Summary
The present paper reports a study on the shock sterilization technique of ships’ ballast water. In order to expose cell suspension to strong shock waves, a gas gun experiment was carried out. In this experiment, shock waves in the suspension of a marine Vibrio sp. were generated by collision between an aluminum suspension container and an impactor plate accelerated by the gas gun. The changes of shock pressure in suspension were measured by piezofilm gauges and compared them to computational results. The visualization of shock waves in water was carried out by shadowgraph method, and the marine Vibrio sp. was observed with an electron microscope. In addition, the affect of free radicals was also investigated using VitC-Na 2%. It was found that both the dynamic action of shock pressure and the chemical reaction in suspension induced by shock waves were closely related to inactivation of the marine Vibrio sp. at an impact velocity lower than about 200 m/s.
