Download and read online ebook Fundamentals of Wastewater Treatment and Engineering write by Rumana Riffat. This book was released on 2022-04-27. Fundamentals of Wastewater Treatment and Engineering available in PDF, EPUB and Kindle. The 2nd edition of Fundamentals of Wastewater Treatment and Design introduces readers to the fundamental concepts of wastewater treatment, followed by engineering design of unit processes for sustainable treatment of municipal wastewater and resource recovery. It has been completely updated with new chapters to reflect current advances in design, resource recovery practices and research. Another highlight is the addition of the last chapter, which provides a culminating design experience of both urban and rural wastewater treatment systems. Filling the need for a textbook focused on wastewater, it covers history, current practices, emerging concerns, future directions and pertinent regulations that have shaped the objectives of this important area of engineering. Basic principles of reaction kinetics, reactor design and environmental microbiology are introduced along with natural purification processes. It also details the design of unit processes for primary, secondary and advanced treatment, as well as solids processing and removal. Recovery of water, energy and nutrients are explained with the help of process concepts and design applications. This textbook is designed for undergraduate and graduate students who have some knowledge of environmental chemistry and fluid mechanics. Professionals in the wastewater industry will also find this a handy reference.

A-B processes: Towards Energy Self-sufficient Municipal Wastewater Treatment available in PDF, EPUB and Kindle. 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.

Download and read online ebook Biological Treatment Processes write by Lawrence K. Wang. This book was released on 2009-05-07. Biological Treatment Processes available in PDF, EPUB and Kindle. Pollution and its effects on the environment have emerged as critical areas of research within the past 30 years. The Handbook of Environmental Engineering is a collection of methodologies that study the effects of pollution and waste in their three basic forms: gas, solid, and liquid. In Volume 8, Biological Treatment Processes, tried-and-true solutions comprise a “methodology of pollution control”. The distinguished panel of authors contributes detailed chapters, which include topics ranging from treatment by land application, activated sludge processes, and submerged aeration to trickling filters, lagoons, rotating biological contactors, sequencing batch reactors, digestions, and composting. Volume 8 and its sister book - Volume 9: Advanced Biological Treatment Processes – are designed as both basic biological waste treatment textbooks and reference books for advanced undergraduate and graduate students – as well as for designers of waste treatment systems, scientists, and researchers. An indispensable addition to the Humana Press series, Volume 8: Biological Treatment Processes provides an illuminating look at water pollution control and the fascinating evolution of bio-environmental engineering.
