SYNOPSIS

Industrial wastewater, particularly from sewage and rubber processing, poses a significant environmental challenge due to its high ammonia, organic, and suspended solid content. Conventional treatment methods, including biological treatments, membrane separation, and chemical coagulation, often face limitations such as long retention times, high energy consumption, membrane fouling, and secondary pollution.

This talk explores the use of immobilized iron-copper (nanoFeCu) bimetallic nanoparticles as an advanced nanotechnology-driven solution for treating sewage and rubber wastewater. NanoFeCu oxidizes ammonia into nitrogen gas, effectively reducing harmful pollutants without producing excessive nitrate or sludge. Studies have demonstrated that nanoFeCu-treated rubber wastewater achieved 95.83% ammonia removal within nine hours, bringing it close to the regulatory discharge standard. Similarly, in sewage treatment, optimized flow rates significantly enhanced ammonia removal, while maintaining high removal efficiency for COD, BOD, and total suspended solids.

The presentation will highlight key findings from recent research, including:
•  Optimized nanoFeCu treatment conditions for maximum pollutant removal.
•  Long-Term reusability and stability of nanoFeCu

By leveraging nanoparticle-based remediation, this technology offers a cost-effective, scalable, and environmentally sustainable alternative for wastewater treatment in industrial applications.
