Handbook For Managing Onsite And Clustered Decentralized Wastewater Treatment Systems

This book presents technical information and materials concerning the engineering of decentralized infrastructure to achieve effective wastewater treatment while also minimizing resource consumption and providing a source of reclaimed water, nutrients and organic matter. The approaches, technologies and systems described are targeted for green building and sustainable infrastructure across the United States and similar industrialized nations, but they are also applicable to water and sanitation projects in developing regions around the world. Today, decentralized infrastructure can be used to sustainably serve houses, buildings and developments with water use and wastewater flows of 100 to 100,000 gal/d or more. The book provides in-depth engineering coverage of the subject in a narrative and slide format specifically designed for classroom lectures or facilitated self-study. Key topics are covered including: engineering to satisfy project goals and requirements including sustainability, contemporary water use and wastewater generation and methods to achieve water use efficiency and source separation, alternative methods of wastewater collection and conveyance, and treatment and reuse operations including tank-based (e.g., septic tanks, aerobic treatment units, porous media biofilters, membrane bioreactors), wetland-based (e.g., free water surface and vegetated subsurface bed wetlands), and land-based unit operations (e.g., subsurface soil infiltration, shallow drip dispersal). Approaches and technologies are also presented that can achieve nutrient reduction and resource recovery in some cases or pathogen destruction to enable a particular discharge or reuse plan. The book also describes requirements and methods for effective management of the process solids, sludges and residuals that can be generated by various approaches, technologies, and systems. The book contains over 300 figures and illustrations of technologies and systems and over 150 tables of design and performance data. There are also more than 200 questions and problems relevant to the topics covered including example problems that have solutions presented to illustrate engineering concepts and calculations.

"This manual contains overview information on treatment technologies, installation practices, and past performance."--Introduction.

This book provides up-to-date information on the concepts and technologies in decentralized sanitation for wastewater treatment and management. It addresses the knowledge gap that exists between the understanding of centralized and decentralized wastewater treatment approaches. Decentralized Sanitation and Water Treatment: Concept and Technologies covers the sustainability principles and technologies involved, and common decentralized treatment and disposal methods. It includes topics like septage as a resource, resource recovery, anaerobic treatment of domestic sewage, and decentralized sanitation in various countries. Features Provides case studies from all around the world to explain the traditional and advanced technologies in decentralized sanitation and wastewater treatment Discusses real examples and cases from rural, urban, and peri-urban areas Focuses on interdisciplinary approaches of sustainability and circular economies Covers topics like water recycling, resource recovery, and use of sustainable energy sources Reviews common treatments and disposal methods of decentralized sanitation The book is meant for professionals and researchers working on wastewater treatment, environmental engineering, and ecology.

Get the single-source solutions guide to the sustainable management of water resources. Why is water the environmental issue? The answer is simple: without it, life on this planet could not exist. Yet, despite this fact, reckless consumption practices from a growing population are drying up the Earth's already limited water resources. Other factors, such as river and lake contamination, rising temperatures, and disproportionate geographic accessibility further contribute to the fresh water crisis. To confront this pressing concern, this enlightening guide, which covers over twenty case studies offering insights into real-world projects, uses a holistic, integrated approach to illustrate ways to preserve vital water supplies -- from green design remedies to encouraging greater personal responsibility. This book: Provides a basic overview of water resources, hydrology, current problems involving water resources, and the potential impact of global warming and climate change. Covers watershed planning, Best Management Practices, and potential design and planning solutions. Offers a concise overview of the issues affecting water use and management. Includes a full chapter dedicated to planning issues, and a full chapter covering site planning, design, and implementation. Sustainable Solutions for Water Resources takes a practical approach to head off a global water catastrophe by offering sensible measures that can be put in place immediately to promote a clean, plentiful flow of the Earth's most precious resource.
