Since the ecological and environmental monitoring and protection has been widely addressed and emphasized by academic research and public, the remediation and removal for the pollutants became a critical subject for the Industry, Official and Academy. The state-of-the art technology needs to be comprehensively surveyed covering a wide spectrum of related areas. This book is aimed to fulfill this goal and hopefully will benefit the student, teaching staff, engineers, staffs in the civil corporation and also the public.

This book is divided into 5 chapters and an introduction. In the introduction section, Nitrogen compounds and their toxicity and pollution in the water environment are first addressed and the necessity to remove them from the water body is emphasized. Chapter 1 discusses conventional method and technology of Nitrogen removal from water. Chapter 2 covers conventional Biological method for nitrogen removal. The next three chapters are the essence of this book and maybe the most interesting parts for the readers, in Chapter 3 the authors introduce food industry wastewater treatment from nitrogen compounds. In Chapters 4 and 5 a new approach towards environmental pollution remediation biotechnology by different types of Bio Electrochemical Systems (BES) is presented.
