This book summarizes key findings in hydrogel-based wastewater treatment and outlines their future directions. The book begins with various physicochemical properties and synthesis routes of hydrogels. The book then unveils their potential in contaminant removal from wastewater along with their mechanisms. The kinetics and thermodynamics governing the adsorption processes during pollutant removal are also explored. In addition, the book brings to light the practical applications of hydrogels in diverse scenarios, offering lessons learned from pilot studies and insights into scaling up hydrogel technologies for large-scale treatment. Alongside the removal of heavy metals and organic pollutants, this book also highlights the application of hydrogels in eradication of microbes in wastewater. Besides the challenges faced during the hydrogel application in wastewater treatment, the environmental sustainability of hydrogel applications is also addressed. The book provides readers a roadmap for the future of hydrogel-based wastewater treatment.
