 20070114320
    Abstract: A bandage wrapper having a wrapper with a flanged section having two extensions defining a slot between them for bandage or other wrappable material insertion. The extensions are flared and allow for easier insertion of bandage or wrappable material. Additionally, the wrapper may be secured in a drill chuck or other coupling to a motorized driver.
