A filter free inTank™ ballast water treatment solution for high ballast dependent ships.
In general, to date the treatment or disinfection of ballast water is directly connected and in parallel with cargo activities in Port. This timing seems logical as cargo is discharged or loaded and the weight differential must be compensated by port water pumped to the ballast tanks. In reality this practice poses some operational challenges for high ballast dependent ships.
The paper discusses a common aspect of many fully type approved inline ballast water treatment systems. Inline ballast water treatment systems interrupt main ballast water flow with a filtration mechanism. This introduces operational and commercial challenges for time-critical high ballast dependent ships. Inline systems also treat ballast water in Port, an inconvenient time and place due to various factors in play during port calls.
An alternative “second generation” solution is introduced. Treatment in the tanks during ships voyage elegantly avoids operational and commercial risks for high ballast dependent ships. An inTank treatment based on recirculation and active total residual oxidant (TRO) monitoring also introduces the ability to control biological regrowth on long voyages. The best confidence of regulatory compliance with the least impact on vessel operations.
