The invention relates to the provision of ship equilibrium water of the treatment apparatus of the electrolysis method.
The apparatus includes a plurality of ballast tanks 90, 100 the ship equilibrium water flows, and a side stream of the ship equilibrium water supplied to the multiple ballast tanks 90 and 100, and the main stream to supply the ship equilibrium water to the side stream, side the electrolysis of the electrolytic cell 50 the stream, and a first salinity measuring means for measuring the salinity of the ship equilibrium water side stream flowing into the electrolytic cell 50, and flows to at least one of the ballast tanks 90, 100 a second salinity measuring means for measuring the salinity of the ship equilibrium water, when salinity measured at first salinity measuring means is smaller than the threshold, a plurality of on the basis of salinity measured at second salinity measuring means a controller for controlling so as to supply the ship equilibrium water to the electrolytic cell 50 from one of the ballast tanks 90 and 100 are composed of, even if the inflow is low salinity water, effectively electrolyzed It can ship equilibrium water electrolysis processing equipment.
