ClearCombining nanofiltration and electrooxidation for complete removal of nanoplastics from water
Researchers developed a two-step water treatment method that combines nanofiltration (a fine membrane filter) with electrooxidation (using electricity to break down pollutants) to completely remove nanoplastics from water. This approach is significant because nanoplastics are too small for many conventional filters to catch, and this system was able to eliminate them entirely.
