This book covers the physical and chemical processes for treating water and wastewater.  The first part describes the fundamental tools for investigating and studying water and wastewater treatment processes. The second part describes processes for removing soluble contaminants from water. The third is concerned with the processes for removing particulate materials from water. These processes (or some subset of them) are often performed in series, and the order of the chapters reflects the order of their appearance in a treatment train.   An extensive chapter on membrane processes closes the book; membrane processes are used to remove both soluble and particulate materials. Compared to the AWWA and MWH books about water treatment which serve more as references, this book is designed as a comprehensive textbook and a teaching tool. While these books concentrate on drinking water treatment, this textbook deals equally with industrial and waste treatment processes and has a heavier focus on detailed application of theory
