In the case of the United States, the installation of a ballast treatment system , So that shipowners are also ordering to build a ballast treatment system.

Therefore, the ship ballast water treatment system should be constructed in all ships going to other waters and the stability should be certified. Therefore, it is costly for the ship owners who order the ship construction, There is a limit to sacrifice the loading space, and the cost of logistics also increases due to the limited loading space.

For example, the ship ballast water treatment system can be used for a variety of piping systems for taking in, supplying, processing, storing and discharging seawater, a water intake system such as a pump, an electrolytic bath or ultraviolet reactor system for treating seawater, , Filter equipment, various valve mechanisms, and monitoring equipment are installed in the ship, safety design such as explosion prevention and safety equipment must be provided in parallel.

In addition, when operating the vessel in practice, additional costs for operation, maintenance and repair of the ballast water treatment system should be endured and experts for the operation of the ballast water treatment system should be placed on the vessel.

When there is a service request for the ballast water supply from the service demand ship or the demand customer, Toward the service connection end 52 of the mobile terminal.

Then, the connector 402 of the service head 400 is connected to the service connection terminal 52 of the service demand vessel 50.

At this time, the first, second, fourth and sixth valves (V1, V2, V4, V6) and the recovery line open / close valve 312 are closed and the injection path opening / closing valve 202, the third valve V3, Lt; / RTI &gt;

The service equilibrium water stored in the equilibrium water reservoir 10 is sucked by the pump action of the main pump 120 to flow backward through the equilibrium water infusion line 200 and the main inflow line 110, 111 to the main inflow line 110 at the inlet side of the main pump 120.

And then sent to the ballast water service line 300 via the main pump 120.

The worker operates the service valve 404 provided in the service head 400 to open or close or adjust the flow rate, and supplies the service water for service to the service demand vessel 50.

<Service ballast water recovery from vessel, recovery after storage or ocean discharge>

The service demand ship 50 is moved to the service demand ship 50 and the service demand ship 50 is transported from the service demand ship 50 to the service demand ship 50. In the case where there is a service request for recovery of ballast water filled in the ballast tank of the service demand ship, Service connection end 52 as shown in FIG.

The electrolytic water is injected into the main inflow line 110 through the electrolytic water injection line 152 of the sterilization apparatus 140a.

In addition, if necessary, the ballast water recovered from the service demand vessel 50 may be directly discharged to the ocean without being stored in the ballast water storage tank 10. To do so, instead of closing the second valve V2, the seventh valve V7 is opened.

In this case, as described above, the filter unit 130 can be passed or bypassed depending on the state of the ballast water to be recovered. In addition, it can be disinfected through the disinfection device 140a and then discharged or discharged immediately without sterilization treatment. The electrolytic water is injected into the main inflow line 110 through the electrolytic water injection line 152 of the sterilization apparatus 140a. When this treatment is done, it is necessary to neutralize residual hypochlorous acid again before discharging it to the ocean. Therefore, a neutralizing agent is injected into the drain line 72 from the neutralizing agent supply unit 160 through the neutralizing agent input line 162 to lower the total residual oxidizing agent (TRO) concentration below the allowable concentration.

<Ballast water discharge for stored service>

When it is necessary to discharge the service ballast water stored in the ballast water storage tank 10 to the ocean, the first, second and sixth valves V1, V2 and V6, The open / close valve 302 and the recovery line open / close valve 312 are closed, and the third, fourth, fifth and seventh valves V3, V4, V5 and V7 are opened.
