  • Method for treating ship ballast water
    Patent number: 8123958
    Abstract: A method for treating ship ballast water in which aquatic organisms in the ship ballast water are exterminated by adding hydrogen peroxide or a compound producing hydrogen peroxide in an amount such that a hydrogen peroxide concentration comes to be 10 to 500 mg/L to the ship ballast water, and then providing physical means for causing shear strength and/or cavitation to the ship ballast water.
    Type: Grant
    Filed: February 17, 2006
    Date of Patent: February 28, 2012
    Assignees: Katayama Chemical, Inc., The Japan Association of Marine Safety, Marine Technology Institute Co., Ltd., Laboratory of Aquatic Science Consultant Corporation, M.O. Marine Consulting, Ltd., Mitsui Engineering & Shipbuilding Co., Ltd., Shinko Ind. Ltd.

  • Method for treating ship ballast water
    Patent number: 7618545
    Abstract: A method for treating ship ballast water in which organisms viable in the ship ballast water are exterminated by adding to the ship ballast water hydrogen peroxide or a compound producing hydrogen peroxide in an amount such that a hydrogen peroxide concentration comes to be 10 to 500 mg/L and at least one type selected from a ferrous ion or a compound supplying ferrous ion in an amount such that a ferrous ion concentration comes to be 0.1 to 400 mg/L, catalase in an amount such that a concentration of catalase comes to be 0.5 to 2,500 unit/L and iodine or a compound supplying iodine amount such that an iodine concentration comes to be 0.1 to 100 mg/L.
