Removal of microplastics and nanoplastics in water treatment processes: A systematic literature review

Researchers systematically reviewed 103 studies across 26 water treatment plants in 12 countries to assess how well various technologies remove microplastics and nanoplastics from drinking water, finding that while coagulation, filtration, and advanced treatments help, significant gaps remain. The review identifies that no single process achieves complete removal, leaving microplastics as a persistent contaminant in treated water supplies.

Removal of microplastics in unit processes used in water and wastewater treatment: a review

This review evaluates various water and wastewater treatment technologies for their ability to remove microplastics, including filtration, coagulation, and advanced oxidation methods. The authors found that while conventional treatment plants can remove a large percentage of microplastics, significant quantities still pass through into treated water. The study calls for combining multiple treatment steps and developing new technologies specifically designed to capture micro- and nanoplastic particles.

Review of Advanced Water Treatment for Removal of Nanoplastic Pollution

This review evaluates drinking water treatment technologies for removing nanoplastics, finding that combined coagulation, flocculation, and filtration achieves up to 99.9% removal efficiency. As nanoplastics are detected in drinking water globally and cannot be degraded in the environment or human body, identifying effective removal processes is directly relevant to protecting public health.

Micro- 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.

Microplastic remediation technologies in water and wastewater treatment processes: Current status and future perspectives

This review covers the main technologies for removing microplastics from water and wastewater, including membrane filtration, chemical coagulation, adsorption, biological methods, and advanced oxidation. Each method has trade-offs between effectiveness, cost, and environmental impact, and no single approach removes all microplastics completely. The review emphasizes the urgent need for better removal methods since microplastics have already been detected in human blood and infant feces.
