Removal of Microplastics from Wastewater
Summary
Wastewater treatment plants act as both a sink and a source for microplastics, capturing large fractions but still releasing significant quantities into receiving water bodies and concentrating particles in sewage sludge spread on agricultural land. Improving removal technologies at treatment plants is one of the most impactful intervention points for reducing microplastic flux into downstream environments.
This chapter presents a summary of the main characteristics of sewage treatment plants as sink and source of microplastics to the environment, the sampling procedure and isolation and analytical techniques, as well as removal rates and the best available technologies...
