Title:
BALLAST WATER CONTROL DEVICE AND METHOD FOR CONTROLLING BALLAST WATER TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/110154
Kind Code:
A1
Abstract:
Provided is a ballast water control device having a chemical liquid feed device 2 connected partway along a ballast water feed line 1, a mixing part 4 provided at a location at which a chemical liquid feed line 3 is connected, and a TRO meter 5 provided across a sampling pipe 6 connected to the terminal end 4B-side of the mixing part 4. The TRO meter 5 is capable of transmitting the result of measurement by the TRO meter 5 to a control mechanism 10. The control mechanism 10 is capable of controlling the chemical liquid feed device 2 on the basis of the value of measurement by the TRO meter 5. The position of the distal end of the sampling pipe 6 extends towards the ballast tank side by at least three times the diameter (d) of the ballast water feed line 1 from the terminal end 4B of the mixing part 4. According to this ballast water control device, it is possible to determine an optimum amount of a chorine-based killing agent to add, and to control the ballast water through a simple structure.
