Hazards and treatment of ship ballast water:

All ocean-going vessels must use ballast water for stability. This water usually contains marine microorganisms, such as plankton, algae, bacteria, and eggs, cysts and larvae of various organisms.

After the ship arrives at the port, it will discharge ballast water. If it is not treated, it will affect the local marine environment, infringe on local species, and play a serious role in damaging the local ecosystem.

In order to meet the requirements of the international marine organization on the discharge of ballast water, ultraviolet sterilization is used to kill microorganisms in the water, so as to minimize the pollution and damage of ballast water to the local marine environment.
