Advancing Circular Economy of Water and Wastewater Using Magnetic Nanomaterials

Abstract

Aims: This study explores the potential of magnetic nanomaterials in addressing water and wastewater management challenges through the circular economy approach. Methodology: The study reviews the literature on the use of magnetic nanomaterials in water and wastewater treatment and discusses their unique properties that allow for selective pollutant removal, easy recovery, and reuse, as well as resource recovery. Results: Magnetic nanomaterials have shown promise in enhancing the efficiency of existing treatment processes, facilitating energy recovery, enabling water reuse, precious metals recovery, and aiding in the effective recovery of nutrients. However, challenges such as long-term toxicity, optimization, and regulation need to be addressed to facilitate widespread adoption. Conclusion: Integrating magnetic nanomaterials into water and wastewater treatment processes holds significant potential for advancing the circular economy of water and wastewater. Applying magnetic nanomaterials in water and wastewater treatment can minimize waste generation, promote resource efficiency, and offer practical solutions to remove pollutants that are challenging to remove using conventional methods.
