Pollutant-filtering technology powered by sunlight purifies water fourfold from 2021

Sponge-like gel studied at Princeton University

February 9, 2023  By Ground Water Canada

Heavy metals, oils, microplastics, and some bacteria are among the pollutants that can be filtered from water through a sponge-like gel, providing an alternative for water purification. Researchers at Princeton University are using solar absorber gel technology in which sunlight filters pollutants from water. The updated technology has resulted in almost four times the filtration rate over the technology’s first generation developed two years ago. Technology Networks report | READ MORE
