The ballast water in the ship contains a large number of organisms, including plankton, microorganisms, bacteria, and even small fishes, as well as eggs, larvae or spores of various species. Some of these organisms cannot adapt to temperature, salinity, etc. while following the ship. The factors change and die. But some can survive, and eventually discharge into the new environment with the ship. As a result, organisms or a wide variety of organisms in one water area are transported with ballast water to another geographically isolated water area. If these organisms can grow and reproduce in natural or semi-natural ecosystems or habitats due to lack of natural enemies or other reasons ；

The function of the ballast water system is to inject the ballast water into the ballast water tank or discharge the ballast water from the ballast water tank to achieve the following purposes: The ship maintains proper conditions in different working conditions such as sailing, entering and leaving ports, loading and unloading, and berthing. Displacement, longitudinal and lateral balance of the hull in order to maintain an appropriate center of stability, reduce the excessive bending moment and shear force of the hull, and reduce the vibration of the hull. An important part of the ballast water system is the ballast water filter element;
