The presence of refractory organic compounds in wastewater is a global problem. Advanced oxidation processes, in general, and the Fenton oxidation process are alternative technologies for wastewater and water treatment. This book gives an overview of Fenton process principles, explains the main factors influencing this technology, includes applications, kinetic and thermodynamic calculations and presents a strong overview on the heterogeneous catalytic approach. It demonstrates that the iron-based heterogeneous Fenton process, including nanoparticles, a new complex solution, is highly efficient, environmentally friendly, and can be suitable for wastewater treatment and industrial wastewater. FEATURES Describes in detail the heterogeneous Fenton process and process applications Analyzes the advantages and disadvantages of different catalysts available and their suitability to specific processes Provides economic analysis of the Fenton process in a ready-to-use package for industrial practitioners for adaptation into already existing industrially viable technologies Promotes a modern solution to the problem of degradation of hazardous compounds through ecological and environmentally friendly processes and the use of a catalyst that can be recycled Explains highly complex data in an understandable and reader-friendly way Intended for professionals, researchers, upper-level undergraduate and graduate students in environmental engineering, materials science, chemistry, and those who work in wastewater management.

Summary: The papers selected for publication in the Special Issue "Urban and industrial wastewater disinfection and decontamination by Advanced Oxidation Processes (AOPs): current issues and future trends" and published in this book, include topics related with (waste)water treatment and its reuse, disinfection, and pollutant degradation, advancing the know-how of the topics or assessing their integration into the new age of the circular economy of water.

Summary: Water pollution from biorefractory pollutants and emerging contaminants is still a very relevant problem worldwide. Examples of these pollutants include disinfection by-products, pharmaceutical and personal care products, persistent organic chemicals, as well as their degradation products. The occurrence of these contaminants in water has raised increasing concern due to their accumulation and persistence in the environment and the threat they pose to the ecological system and human health. In this Special Issue, papers regarding the advancements in materials and processes for use in the electro- and photoelectrochemical removal of different pollutants from water are collected. The synthesis, characterization and application of materials for use in electrochemical or photoelectrochemical techniques are presented, as well as studies concerning catalytic processes and reaction kinetics.
