Wastewater treatment aims at reducing pollutants by using different treatment methods. To achieve desired performance, it is important to ensure the proper operation and maintenance of the water treatment plant. A number of factors determine the wastewater reuse and include potential revenues, operating costs, resource value and public acceptance of wastewater resources. Membrane filtration, automated variable filtration (AVF) technology, new urban sanitation technology, and urine separating process are some of the advanced technologies used for wastewater treatment. The new urban sanitation technology integrates electro flocculation (Elflox) and anaerobic digestion technologies for treating wastewater. Natural treatment systems are helpful in removing several contaminants such as nutrients, pathogens, micro-constituents, and endocrine disrupting chemicals. This treatment process is extremely effective for water reclamation (or water reuse). This book provides a detailed explanation of the wastewater treatment and reuse technologies. It aims to equip students and experts with the advanced topics and upcoming concepts in the area of wastewater treatment and management.

Wastewater treatment is a process used to remove contaminants from the wastewater in order to convert it into an effluent that can be returned to the water cycle. Some common wastewater treatment technologies include advanced oxidation processes (AOPs), nanotechnology, membrane filtration technology, and automatic variable filtration (AVF) technology. There are various researches being performed in the field of nanotechnology for developing advanced treatments that can decompose toxic substances. The upcoming technologies for wastewater treatment and reuse include fabrication of nanomaterial membranes, using catalysts for decomposing noxious compounds, and using mixed oxides, bimetallic nanoparticles, carbon compounds, metals and zeolites. This book includes some of the vital pieces of works being conducted across the world, on various topics related to wastewater treatment and reuse technologies. The various studies that are constantly contributing towards advancements in this field have been examined in detail. The book will serve as a valuable source of reference to graduate and postgraduate students.

Water which has been used for various domestic, industrial and agricultural purposes, and is not suitable for human consumption is termed as wastewater. Metals, plastics and human excreta are some of the common water pollutants. The processes used to remove these contaminants from water so that it can be returned to the water cycle with minimum environmental impact are studied under the discipline of wastewater treatment. Water treatment techniques include grit removal, settling, aeration, filtration, disinfection, and sludge treatment. Some of the different types of wastewater treatment plants are sewage treatment plants, Leachate treatment plants and agricultural wastewater treatment plants. This book attempts to understand the multiple branches that fall under the discipline of wastewater evaluation and management and how such concepts have practical applications. It elucidates new techniques and their applications in a multidisciplinary manner. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.

Wastewater management is a procedure that is used to remove contaminants from sewage or waste water and convert it into an effluent that can later be reused. The main objective of waste water treatment is disposing or reusing water. The treatment of wastewater takes place in wastewater treatment plants where the pollutants are broken down or removed. The wastewater treatment process involves various steps like phase separation, sedimentation, filtration, oxidation and polishing. The biological processes which are used for treating wastewater include aerated lagoons, activated sludge and slow stand filters. The treatment of wastewater also involves the separation of solids from liquids, by the process of sedimentation. This book provides comprehensive insights into the field of wastewater management as well as its theory and practice. It also presents researches and studies performed by experts across the globe. This book will serve as a valuable source of reference for graduate and post graduate students.
