Removal of microplastics via drinking water treatment: Current knowledge and future directions

This review examines what is currently known about microplastics in drinking water systems and how well existing water treatment processes remove them. Researchers found that while conventional treatment steps like coagulation and filtration do reduce microplastic levels, significant amounts can still persist through to tap water. The study calls for more research into optimizing treatment processes and developing monitoring strategies specifically targeting microplastic contamination in drinking water.

Removal efficiencies of microplastics of the three largest drinking water treatment plants in Bangladesh

Researchers evaluated the three largest drinking water treatment plants in Bangladesh and found that while conventional treatment removed a significant portion of microplastics, treated water still contained plastic particles. Removal efficiency varied depending on the treatment process used, with some plants performing better than others. This highlights that current water treatment infrastructure may not fully protect people from microplastic exposure through drinking water.

Occurrence and fate of microplastics at two different drinking water treatment plants within a river catchment

Researchers investigated the occurrence and removal of microplastics at two drinking water treatment plants located on the same river in the Czech Republic. The study found that microplastics were present in raw water at both facilities and that treatment processes reduced but did not fully eliminate microplastic contamination, with removal efficiency varying by treatment technology.

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.

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.
