A ballast water treatment device includes a filtration device and an irradiation device that irradiates, with ultraviolet rays, filtered water that has been filtered. The filtration device is a device that removes 99.999% or more of L-size organisms having a minimum part size of 50 µm or more, and 90% or more of S-size organisms having a minimum part size of 10 µm or more and less than 50 µm. The irradiation device is capable of sterilizing the filtered water at a flow rate of 250 m 3 /h and a power consumption of 13 kW to eliminate 90% of S-size organisms immediately after a sterilization treatment.
