This contributed volume discusses the current status of the occurrences, fate and transport of persistent pollutants in water and wastewater. This contents compile the state-of-the-art of emerging technologies such as nanotechnology, advanced oxidation process, membrane processes, sorption, etc. for the clean-up of persistent pollutants in water including heavy metals, pharmaceuticals, phenolic compounds as well as microplastics and their by-products. This volume will be useful as a guide for the researchers to build strategies to deal with persistent pollutant. It also discusses the principal aspects of degradation mechanism of the pollutants, toxic by-products and effectiveness of the emerging technologies. This volume will be a useful guide for those working in soil and water protection, and environmental civil engineering.
