ClearMicro- and nanoplastics removal mechanisms in wastewater treatment plants: A review
This review examines how conventional wastewater treatment plants remove micro- and nanoplastics, and evaluates advanced technologies like membrane filtration and electrocoagulation that could improve removal rates. While existing treatment plants can capture most microplastics, they still release significant quantities into waterways through their enormous discharge volumes. The study highlights that biological treatment steps may also transform microplastics in potentially harmful ways that need further investigation.
