Emerging contaminants refer to the naturally occurring or synthetic chemicals or substances that have been identified recently and are toxic to human health and environment. These are known as contaminants of emerging concern (CECs). Some major sources of CECs are pharmaceuticals and personal care products, detergents, steroid hormones, industrial chemicals, and pesticides. The complete removal of the CECs requires the use of advanced chemical, physical and biological treatment techniques. Advanced oxidation processes (AOPs) is an emerging chemical technology used for treating wastewater. Ozone, catalyst and UV irradiation are oxidants that combine in AOPs for delivering more efficient wastewater treatment. The CECs have demonstrated low acute toxicity but studies have shown that they may cause significant reproductive effects at low levels of exposure. This book outlines the latest methods for detecting and treating emerging contaminants in water and wastewater in detail. It will help the new readers in foregrounding their knowledge in this area of study.

Water treatment is the process of improving water quality by removing contaminants and other undesired components, so that it becomes suitable for specific end-use. There are two types of water treatment, namely, drinking water treatment and industrial water treatment.The process used for removing contaminants from sewage and wastewater is known as wastewater treatment. The treatment aims at converting the wastewater into effluent so that it can be returned to water cycle. Water reclamation is the process of converting wastewater into water which can be reused. Wastewater treatment plant is the facility where the process takes place. There are various processes which are used for treatment of wastewater, such as phase separation, sedimentation, biochemical oxidation, etc. This book elucidates the concepts and innovative models around prospective developments with respect to water and wastewater treatment. Most of the topics introduced herein cover new techniques and the applications of water and wastewater treatment. This textbook will serve as a valuable source of reference for those interested in this field.
