PROBLEM TO BE SOLVED: To provide accurately injecting ballast water treatment chemicals into ship's ballast water and reducing the size and cost of dosing equipment.;SOLUTION: A flowmeter 2 for measuring the flow rate of ballast water flowing in the ballast piping 1, a dosing piping 6 including a dosing pump 7A for injecting a ballast water treatment chemical into the ballast piping 1 from the medication tank 5, and ballast water treatment Vessel ballast water treatment dosing system comprising a TRO meter 4 for measuring TRO concentration of ballast water to which a drug is added, and a control device 9A for outputting a dosing signal based on the measurement values of the flow meter 2 and the TRO meter 4. A flow control valve 10 is provided on the downstream side of the chemical feed pump 7A of the chemical feed pipe 6. A medicine return pipe 11 branched from the medicine injection pipe 6 between the medicine injection pump 7A and the flow control valve 10 and having a tip connected to the medicine tank 5 or the upstream side of the medicine injection pump of the medicine injection pipe is provided . The controller 9A outputs a chemical injection signal for controlling the opening degree of the flow control valve 10.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
