This book was released on 2017-01-27 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Water Management is essential for the social, economic, and environmental growth of developing countries. Many of those had very high population growth rates in the last century, resulted in fast urbanization and strengthened by heavy migration from rural areas to the cities either of big or small size. Water supply of good quality and adequate quantity, especially in countries with semi-arid regions, and appropriate sewerage systems and treatment of wastewaters impaired severe constraints for the population. Nevertheless, many alternatives for wastewater treatment were developed with the participation of universities and research institutions as well as by practitioners. Substantial efforts have been directed towards the search of good alternatives for domestic sewage treatment in metropolitan regions and small cities in developing countries in order to comply with their particular economic and environmental conditions. The use of conventional treatment technologies as well as advanced alternatives for treatment and post-treatment of wastewater, issues of plant scales in centralized and decentralized systems, and possible reuse of the effluents were aimed to present on this workshop and to discuss theoretical and practical aspects. The main objectives of the workshop were (i) to share experiences, knowledge, and research between different partners; (ii) to discuss major problems and challenges in the field of wastewater treatment and reuse in Metropolitan Regions and Small Cities in Developing Countries; (iii) to present suitable treatment technologies for domestic wastewater for the removal of recalcitrant substances and micro-pollutants from domestic sewage and industrial effluents; and (iv) likeliness of reuse of treated wastewater in urban areas, in the industry, and in agriculture. Individual topics dealt with were (v) alternatives for domestic sewage treatment in metropolitan regions and small cities; (vi) anaerobic processes for the treatment of domestic sewage and industrial wastewaters; (vii) stabilization ponds; (viii) aerobic granular sludge; (ix) post-treatment processes; (x) centralized and decentralized systems; and (xi) water reuse.

Book excerpt: Small towns in low- and middle-income countries are growing rapidly and struggling to meet the increased demands of wastewater collection and treatment. To avert public health crises and continued environmental degradation, small towns are actively seeking safely managed sanitation solutions, appropriate for their scale, institutional capacity, financial resources, and overarching needs. This document is designed to provide a guide of small-town wastewater treatment processes in order to assist engineers, managers and other stakeholders responsible for wastewater service provision in identifying and selecting appropriate wastewater treatment processes for small towns. This guide is part of a World Bank suite of tools and other material to support World Bank teams and their government counterparts in the planning, design, and implementation of sanitation projects in urbanizing areas. Addressing the specific context of small towns, the format of this guide begins with an introduction of key concepts for a decision maker to understand and then applies a suggested five-step approach to exploring appropriate wastewater treatment technologies, culminating with case studies from three regions applying this approach. It delves into the unique considerations for small-town wastewater treatment and the exploration of corresponding technologies. Before demonstrating the application of the approach, the guide also navigates: (a) factors external to the technologies that define the characteristics and environment of a given small town and that will affect technology choice; and (b) technology-specific information that will ultimately influence decision making. Before embarking on the formal planning and design process, the user is highly encouraged to become familiar with the guide methodology in its entirety while drawing on the principles of the Citywide Inclusive Sanitation approach.
Download or read book Sustainable Treatment and Reuse of Municipal Wastewater written by Menahem Libhaber and published by IWA Publishing. This book was released on 2012-05-31 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Domestic Wastewater Treatment in Developing Countries written by Duncan Mara and published by Routledge. This book was released on 2013-06-17 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Affordable and effective domestic wastewater treatment is a critical issue in public health and disease prevention around the world, particularly so in developing countries which often lack the financial and technical resources necessary for proper treatment facilities. This practical guide provides state-of-the-art coverage of methods for domestic wastewater treatment and provides a foundation to the practical design of wastewater treatment and re-use systems. The emphasis is on low-cost, low-energy, low-maintenance, high-performance 'natural' systems that contribute to environmental sustainability by producing effluents that can be safely and profitably used in agriculture for crop irrigation and/or in aquaculture, for fish and aquatic vegetable pond fertilization. Modern design methodologies, with worked design examples, are described for waste stabilization ponds, wastewater storage and treatment reservoirs; constructed wetlands, upflow anaerobic sludge blanket reactors, biofilters, aerated lagoons and oxidation ditches. This book is essential reading for engineers, academics and upper-level and graduate students in engineering, wastewater management and public health, and others interested in sustainable and cost-effective technologies for reducing wastewater-related diseases and environmental damage.

Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
Download or read book Municipal Wastewater Management in Developing Countries written by Zaini Ujang and published by IWA Publishing. This book was released on 2006-04-30 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Municipal Wastewater Management in Developing Countries discusses various approaches to municipal wastewater management in order to protect both public health and the environment, with the major focus being on waterborne diseases. Developing countries can be divided into two main categories, i.e. countries in transition with higher growth rates where industrialisation and urbanisation are taking place rapidly, and countries with slower growth rates. It is important, therefore, that approaches should be tailor-made and site-specific. In general, the major trends of water pollution control have significantly contributed to the development of ?conventional sanitation? approaches in terms of legal and financial frameworks, as well as technological enhancement. Despite advances in the science, engineering and legal frameworks, 95 per cent of the wastewater in the world is released into the environment without treatment. Only five per cent of global wastewater is properly treated using the ?standard? sanitation facilities, mainly in developed countries. As a result, the majority of the world?s population is still exposed to waterborne diseases, and the quality of water resources has been rapidly degraded, particularly in poor developing countries. The challenge now is to provide the world?s population, especially the poor, with adequate water and sanitation facilities. Despite billions of dollars of investment spent every year, billions of poor people are still suffering and dying because of poor sanitation. At the beginning of this century, about 1.1 billion people lived without access to clean water (compared to about the same number in 1990), 2.4 billion without appropriate sanitation (compared to 2.3 billion in 1990) and four billion without sound wastewater disposal. The future scenario, that water resources will be further depleted by a growing world population, will be coupled with environmental degradation due to poor pollution control, particularly in most of the developing countries. In order to address the issue of water and wastewater management in developing countries it is necessary to take into consideration the segments of the society itself, particularly the types of housing areas. The segments will indicate the level of socio-economic, mentality and knowledge, which is important for any planned changes in their life style and social engineering. It is also important to segregate the funding framework of any proposed projects. High-income urban communities, for instance, are generally willing to pay for sewerage services and higher water supply tariffs, therefore a designated system can be accordingly provided. Over the past 10 years, serious criticism has been given to the ?conventional sanitation? approach, consequently many definitions, concepts and characteristics have been proposed on ?sustainable sanitation?. Sustainable sanitation is a relevant concept in order to achieve the Millennium Development Goals by 2015 of providing water supply and adequate sanitation for developing countries. Sustainable sanitation is flexible in approach any community ? poor or rich, urban or rural, water-rich or water-poor country ? and requires lower investment costs compared to conventional sanitation approaches. It is also important to note that the framework of sustainable sanitation is much easier to adopt in developing countries where water supply and sanitation infrastructures are still in the developing stages. In some developing countries, no public facilities are available therefore it is an ideal condition to start a new infrastructure with a new framework. This comprehensive reference, prepared by leading international authorities, will provide an invaluable reference for all those concerned with the management of sanitation services in developing countries worldwide.

Download or read book Drivers and characteristics of wastewater agriculture in developing countries results from a global assessment written by Raschid-Sally, L., Jayakody, P. and published by IWMI. This book was released on 2009 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 4 out of 5 cities in developing countries, wastewater is used to cultivate perishable crops for urban markets. Such practices create a health risk but provide important livelihood benefits. This study through an analysis of 53 cities in developing countries, contributes to understanding the factors that drive wastewater use. The main drivers are (1) increasing urban water demand without wastewater treatment causing pollution of irrigation water sources; (2) urban food demand favoring agriculture close to cities where water sources are polluted; and (3) lack of cheaper, similarly reliable or safer water sources. Poverty, which constrains the infrastructure needs of urbanization, is an added factor. The study makes policy recommendations stressing on, effectively applying the WHO guidelines, linking investments in water supply with sanitation for maximum beneficial impact on water pollution, and involving actors at both the national and local level, for water quality improvements and health risk reduction

Book excerpt: The books provides a timely analysis in support of a paradigm shift in the field of wastewater management, from ‘treatment for disposal’ to ‘treatment for reuse’ by offering a variety of value propositions for water, nutrient and energy recovery which can support cost savings, cost recovery, and profits, in a sector that traditionally relies on public funding. The book provides new insights into the economics of wastewater use, applicable to developed and developing countries striving to transform wastewater from an unpleasant liability to a valuable asset and recasting urbanization from a daunting challenge into a resource recovery opportunity. “It requires business thinking to transform septage and sewage into valuable products. A must read for water scholars, policy makers, practitioners, and entrepreneurs". Guy Hutton, Senior Economist, Water and Sanitation Program, Water Global Practice, World Bank “This book provides compelling evidence and real solutions for the new ‘resource from waste’ approach that is transforming sanitation, boosting livelihoods, and strengthening urban resilience”. Christopher Scott, Professor and Distinguished Scholar, University of Arizona “This book shows how innovative business thinking and partnerships around resource recovery and reuse fit well within an inclusive green economy and climate change adaptation and mitigation strategies”.

Download or read book The Real Business of Ancient Maya Economies written by Marilyn A. Masson and published by University Press of Florida. This book was released on 2020-08-25 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: A timely synthesis of the latest research and perspectives on ancient Maya economics, this volume illuminates the sophistication and intricacy of economic systems in the Preclassic, Classic, and Postclassic periods. Contributors from a wide range of disciplines move beyond paradigms of elite control and centralized exchange to focus on individual agency, highlighting production and exchange that took place at all levels of society. Case studies draw on new archaeological evidence from rural households and urban marketplaces to reconstruct the trade networks for tools, ceramics, obsidian, salt, and agricultural goods throughout the empire. They also describe the ways household production integrated with community, regional, and interregional markets. Redirecting the field of ancient Maya economic studies away from simplistic characterizations of the past by fully representing the range of current views on the subject, this volume delves deeply into multiple facets of a complex, interdependent material world.
