| Abstract Scope |
This work presents the development of biodegradable filtration membranes of sawdust - sargassum biopolymers, for the treatment of highly copper concentrated wastewater. The membranes were integrated into a recirculating electrochemical system designed to enhance removal efficiency. A two-factor, four-level factorial design was employed to evaluate the effect of current intensity and treatment time on removal performance. The optimal operating conditions were 0.2 amperes applied for 10 minutes per 100 mL of wastewater, achieving up to 80% reduction in copper concentration. The system operated under a continuous flow rate of 0.3 mL/min. Water quality parameters were pH, turbidity, conductivity, COD, and copper concentration (measured via atomic absorption spectroscopy and UV–Vis), as well as SEM-EDS characterization of the membranes before and after treatment. The combined use of biopolymer-based membranes and electrochemical processes demonstrates a sustainable and effective approach for copper remediation, contributing to develop scalable, bio-based materials for circular economy. |
