UV treatment damages the DNA of organisms as ballast water passes powerful lamps, making them unable to reproduce. It depends on efficient filtration because sediment can block ultraviolet light from reaching the organisms.

Ships can also remove oxygen using inert gas or treat ballast water with waste heat from their engines. These methods have trade-offs involving treatment time, cost, tank sealing, and corrosion.
