BWTS (Ballast Water Treatment System)

The ship’s ballast water treatment system is a facility that sterilizes microorganisms in the seawater filled in the ship’s ballast tank to maintain the ship’s left and right balance.
Ballast water refers to ocean water filled with cargo ships or oil tankers to maintain the ship’s balance when it is not carrying cargo. The seawater loaded at the departure port to maintain the equilibrium of the cargo ship is poured into the local sea when it arrives at the foreign port where the cargo will be loaded, and then returned.
At this time, the seawater loaded at the departure port contains plankton and various aquatic organisms, which proliferate in large quantities in the discharged sea.
This will cause problems that disturb the marine ecosystem
