Book Description
Written and edited by a team of industry experts, this exciting new volume covers clean energy production from sewage and biomass while achieving a zero-waste strategy. Wastewater treatment plants are critical in protecting both the environment’s resources and human health. A wastewater treatment plant’s technological system focuses not only on the effectiveness of the treatment but on the costs and energy consumption of the entire system. Municipal wastewater treatment produces a significant amount of sewage sludge all over the world. The majority of this sludge’s dry matter content is made up of organic compounds which are not toxic, and they consist of both primary and secondary (microbiological) sludge. There is also a substantial quantity of inorganic substances in the sludge, along with a small quantity of toxic matter. Also, various raw sewage treatment options can include energy production (heat, electricity, or biofuel) to reduce dependence on external energy supply during treatment. The most important options used for energy production from sewage and biomass can use the following approaches: anaerobic digestion, co-digestion, incineration with energy recovery, co-incineration, pyrolysis, gasification, supercritical (wet) oxidation, and hydrolysis. Generally, these processes or methods are cost-effective, but they can still have some setbacks related to the nature of the methods or the raw material used for conversion. There are also operating conditions to comply with to get a successful outcome. This book combines information from many disciplines related to wastewater treatment technologies to show how the circular economy approach can be used to achieve zero waste and produce energy that can be useful for plants and communities. This approach focuses on clean technologies for green energy resources such as biohydrogen, biofuels, and biogas from biomass and sewage sludge for zero waste production. This is aimed to also integrate the issue of energy demand and the one of energy production.

Book Description
Drying Principles and Practice presents the fundamental principles that underlie drying arts as a basis for explaining the behavior of a drying plant. This book begins with an introductory chapter, followed by an account of the phenomena that causes the influence of moisture on its host material and manner in which moisture may be expelled by heat into the humid surroundings. The quantitative description of the way a moist material dries and how it dries under commercial conditions are also provided. The remainder of this text is devoted to surveying less-common methods of drying, moisture-measurement techniques, dryer-control systems, and aspects of the choice and design of industrial dryers. This publication is valuable to engineers, but is also a good source for senior undergraduate and postgraduate students engaged in studies of heat with mass transfer.

Book Description
The principle of the conventional activated sludge (CAS) for municipal wastewater treatment is primarily based on biological oxidation by which organic matters are converted to biomass and carbon dioxide. After more than 100 years’ successful application, the CAS process is receiving increasing critiques on its high energy consumption and excessive sludge generation. Currently, almost all municipal wastewater treatment plants with the CAS as a core process are being operated in an energy-negative fashion. To tackle such challenging situations, there is a need to re-examine the present wastewater treatment philosophy by developing and adopting novel process configurations and emerging technologies. The solutions going forward should rely on the ways to improve direct energy recovery from wastewater, while minimizing in-plant energy consumption. This book begins with a critical overview of the energy situation and challenges in current municipal wastewater treatment plants, showing the necessity of the paradigm shift from removal to recovery in terms of energy and resource. As such, the concept of A-B process is discussed in detail in the book. It appears that various A-B process configurations are able to provide possible engineering solutions in which A-stage is primarily designed for COD capture with the aim for direct anaerobic treatment without producing excessive biosludge, while B-stage is designated for nitrogen removal. Making the wastewater treatment energy self-sustainable is obviously of global significance and eventually may become a game changer for the global market of the municipal wastewater reclamation technology. The principal audiences include practitioners, professionals, university researchers, undergraduate and postgraduate students who are interested and specialized in municipal wastewater treatment and process design, environmental engineering, and environmental biotechnology.

Book Description
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.

Book Description
Sewage sludge is the product resulting from wastewater treatment plants and aquaculture systems. It is an abundant waste biomass, as its production keeps increasing due to population growth, particularly in developing countries and intensified wastewater treatment plants in the developed world due to industrialisation. Effective management and handling of sewage sludge in an environmentally friendly way has become a matter of increasing importance globally, due to the potential health risks on the environment. Importantly, sewage sludge contains large amounts of organic components and nutrients; hence, resource recovery from such an abundant biomass is necessary. This comprehensive book presents an assessment into the impact of sewage sludge on the environment and provides the various treatment options for converting the sludge into useful resources. Biochemical (or biological) and thermochemical (or thermal) methods of sewage sludge treatment are covered. Through contributions from experts in diverse fields, this book has been organised to suit a variety of readers, including professionals and students who are interested in sewage sludge treatment as well as resource recovery from sewage sludge by using different and innovative technologies.
