What have we known so far about microplastics in drinking water treatment? A timely review
This review summarizes research on microplastic occurrence and removal in drinking water treatment, covering both laboratory and full-scale studies through August 2021. Researchers found that conventional treatment processes like coagulation-flocculation, membrane filtration, and sand filtration are generally effective at reducing microplastics in water, though results vary widely depending on conditions. The study identifies key factors influencing removal efficiency and highlights the need for further research on nanoplastics in drinking water.

Rapid sand filtration for <10 μm-sized microplastic removal in tap water treatment: Efficiency and adsorption mechanisms
Researchers tested a sand filtration system for removing very small microplastics (under 10 micrometers) from tap water and achieved a 98% removal rate. The sand captured microplastics through a combination of physical trapping and chemical bonding, and backwashing successfully regenerated the filter by removing 97% of captured particles. This is a promising finding because most existing water treatment technologies struggle to capture the smallest microplastics, which are the ones most likely to be absorbed by the human body.

Removal efficiency of micro- and nanoplastics (180 nm–125 μm) during drinking water treatment
Researchers tested how effectively standard drinking water treatment processes remove micro- and nanoplastics ranging from 180 nanometers to 125 micrometers. They found that coagulation and sedimentation alone removed less than 2% of plastic particles, while granular filtration was far more effective, achieving 87% to nearly 100% removal depending on particle size.

The study also discovered that UV-based disinfection can fragment remaining microplastics into even smaller pieces and increase water toxicity, suggesting current treatment methods may need improvement.
