The book is unique in highlighting the issue of wastewater as one of the important environmental issues. The uniqueness also lies in exploring the concepts of converting waste into resources in the form of bioenergy, biofertilizers through various biological methods. Given the international scenario, the chapters of this book are designed to include both anaerobic and aerobic methods of resource recovery from the industrial wastewater. The book is a step toward design with nature and the concept of green chemistry. Waste menace is one of the most voiced and unsolved problems in the entire world. The whole world is facing the threat of water pollution, soil pollution/ land pollution, odour pollution from the growing waste. Though we find many missions and programs at international, national, and regional level to solve the waste associated issues, this is mostly in context with the solid fraction of the waste. Very little is being done to manage the liquid part of the waste or what we call the wastewater. The conversion of wastewater has the potential to be converted to energy in the form bioenergy, bio-fertilizers, electricity, nutrient recovery, etc. The use of sludge as biofertilizers solves the problem of sludge management on the one hand and production of organic crops on the other. The biological treatment methods like sludge treatment gives the farmers the source of biofertilizers and organic manure for the plants. In the present scenario, energy crisis is also one of the issues that we are facing particularly in context with the thermal power plants which are environmentally highly polluting. Through various techniques like microbial fuel cells or biohydrogen, we get a source of cleaner energy. So, through this book, we try to produce the content and information to give the audience an understanding of the waste water as one of the environmental and health issues and mitigation strategies. The book gives a sufficient understanding of how waste can be turned into a resource.

This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
