Drawing on the authors' combined experience of more than 30 years, Advanced Onsite Wastewater Systems Technologies explores use of these technologies on a wide-scale basis to solve the problems associated with conventional septic tank and drain field systems. The authors discuss a regulatory and management infrastructure for ensuring long-term, rel
Composting toilet systems and other ecological wastewater management methods are emerging as viable and cost-saving alternatives to wastewater disposal systems worldwide. Find out why-and how to choose, install and maintain them!In this book, you'll find:ʺ Descriptions of more than 40 systems-both manufactured and site-built-and their sourcesʺ Information on compatible toilet stools and installing micro-flush toiletsʺ Tips on choosing, planning, installing and maintaining your composting toilet systemʺ The experiences of owner-operators worldwideʺ What you should know about graywater and its treatmentʺ Regulations and advice about getting your system approved. David Del Porto has sold and serviced thousands of several models and brands of composting toilet systems since 1972. He has also helped write regulations and performance standards for these systems, and has designed composting toilet and graywater systems for Greenpeace, government agencies and for developing countries. 25 years of his research and experience is detailed in the book.,D.
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.
Our book addresses the needs of practitioners, engineers, scientists, regulators, resource managers, planners, and others with a need to know about septic systems. It arose after discussions about the need for a text that integrated current understanding of the hydrologic, physical, chemical, and biological processes involved in the treatment of wastewater using soil. In our experience, people working with septic systems – ourselves included – have a fragmented understanding of what these systems are, how they function, how wastewater moves through soil, how and which pollutants are removed, and how these systems impact the environment and public health. The relevant information is scattered across disciplines, information sources and audiences. This book is an attempt to collect and integrate this information in one place, and provide a scientific framework for understanding soil-based wastewater treatment.
This book introduces the innovative and emerging microbial technologies for the treatment, recycling, and management of industrial, domestic, and municipal water and other wastewater in an environment-friendly and cost-effective manner. It discusses existing methods and technologies, up-gradation of existing technologies, and new technologies. It also highlights opportunities in the existing technologies along with industrial practices and real-life case studies.
Septic systems for handling sewage have to be maintained but little information is available on the subject. This manual explains how they work, the potential problems that owners often encounter and how to repair them when they go awry.
