Teens Invent Device that Removes Microplastics with Ultrasound Waves, Winning $50k
A pair of high schoolers invented a unique water filtration device that uses a wall of sound to hold back microplastic particles from running water.
In lab tests, the acoustic force from the high-frequency sound waves removed between 84% and 94% of the suspended microplastic particles in a single pass, and they are using the reward money from a prestigious prize to attempt to scale up their invention.
Without beating a dead horse, microplastic particles are everywhere on Earth—raining down from the jetstream, blowing up to the summit of Everest, and located at the deepest points of the ocean. Once ingested by humans, they have been found to infiltrate every organ that has been examined for them so far.
Addressing this pan contaminant is a monumental challenge, but high schoolers Justin Huang and Victoria Ou of Woodlands, Texas, may have a clever solution.
Using ultrasonic sound waves that move freely through the water, the teens have managed to capture as much as 94% of microplastic contaminants by pushing them away from the water’s outflow point.
Their device is no bigger than a pen and improves on other designs that have tried to use ultrasonic waves to address microplastics in wastewater and drinking water.
“This is the first year we’ve done this,” Huang told Business Insider backstage after receiving their award. “If we could refine this—maybe use more professional equipment, maybe go to a lab instead of testing from our home—we could really improve our device and get it ready for large-scale manufacturing.”
Ou and Huang presented their work at last week’s Regeneron International Science and Engineering Fair (ISEF) in Los Angeles, during which they won the Gordon E. Moore Award for Positive Outcomes for Future Generations worth $50,000.
They also picked up first place in their Google-sponsored category, Earth and Environmental Sciences.
“This is a pretty new approach. We only found one study that was trying to use ultrasound to predict the flow of particles in water, but it didn’t completely filter them out yet,” said Ou, who has known Huang since elementary school.
In developing their device, the pair visited wastewater and sewage treatment plants near their home and asked how they regulated microplastics. The answer they received was somewhat of a surprise: the plant had no such regulations in place. For starters, there isn’t a cost-effective means of doing so, and also the United States EPA doesn’t have regulations for microplastic contaminants in the water.
Ou and Huang believe their technology could be used in wastewater treatment plants like the one they visited, industrial textile plants, and rural water sources. On a smaller scale, it could filter microplastics in laundry machines and even fish tanks.
Justin and Victoria explain their device in the following video.
The good news about this story is the fact that young people are asking questions about the status quo and then doing something about situations they find needing improvement. Today’s John Ku talks about questioning the way things are done. I hope you have a beautiful weekend.

Well done, Justin and Victoria, all they need now is for the big commercial companies to either keep their greedy paws off, or cooperate and not block their invention the way they did for alternatives to petroleum products that have contributed to today’s climate problems.
