Electrochemical removal of microplastics from laundry wastewater
Advanced electrochemical techniques for efficient removal of micro(nano)plastics from laundry wastewater. The solution optimizes electrode materials and process parameters to address a critical gap in treating fiber-rich laundry effluent, offering a new approach for microplastic control across diverse water matrices.
Overview
Microplastics and nanoplastics (MP/NPs) are abundant in laundry wastewater, presenting a significant environmental challenge. This research proposes the use of electrochemical methods—including electroflotation, electrocoagulation, electroadsorption, and electrooxidation—to efficiently remove these contaminants from complex laundry wastewater. By optimizing electrode materials and experimental protocols, the approach aims to deliver high removal efficiency for fiber-rich MP/NPs, advancing sustainable wastewater treatment and opening new pathways for microplastic control across various water matrices.
