Available in PDF, EPUB and Kindle. Book excerpt: The continued lack of access to adequate amounts of safe drinking water is one of the primary causes of infant morbidity and mortality worldwide and a serious situation which governments, international agencies and private organizations are striving to alleviate. Barriers to providing safe drinking water for rural areas and small communities that must be overcome include the financing and stability of small systems, their operation, and appropriate, cost-effective technologies to treat and deliver water to consumers. While we know how to technically produce safe drinking water, we are not always able to achieve sustainable safe water supplies for small systems in developed and developing countries. Everyone wants to move rapidly to reach the goal of universal safe drinking water, because safe water is the most fundamental essential element for personal and social health and welfare. Without safe water and a safe environment, sustained personal economic and cultural development is impossible. Often small rural systems are the last in the opportunity line. Safe Drinking Water in Small Systems describes feasible technologies, operating procedures, management, and financing opportunities to alleviate problems faced by small water systems in both developed and developing countries. In addition to widely used traditional technologies this reference presents emerging technologies and non-traditional approaches to water treatment, management, sources of energy, and the delivery of safe water.

Available in PDF, EPUB and Kindle. Book excerpt: Safe drinking water remains inaccessible to many humans in the developing countries. Research continuously innovates to develop efficient and cheap methods to sustain clean water for developing countries. Developing nations are a broad term that includes countries that are less industrialised and have lower per capita income levels than developed countries. This chapter will discuss clean water for drinking water purposes. Pollution concerns of water in developing countries will be categorised in terms of physical, chemical and biological pollutants such as turbidity, organic matter and bacteria. Natural and anthropogenic pollution concerns linking with seasonal factors will be outlined. The multi-barrier approach to drinking water treatment will be discussed. Abstraction points used will be researched. Water treatment systems, medium- to small-scale approaches, will be discussed. The processes involved in removing the contaminants including physical processes such as sedimentation, filtration such as slow-sand filtration, coagulation and flocculation, and disinfectant processes such as chlorination will be reviewed. Other important methods including solar disinfection, hybrid filtration methods and arsenic removal technologies using innovative solid phase materials will be included in this chapter. Rainwater harvesting technologies are reviewed. Safe storage options for treated water are outlined. Challenges of water treatment in rural and urban areas will be outlined.
Download or read book Interface Science in Drinking Water Treatment written by Gayle Newcombe and published by Academic Press. This book was released on 2006-09-06 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to imagine anything more important to the human population than safe drinking water. Lack of clean drinking water is still the major cause of illness and death in young children in developing countries. In more fortunate communities, where water treatment is practiced, the primary aim of water authorities is to provide water that is free from pathogens and toxins. Most countries now have water quality regulations, or guidelines, which are driving water authorities to produce purer water, with the minimum of contamination from natural or man-made origin. At the same time, consumers are demanding that chemicals added during the treatment of drinking water be kept to a minimum. As a consequence, conventional clarification methods are being challenged to comply with the new regulations and restrictions and our understanding of the mechanisms involved is being tested as never before. Interface Science in Drinking Water Treatment contains a rigorous review of water treatment practices from a fundamental viewpoint. The book includes material from leading experts in the field of water treatment, reviewing their specific fields of expertise against a background of colloid and surface chemistry, and examines each step of the journey from source to consumer tap. It therefore permits the reader to develop a deep understanding of the complex processes taking place and of the necessary treatments which are vital for the provision of safe and palatable drinking water. The book is aimed at researchers, educators and practitioners in science and engineering, particularly those involved in water treatment and colloidal chemistry. Covers all existing water treatment processes, approached from a fundamental surface and colloid science viewpoint Unique collection of R&D authors, all experts in water treatment processes Comprehensive review of water treatment with a complete list of references

This book was released on 2018-10-23 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Waterbackpack PAUL -Portable Aqua Unit for Life Saving- is a water treatment unit based on the Ultra-Low Pressure Ultrafiltration (ULP-UF) technology and is since 2010 successfully applied as a fast response to get safe water during natural disasters or emergencies in more than 2 000 cases worldwide. In addition, PAUL has demonstrated that the ULP-UF technology can be used in permanent decentralised drinking-water supply for remote and rural areas, as it is easy to handle and does require neither chemicals nor energy consumption nor spare parts on a regular basis. Hence, the ULP-UF is an appropriate solution in the process of reaching the Sustainable Development Goals (SDGs), ensure by 2030 access to safe drinking water worldwide. However, during long-term uses and under certain water characteristics, the ULP-UF faces some operational and maintenance challenges. The biofouling adhered to the membrane surface may lead to severe flux reduction. In addition, some re-growth of bacteria may take place on the permeate side because of the presence of high content of natural organic matter (NOM) in the raw water, especially Biopolymer and Humic Acids. Therefore, the aim of this study was to integrate some appropriate treatment steps before the ULP-UF technology, so that a reduction of attachment of NOM and biofilm to the membrane could be achieved and thus an increase of permeate flux and a reduction of potential regrowth of bacteria on permeate water could be accomplished.
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 Development of a Decentralized Drinking Water Treatment Plant Based on Membrane Technology for Rural Areas in Vietnam written by Ngoc Dao Trinh and published by kassel university press GmbH. This book was released on 2018-06-28 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane technology with effective removal of microbial contaminants has been applied widely in drinking water treatment (DWT), but its sustainable and efficient application in rural areas still needs practical research. Backflushing and chemical cleaning are well investigated for membrane-based systems. However, these methods are not always followed properly and in full, especially in cases of applications for remote areas in developing countries. Important key challenges in real world applications are how the system would actually sustain with unskilled personnel, with no electric power for backflushing or with no chemical cleaning on the long run. These challenges were addressed within the framework of this dissertation. A dead-end Ultrafiltration (UF) with flat-sheet membranes was configured to a stationary DWT system working with low pressure and simplest maintenance, in combination with a suitable chlorination solution without energy demand. In the literature review of this dissertation, an overview of many up-to-date membrane based systems in different categories of use is given in detail, covering different aspects of technology, service efficiency and economics. Hydraulic performance of membrane-based systems is normally studied in lab-scale in limited periods from hours to days. Thus, highlight of this research is the investigation of a full-scale demonstration plant based on UF flat-sheet membrane with pore size of 40 nm, conducted in the Hydraulic Workshop at the University of Kassel, operated continuously day and night for long-term tests. The long-term examination focused on many aspects, from hydraulic performance including flux, permeability, transmembrane pressure, efficiency of the simple membrane cleaning methods, to biological quality of treated water and also efficiency of chlorination by using a mechanical chlorine dosing device. During long-term examination, the phenomenon of gas generation from the water in the plant was recognized. The influence of this phenomenon on the permeate flow rate was evaluated and solution for this problem by the gas trapping device was investigated in this research. The experimental results from long-term examination of the Pilot Plant at the University of Kassel served for the materialization of the system into life. Two DWT plants were implemented in a rural village in southern Vietnam. It could be proved that the product of this research is realistically an economic relief of the long lasted insufficient supply to the crucial demand for safe water in the rural communities of developing countries.
