  • Ultraviolet marine anti-biofouling systems
    Patent number: 5322569
    Abstract: Biofouling of underwater surfaces by marine organisms is prevented by irradiating the surfaces or the adjacent water with ultraviolet light and adjusting the intensity of the ultraviolet light so as to kill or temporarily stun marine organisms to prevent their attachment to the underwater surface.
    Type: Grant
    Filed: October 8, 1991
    Date of Patent: June 21, 1994
    Assignee: General Dynamics Corporation
    Inventors: James M. Titus, Bernard S. Ryskiewich
  • Method for killing barnacle larvae in water
    Patent number: 5308505
    Abstract: Biofouling of underwater surfaces by marine organisms is prevented by irradiating the water with ultraviolet light and adjusting the intensity of the ultraviolet light so as to kill barnacle larvae to prevent their attachment to the underwater surface. The water is passed through a biocidal chamber having a source of ultraviolet light at an intensity of at least 4000 .mu.watts/cm.sup.2 and at a rate to provide a residence time of at least one minute on the biocidal chamber.
    Type: Grant
    Filed: November 5, 1992
    Date of Patent: May 3, 1994
    Assignee: General Dynamics Corporation
    Inventors: James M. Titus, Bernard S. Ryskiewich
  • Apparatus for controlling marine fouling of salt water coolant heat exchangers, piping systems, and the like
    Patent number: 3984302
    Abstract: Marine fouling of the tubes of heat exchangers, piping conduits, and like apparatus through which sea water flows is controlled with the aid of an assembly mounted in situ within the system at the inlet ends of the tubes which generates chlorine gas by electrolytic action. The chlorine gas is distributed by the flowing sea water through the tubes and prevents the accumulation of marine plant and animal material on the internal surface of the tubes, thus controlling marine fouling.
