Ultrasound Waves Offer Hope for Microplastic-Free Water.
Scientists have developed a new method of cleaning microplastics from water using high-pitched sound waves. The new water-scrubbing technology relies on a technique called “acoustic focusing” which uses sound waves to focus or concentrate particles in a certain perimeter. The method can theoretically remove both large and small microplastic particles using a unique two-step process, effectively making plastic-tainted water safe to drink. The researchers will need to do more experimentation before implementing the system in the real world.
