Study on the corrosion effect of ballast tank caused by ballast water treatment of hydroxyl radical

  • Received Date: 2014-06-05

  • The thesis presents the study of the situation that hydroxyl radical (OH) may cause the corrosion of ballast tank material in the process of ballast water treatment. Under the highest using concentration of hydroxyl radical, the materials, such as low-carbon steel, stainless steel, and Non-metallic, are commonly used in the ballast tank to evaluate the corrosion influence that ballast water makes on the materials of ballast tank in the pre-and post-treatment testing. The result showed that the corrosion effect of the hydroxyl radical on the metal and non-metal materials does not increase obviously when used in the system of ballast water treatment to effectively kill the exotic pests, which meets the requirements of IMO. It is safe for ballast tank wall metal to utilize the hydroxyl radical in the ballast water treatment. The study result holds a great significance for the anti-corrosion design of the ballast tank and the popularization as well as the application of this ballast water treatment system on board.
