Introduction to Wastewater Treatment Processes illustrates the link between wastewater type and quality, and treatment process selection and performance. Individual chapters concentrate on specific wastewater treatment processes, detailing the chemical and engineering principles behind the process, and further illustrating process implementation by the use of process flow diagrams, photographs and case studies. Two introductory chapters give an overview of current European and U.S. legislation and provide an introduction to a number of typical wastewater treatment works via photographs and process flow diagrams.
