Water consumption in the textile industry is high and textile dyes are complex organic molecules that are hard to treat. Every year thousands of tons of dyes are produced worldwide and approximately 10-15% of those remain in wastewater, contaminating groundwater and the environment. Conventional treatment methods present problems of inefficiency, high operational costs and secondary pollution, but magnetic biochar has emerged as a promising material for textile wastewater remediation as it has high adsorption capacity and reusability and is easy to separate using an external magnetic field. Exploring the synthesis, characterization and application of magnetic biochar in textile wastewater remediation, this book details the principles of biochar modification for the incorporation of magnetic nanoparticles. It also looks at the key aspects of pollutant removal mechanisms and summarizes recent advances in magnetic biochar composites, regeneration and reuse. This book bridges the gap between fundamental research and practical applications, and includes a discussion of the economic and environmental feasibility of magnetic biochar technology and its large-scale implementation in textile wastewater management. It is a valuable resource for environmental scientists, engineers and industrial practitioners seeking sustainable wastewater treatment solutions.
