The controller (66) controls the operation of the controller (6).

In the ballast water treatment system having the above-described structure, if the neutralizer supply passage 514 is blocked by a foreign substance, the neutralization agent supply passage 514 is cleaned. If the measured pressure measured by the pressure sensor 515 is greater than the set pressure, it is determined that foreign substances as much as necessary for cleaning are accumulated in the neutralizing agent supply passage 514, and the valve control module 614b controls the opening / To be opened in the BC direction. When the on-off valve 513 is opened in the BC direction, the pressurized air module 641c controls the operation of the air pressurizer 521 so that high-pressure air is supplied to the neutralizer feed path 514. The high-pressure air supplied to the neutralizer supply passage 514 pushes the foreign matter of the neutralizer supply passage 514 out of the discharge pipe 4 to prevent the neutralizer supply passage 514 from clogging.
