MARINE MICROORGANISM STERILIZATION APPARATUS AND MARINE MICROORGANISM STERILIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To securely kill shellfishes and marine algae while applying a sodium hypochlorite concentration in a concentration having little effect on an environment in facilities utilizing seawater such as a ballast tank and cooling facilities at a plant.;SOLUTION: A sterilization apparatus comprising a first conductor 10 and a second conductor 20 serving as an electrode pair which are adjacent with a space at a predetermined interval and is close, and an electric voltage and current control part 40 for controlling an electric voltage-current applied across the electrode pair controls the generation amount of sodium hypochlorite generated by electrolyzing seawater across the electrode pair and kills a marine microorganism present in seawater across the electrode pair by applying an electroshock. Note that as an example of an electrode, the first conductor 10 is a hollow cylindrical body positioned outside, the second conductor 20 is a hollow cylindrical body positioned inside, and the electrode pair is a dual-structure cylindrical electrode pair.;COPYRIGHT: (C)2009,JPO&INPIT
