Ultrasound Cleans Polluted Water, Makes Catfish Tastier
One solution to the world’s water pollution problems could be something you can’t taste, touch, see, smell, or hear. Especially hear. Ultrasound, the range of frequencies beyond the limits of human hearing, is starting to emerge as an effective water treatment that is more sustainable than chemical dosing. Researchers are discovering that ultrasound performs well on algae, and that’s only the beginning. Ultrasound can remove a variety of pollutants in water, including those that affect the taste of America’s favorite fish, the catfish.
