In regions plagued by high fluoride contamination, ensuring access to safe drinking water remains a critical challenge. Fluoride Removal using an Al Rotating Anode Electrocoagulation Reactor presents a comprehensive exploration of an innovative water treatment solution based on a rotating electrode electrocoagulation (EC) reactor using aluminium electrodes. This book delves into the underlying electrochemical mechanisms, optimized process parameters, and reactor design that drive the enhanced removal efficiency of fluoride ions from contaminated water. Through detailed experimental studies, isotherm and kinetic modeling, and cost evaluations, the work offers practical insights into the development of sustainable, scalable, and cost-effective defluoridation technologies. Ideal for researchers, environmental engineers, and water quality professionals, this book contributes to the growing body of knowledge aimed at achieving Sustainable Development Goal 6 - clean water for all.
