This book presents recent developments in advanced biological treatment technologies that are attracting increasing attention or that have a high potential for large-scale application in the near future. It also explores the fundamental principles as well as the applicability of the engineered bioreactors in detail. It describes two of the emerging technologies: membrane bioreactors (MBR) and moving bed biofilm reactors (MBBR), both of which are finding increasing application worldwide thanks to their compactness and high efficiency. It also includes a chapter dedicated to aerobic granular sludge (AGS) technology, and discusses the main features and applications of this promising process, which can simultaneously remove organic matter, nitrogen and phosphorus and is considered a breakthrough in biological wastewater treatment. Given the importance of removing nitrogen compounds from wastewater, the latest advances in this area, including new processes for nitrogen removal (e.g. Anammox), are also reviewed. Developments in molecular biology techniques over the last twenty years provide insights into the complex microbial diversity found in biological treatment systems. The final chapter discusses these techniques in detail and presents the state-of-the-art in this field and the opportunities these techniques offer to improve process performance.

Environmental Sustainability and Industries identifies and discusses critical areas related to environmentally conscious industrial development of products and services that may support more sustainable and equitable societies. This book addresses pollution prevention by referring to the use of processes, practices, and materials that reduce or eliminate the generation of pollutants at the source of production, more efficient use of raw materials, energy, water or other resources, or by conserving natural resources by maintaining clean production. It explains industrial energy efficiency as the most cost-effective use of energy in manufacturing processes, reducing its wastage as well as the total consumption of primary energy resources. Life cycle assessment is used as an analytical method to quantify environmental impacts, focusing on environmental considerations concerning process design and optimization, and including various sustainable manufacturing parameters in the context of industrial processes and proposes a classification of identified parameters to evaluate and optimize the manufacturing performances. The book also dives into industrial ecology, investigating how, where, and why environmental improvements can be made to develop a sustainable industry, meeting the needs of current generations without sacrificing the needs of the future ones. This book analyzes a company's environmental, social, and economic performance and their interrelationships, emphasizing the importance of identifying and understanding causal relationships between alternative approaches to action and their impact on financial and nonfinancial performance. It concludes with a view on the future of sustainable industrial systems stressing change as a joint effort of scientists, governments, people in business, and academicians.

Water Conservation and Wastewater Treatment in BRICS Nations: Technologies, Challenges, Strategies, and Policies addresses issues of water resources-including combined sewer system overflows-assessing effects on water quality standards and protecting surface and sub-surface potable water from the intrusion of saline water due to sea level rise. The book's chapters incorporate both policies and practical aspects and serve as baseline information for future adaption plans in BRICS nations. Users will find detailed important information that is ideal for policymakers, water management specialists, BRICS nation undergraduate or university students, teachers and researchers.
