Wastewater Treatment (CABI Concise) – serie

Heavy metal pollution is a major concern for all ecosystems where wastewater is present and it has the potential to harm the health of humans, animals and plants wherever it exists. Remediating the adverse effects of these pollutants is thus a significant global challenge that requires the use of the most up-to-date technologies. After describing the various toxic and negative effects posed to humans and ecosystems by heavy metals, this book explores advanced strategies for heavy metal detoxification through microbiological applications, such as bioreduction, bioaccumulation, immobilization and enzymatic remediation. It also considers the various microbes that can be used for the remediation of heavy metals and how advanced technologies like bioreactor technology, nanotechnology, genetic engineering and Artificial Intelligence can be applied for higher heavy metal removal rates. This book analyses the challenges and limitations of these sustainable microbe-based strategies for the removal of heavy metal pollutants from contaminated wastewater. It also provides a valuable resource for practitioners and professionals involved in human, animal and environmental health and those interested in the direction of future research.

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.
