The Wall Street Journal's blog "Ideas Market" features the "ballast blaster," co-created by Junru Wu, professor of physics, a system that, through the use of ultrasound, has been shown to kill virtually all E. coli and other bacteria as well as creatures that elude filters, including water fleas, plankton and zebra mussels. It works by causing gas bubbles within the organisms to violently vibrate, rupturing key structures. Ballast water from international cargo ships has been introducing invasive species into the Great Lakes and elsewhere, which the new method could manage without the use of chemicals.
