Mia Heller of Virginia said she got the idea after learning that government agencies were not funding filtration programs
That's awesome. "What, nobody's working on it? okay watch this-"
The final result? A filtration system about the size of an average home appliance that removes roughly 95.5% of microplastics — a level that is competitive with many current filtration methods.
Heller’s system uses a magnetic liquid called ferrofluid. As water passes through the system, the ferrofluid attaches to microplastic particles. A magnet then pulls the contaminants out of the water, leaving cleaner water behind.
The process also allows most of the ferrofluid to be collected and reused, which could help keep costs down over time.
“The result is an affordable, low-waste filtration system without the use of a solid membrane,” Heller said.
I wonder how the mechanical process actually works. Very interesting.
