Sustainable Technologies and Advanced Material for Water Management: An Era of Zero Liquid Discharge presents a comprehensive overview of emerging sustainable technologies, innovative materials, and eco-friendly approaches for wastewater treatment, water purification, recycling, and resource recovery. With increasing water scarcity, rapid urbanization, and industrialization, the development of efficient and environmentally responsible water management systems has become essential. This book highlights the integration of conventional treatment methods with advanced technologies to achieve improved water quality, reduced environmental pollution, and sustainable utilization of water resources.

The book covers a wide range of topics, including conventional and advanced wastewater treatment technologies, nanotechnology applications, green synthesis of titanium dioxide (TiO₂) nanoparticles, biosorbents, biomass-derived activated carbon, and magnetic materials for pollutant removal. It also explores membrane-based treatment systems, photocatalysis, adsorption, advanced oxidation processes, and eco-friendly bio-based materials for efficient water management. Special emphasis is placed on the conversion of wastewater sludge into valuable products such as biochar, biogas, biosorbents, nutrient-enriched fertilizers, construction materials, biopolymers, and specialty chemicals.

Furthermore, the book discusses the potential of nanomaterials and nanocomposites in removing heavy metals, organic pollutants, dyes, pharmaceuticals, and other emerging contaminants. It highlights the importance of resource recovery, water reuse, green chemistry, and Zero Liquid Discharge (ZLD) approaches while addressing challenges related to cost, scalability, operational efficiency, and environmental safety.

This book will serve as a valuable reference for researchers, academicians, postgraduate students, environmental scientists, chemical engineers, water treatment professionals, and industry practitioners working in wastewater treatment, environmental engineering, nanotechnology, and sustainable resource management. It aims to encourage innovative research and technological advancements towards cleaner water, resource conservation, and a more sustainable water-secure future.
