PURPOSE: A salt water supplying device for an electrolysis unit of a ballast water treating device is provided to save the cost required for transportation and equipment installation and to improve the efficiency of a space by reducing the volume of a salt water tank. CONSTITUTION: A salt water supplying device for an electrolysis unit of a ballast water treating device comprises a raw water supplying unit (100), a salt water generating unit (210), a mixing unit (300), and a salt water supplying pump (400). The raw water supplying unit supplies salt water of low salinity. The salt water generating unit comprises a salt storage bath and a salt water tank. The salt storage bath generates salt water of high salinity by receiving first raw water from the raw water supplying unit and dissolving salt with the first raw water. The salt water tank stores the salt water of high salinity. The mixing unit mixes the salt water of high salinity from the salt water tank with second raw water to be supplied to an electrolyzing unit. The salt water supplying pump supplies the salt water of high salinity from the salt water tank to the mixing unit. |
