Two teenagers from Woodlands, Texas invented a device that could help address one of the most pervasive and challenging forms of pollution on Earth: microplastics.
...
Huang and Ou's device is remarkably small, about the size of a pen. It's essentially a long tube with two stations of electric transducers that use ultrasound to act as a two-step filter.
As water flows through the device, the ultrasound waves generate pressure, which pushes microplastics back while allowing the water to continue flowing forward, Ou explained. What comes out the other end is clean, microplastic-free water.
The two teens tested their device on three common types of microplastics: polyurethane, polystyrene, and polyethylene. In a single pass, their device can remove between 84% and 94% of microplastics in water, according to a press release.

(18,048 posts)The gist is that while Brita makes no claims to remove microplastics, some of their filters (including the faucet filter) are rated and 99.7% effective against particles sized smaller than microplastics.

I would expect Brita's major competitor(s) have similar results. I checked Brita because I have used it for years.
(Posting this because with the recent focus on microplastics, I may not have been the only one wondering about whether my filtering system is protecting me and how much.)
I expect these young people's invention has potential uses for water other than drinking water, so it is a great achievement and valid award for sure.

If this truly is a unique "first" it should be impossible for any company to produce prior art proving they did this before the teens, & the teens would own the intellectual property rights.

(37,094 posts)So I'll read the press release instead. The article at the link makes you register and until you do that, you have this big popup blocking the story. Thanks for mentioning the press release.
Here's what I've done about microplastics since it became known as a problem. First, years ago I posted a number of articles on how certain tea bags have microplastics in them, so I urged everyone to use tea bags made with another method. If you have some with microplastics as part of their production, then just open the tea bag and boil it as loose tea. Thanks to IrisBlue for that suggestion.
For water, I filter through a Brita filter. Then I boil it, because there was an article here saying how boiling the water gets rid of around 90% or more of the microplastics. I don't think my filter gets rid of the microplastics, so until I can get the kind of filter mentioned above, I'll continue with this.
I even use the boiled water for my ice cubes, which I make instead of letting the machine make it.
Can't wait until this process/design in the OP is ready for the marketplace.

Copy the articles URL
Go to the archive site
Paste the URL into the text box
Youll usually get the article you want.
Sites let Google and others access the articles to drive clicks but keep the paywalls for everyone else.
They cant have it both ways.
This site lets you try various forms of archive.

Sometimes, it just involves disabling javascript or running a readablilty script to get past nags.
Some of these sites do just that.

(37,094 posts)I always wondered how people did that. I'm gonna' try that a little later on tonight. Thank you for writing that out; hopefully it will help more people than just me.
