ClearMicroplastic removal and management strategies for wastewater treatment plants
This review examines how well different wastewater treatment technologies remove microplastics and what management strategies can improve performance. While conventional treatment plants can remove a large percentage of microplastics from water, the particles often end up concentrated in sewage sludge that gets applied to farmland. The study highlights the need for advanced treatment options and better management of biosolids to prevent microplastics from simply being transferred from water to soil.
Microplastics removal through water treatment plants: Its feasibility, efficiency, future prospects and enhancement by proper waste management
Researchers reviewed over 80 studies on water treatment plant performance and found microplastic removal ranges widely — from 16% in basic primary treatment up to near 100% with advanced membrane systems — but a major flaw is that removed microplastics concentrate in sludge, which can re-enter the environment. The review recommends optimizing coagulants and sludge treatment to prevent microplastics from simply being relocated rather than eliminated.

The findings highlight the need for advanced treatment methods to prevent microplastics from reaching waterways and ultimately human water supplies.
Conventional and Advanced Treatment Technologies for Microplastics in Water Treatment Facilities
This review evaluated both conventional and advanced water treatment methods for removing microplastics from wastewater. Researchers found that while techniques like coagulation, filtration, and membrane bioreactors can remove most microplastics, treatment plants still release significant quantities due to the sheer volume of water processed, and microplastic-laden sludge applied to farmland creates another pathway for environmental contamination.

The study suggests that advanced treatment approaches such as membrane filtration and advanced oxidation processes show promise for improving microplastic removal efficiency from wastewater.
Recent advances in treatment of microplastics in wastewater
This review examines current methods for removing microplastics from wastewater, including conventional treatment processes and newer advanced techniques. Researchers found that while standard treatment plants can remove a significant portion of microplastics, many particles still pass through into waterways, and the captured plastics often end up concentrated in sewage sludge. The study highlights the need for improved treatment technologies to more effectively address microplastic contamination in water systems.

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.
Microplastics removal in wastewater treatment plants: A review of the different approaches to limit their release in the environment
This review examines how wastewater treatment plants handle microplastics, finding that while some plants remove up to 99% of microplastics from water, they concentrate the removed plastics in sewage sludge. When that sludge is spread on farmland as fertilizer, over 65% of the captured microplastics can re-enter the environment and potentially contaminate crops and groundwater. The authors argue that treatment plants should be reimagined as key barriers against microplastic pollution, with targeted technologies added at strategic points in the treatment process.
