ELECTROLYTIC STERILIZING APPARATUS FOR SHIP BALLAST WATER

An electrolytic sterilizing apparatus comprises an electrolytic module ( 10 ) including an inlet port ( 11 - 1 ) disposed at one end thereof for allowing ballast water ( 40 ) to be introduced therethrough, an outlet port ( 11 - 2 ) disposed at the other end thereof for allowing the ballast water ( 40 ) to be discharged therethrough, a baffle unit ( 20 ) mounted at the inlet port ( 11 - 1 ) side for generating eddy flow, a sensor ( 30 ) mounted at the outlet port ( 11 - 2 ) side for measuring residual chlorine concentration, and a chamber ( 11 ) disposed between the baffle unit ( 20 ) and the sensor ( 30 ), the chamber ( 11 ) having electrode sets ( 12 - 1 ) mounted therein, each of the electrode sets ( 12 - 1 ) including a pair of electrodes ( 12 ), a power supply unit ( 50 ) for supplying power to the electrolytic module ( 10 ), and a connecting unit ( 60 ) including a pump ( 61 ) for introducing and discharging the ballast water ( 40 ), a pipe ( 62 ) connected to the pump ( 61 ), and a valve ( 63 ).
