Sustainable Wastewater Treatment Systems

Water is one of the main concerns of modern societies. Climate change will significantly complicate access to quality water for millions of people worldwide and the threat of contamination of aquatic resources by poor wastewater management is real and growing fast. Therefore, there is an urgent need to develop efficient and sustainable wastewater treatment methods. Although there are numerous water treatment methods, not all of them are equally sustainable, be it environmentally, economically or ethically. For this book, some of the latest advances in sustainable wastewater treatments were collected and 13 articles selected. The selected articles deal with aspects such as the removal of nanoparticles, the applicability of constructed wetlands, the recovery/removal of wastewater, the use of low-cost bio-sorbents, the optimization of activated sludge, the application of advanced oxidation technologies, and the modeling of reverse osmosis systems. This book will give the reader an idea of the latest trends in the sector of sustainable wastewater treatment.

In many countries, especially in developing countries, many people are lacking access to water and sanitation services and this inadequate service is the main cause of diseases in these countries. Application of appropriate wastewater treatment technologies, which are effective, low cost (in investment and especially in operation and maintenance), simple to operate, proven technologies, is a key component in any strategy aimed at increasing the coverage of wastewater treatment. Sustainable Treatment and Reuse of Municipal Wastewater presents the concepts of appropriate technology for wastewater treatment and the issues of strategy and policy for increasing wastewater treatment coverage. The book focuses on the resolution of wastewater treatment and disposal problems in developing countries, however the concepts presented are valid and applicable anywhere and plants based on combined unit processes of appropriate technology can also be used in developed countries and provide to them the benefits described. Sustainable Treatment and Reuse of Municipal Wastewater presents the basic engineering design procedures to obtain high quality effluents by treatment plants based on simple, low cost and easy to operate processes. The main message of the book is the idea of the ability to combine unit processes to create a treatment plant based on a series of appropriate technology processes which jointly can generate any required effluent quality. A plant based on a combination of appropriate technology unit processes is still easy to operate and is usually of lower costs than conventional processes in terms of investment and certainly in operation and maintenance. Chapters in the book are organized in a practical and accessible way to: Demonstrate selected unit process of appropriate technology and provide the scientific basis, the equations and the parameters required to design the unit processes, with some innovations developed by the authors. Highlight design procedures for selected combined processes which are in use in developing countries. Propose an innovative Orderly Design Method (ODM), which is easy to follow by practicing engineers, using the equations and formulas developed, once the fundamentals of each unit and combined process have been established. Provide a numeric example for the basic design of each selected appropriate technology process for a city with a population of 20,000 using the ODM and an Excel program which will be provided to the readers for download from an online web page. This book is a valuable and practical resource for all wastewater treatment engineers in field and the operational managers of waste treatment facilities. Authors: Menahem Libhaber, PhD, Consulting Engineer to the World Bank and other institutions, Alvaro Orozco Jaramillo, MSc, Consulting Engineer to the World Bank, the Inter-American Development Bank, Biwater and other institutions in various countries.

Wastewater management in developing countries throughout the world is in a state of crisis. It is estimated that 2.6 billion people worldwide live without adequate sanitation. Resources are scarce, previous management systems have failed, and traditional techniques and solutions are not immediate enough, too expensive, or simply inefficient. This book investigates the complex political, economic, and cultural reasons that so many developing nations lack the ability to provide proper and effective wastewater treatment for their citizens. The authors draw upon their experiences in Malaysia, Thailand, and other countries to inspire innovation and improvement in wastewater treatment and management. They examine the failures of traditional planning, design, and implementation, and offer localized solutions that will yield effective sustainable management systems. These solutions include reuse of treated wastewater, energy conservation, and proper financial and organizational set up. Sustainable Wastewater Management in Developing Countries will urge practitioners, decision makers, and researchers to approach these systems in new ways that are practical, innovative, and?best of all?sustainable.

This book deals with natural treatment systems and the challenges the water industry faces in dealing with sustainability and the realisation of reaching Net Zero by 2030.Surface waters are all under threat, with freshwater ecosystems now facing unprecedented levels of contamination, even after a century of ever stricter legislation and regulation. The increase in population and especially in urbanization without sufficient planning and investment to ensure adequate wastewater collection and treatment coupled with the need to reduce greenhouse gas emissions associated with wastewater treatment is leading to a crisis in wastewater treatment in many countries.Natural treatment systems which use plants and soil micro-organisms are very much nature-based solutions and wherever applicable might offer sustainable and low emissions options for a range of wastewater problems protecting surface waters as well as creating new habitats to support and enhance wildlife diversity. In terms of circularity, natural treatment systems have the potential to produce a staggering array of useful and valuable by-products, including high-value compounds for the pharmaceutical industry.Related Link(s)

Ensuring safe and plentiful supplies of potable water (both now and for future generations) and developing sustainable treatment processes for wastewater are among the world’s greatest engineering challenges. However, sustainability requires investment of money, time and knowledge. Some parts of the world are already working towards this goal but many nations have neither the political will nor the resources to tackle even basic provision and sanitation. Combining theory and practice from the developing and developed worlds with high- and low-tech, high- and low-cost solutions, this book discusses fundamental and advanced aspects of water engineering and includes: water resource issues including climate change, water scarcity, economic and financial aspects requirements for sustainable water systems fundamentals of treatment and process design industrial water use and wastewater treatment sustainable effluent disposal sustainable construction principles With integrated theory, design and operation specifications for each treatment process, this book addresses the extent to which various treatment methods work in theory as well as how cost effective they are in practice. It provides a nontechnical guide on how to recover and reuse water from effluent, which is suitable for those in water resource management, environmental planning, civil and chemical engineering.
