Right now the cellulose filters are still in the testing phase, which is why Sousa will be installing plastic biosand filters for this trip.
“This group (Pure Water for the World) has implemented biosand filters before and it’s something I would drink from myself,” Sousa said in a press release announcing the grant.
When conditions allow, Sousa and his group will also take water samples to see how effectively the existing filters are working, which will help them as they try to develop new, better filters back in Maine.
“On average, 5,400 people die every day due to lack of clean water, and most filters that are out there today cost a lot of money and aren’t biodegradable,” Sousa said. “With our filters, since they’re biodegradable, they won’t affect the environment by leaving chemicals behind when they break apart.”
