Coagulation technologies for separation of microplastics in water: current status

Journal of Physics Conference Series 2023
Kundi Pu

Summary

This review examines how coagulation water treatment technologies can remove microplastics from water. Conventional coagulation achieves 8-98% removal efficiency while electrocoagulation achieves 8-99%, depending on conditions, offering a potentially effective approach for reducing microplastics in drinking water and wastewater.

Study Type Environmental

Abstract The pollution of the microplastics in the water environment has already been a threat to the whole ecosystem. Numerous MPs are detected in the ocean and the treated wastewater from the wastewater treatment plant. Due to its small particle size, MPs are proven to penetrate through animal cells and cause even fatal harm to the aminal itself. These reports discuss how well the coagulation behaves in MPs’ separation from the water environment and what factors could affect the MPs’ separation efficiency using coagulation. Recent studies about the coagulation used in MPs separation from water has been reviewed, and the MPs removal efficiency for conventional coagulation and electro-coagulation is determined to be 8.28% to 98.2% and 8.24% to 99.4% respectively. The result and conclusion of this study hopefully provide references for people who study the MPs in water and its management strategy in the future.
