Removal of Micro/Nano-Plastics from Water by Flotation Technology: A Review
Summary
This review covers flotation technology as a method for removing micro- and nanoplastics from water, explaining how dissolved air flotation, electroflotation, and froth flotation work to separate plastic particles. The authors assess performance data across particle sizes and polymer types and identify remaining challenges for scaling these approaches.
Microplastics (MPs) and nanoplastics (NPs) are brand-new types of persistent contaminants that have lately emerged in the ecosystems owing to the extensive use of plastic items in our daily lives. It has been recognized that these contaminants have many hazardous implications on the environment and on the human health. This has set off alarm bells worldwide to find effective solutions in order to reduce the discharge of MPs and NPs into the environment. Flotation technology isa promising solution to reduce the contents of MPs/NPs in wastewater streams prior to their discharge into the surface water. This review summarizes the risks of MPs and NPs to human health and ecosystems and describes the principles of flotation technology. Furthermore, advances in flotation technology to improve the removal efficiency of MPs and NPs from water are reviewed. Current challenges and future remarks on the flotation technology in removing MPs/NPs from water are also highlighted
