BALLAST WATER TREATMENT APPARATUS DISCHARGING USING MICRO BUBBLE

摘要

PURPOSE: An apparatus for sterilizing ballast water using micro bubbles is provided to improve the treating efficiency of the ballast water by maintaining the micro bubbles in the ballast water for a long period of time. CONSTITUTION: An apparatus for sterilizing ballast water includes a ballast water flow path, a main line(210), and a micro bubble generating unit(100a). The main line introduces the ballast water into a ballast tank(230). The micro bubble generating unit is in combined with the main line and supplies micro bubbles to the main line. The micro bubble generating unit includes a main body and a rotation inducing and guiding part. The main body includes an air inlet, a water inlet, and a water discharging part discharges water in which the micro bubbles are generated. The rotation inducing and guiding part is arranged in the main body and induces the rotation of water and guides the water to air.
