Simultaneous electricity generation and filtration of wastewater

https://techxplore.com/news/2023-02-simultaneous-electricity-generation-filtration-wastewater.html

"sandwich-like membrane provide drinking water and generate continuous electricity from wastewater, seawater, and groundwater... filters water at bottom and conductive polymer generates electricity at top... controls direction of water flow. Water flowing perpendicularly to membrane generates direct current by movement of ions in horizontal direction... rejects >95% of contaminants of sizes <10 nm... microplastics and heavy metal removed, and continuous electricity can be generated for >3 h with only 10 µl water"
