<P>PROBLEM TO BE SOLVED: To provide a treatment system of ship ballast water which is compact, does not require a large amount of electricity, is safe, and facilitates maintenance. <P>SOLUTION: The treatment system of the ship ballast water includes: a water intake part 1; a main line 2; and a ballast tank 3 mounted at the end of the main line 2. A bypass line 5, in which a disinfectant solution supply device 6 filled with chlorine disinfectant S is installed, is annexed to the downstream side rather than a first liquid feed pump 4 of the main line 2, and is branched into a supply line 5A merged in the main line 2 at the downstream side of the disinfectant solution supply device 6, and a return line 5B for returning to the disinfectant solution supply device 6. Further, a first chlorine concentration sensor 13 is installed right in front of the ballast tank 3 of the main line 2, and a flow volume adjusting bulb 15 is installed in the return line 5B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
