Microchlorine generation for anti-biofouling

摘要

A method and an apparatus for retrofit hydrolization of seawater for production of halogen biocides in situ. A method for effecting an in situ generation of biocide as an aid in anti-biofouling of a device disposed in a volume of salt water includes a) associating a cathode electrode to the device; b) associating an anode electrode to the device with the anode electrode spaced apart from the cathode electrode; and c) hydrolyzing one or more components in the volume of salt water to generate a halogen biocide at the anode electrode with the biocide flowing from the anode electrode away from the cathode electrode as a biocide film, the film responsive to a physical arrangement of the associations of the electrodes with the device.

1. A method for effecting an in situ generation of biocide with respect to an external surface of a device disposed in a volume of salt water, the volume greater than a displacement volume of the device, the method comprising the steps of:
a) associating a cathode electrode to the external surface of the device; b) associating an anode electrode to the external surface of the device with said anode electrode spaced apart from said cathode electrode; and c) hydrolyzing one or more components in a portion of the volume of salt water adjacent to the external surface which generates a halogen biocide at said anode electrode with said halogen biocide flowing from said anode electrode away from said cathode electrode within a biocide layer, said biocide layer responsive to a physical arrangement of said associations of said electrodes with the device.
