The Effect of Wastewater Treatment Methods on the Retainment of Plastic Microparticles
AI summary Read the abstract
This review examined how different wastewater treatment methods retain or remove plastic microparticles, finding that treatment plant design significantly affects how many microplastics escape to the environment. Advanced treatment processes such as membrane bioreactors outperformed conventional activated sludge systems in removing microplastics.
Microplastics as plastic pieces of ≤5 mm in size, are found in most ecosystems, both terrestrial and aquatic. Many of the microplastics find their way into the environment through the wastewater. For this reason, a knowledge of the microplastic retainment performance of wastewater treatment plants of various design is important. In this regard, several wastewater treatment processes have been studied, including new methods that are still at the development stage. This manuscript reviews the literature on such wastewater treatment methods and their ability to retain microplastics.

The study emphasizes the need for upgrading wastewater treatment systems to better capture these emerging contaminants.
Micro- and nanoplastics removal mechanisms in wastewater treatment plants: A review
AI summary Read the abstract
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.
Recent advances in treatment of microplastics in wastewater
AI summary Read the abstract
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.
