The treatment of wastewater from industrial production and processing processes is subject to special requirements. The origin and composition of this wastewater typically necessitate pre-treatment before it can be discharged into a public sewage treatment plant. In cases of direct discharge, the use of specific treatment methods is required. This book provides an overview of possible process technologies for industrial wastewater treatment and their application in selected industrial sectors. Starting from the legal requirements, important planning fundamentals for integrating environmental protection measures into industrial processes are conveyed. The following chapters delve into the various treatment methods in more detail. The final part of the book focuses on selected industrial sectors and the process technologies for their wastewater treatment. The continuing education series 'Water and Environment' covers selected specialized content from the fields of hydraulics and water engineering, waste management, and urban water management, including the subfields of wastewater and water supply.
