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.

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.

Drinking water availability and safety is a major challenge faced globally and is highly pronounced in developing countries worldwide. Lack of safe potable water across the globe can be attributed to industrial pollution, climate change and other human activities that result in a spectrum of chemical, physical and biological pollutants entering a water body. Although efforts to solve this problem are well underway worldwide, challenges still exist. This book shines a light on drinking water treatment methods and scale of operation specifically for the developing countries. Covering both conventional and emerging treatment technologies, the authors discuss the removal of chemical, physical and biological pollutants from drinking water, with a focus on developing countries. Conservation by rainwater harvesting, wastewater reuse, and selection criteria of feasible methods are considered in the context of issues relevant to Africa, Asia, Latin America and the Caribbean. With case studies connecting theory to real world matters, showcasing efficiencies and drawbacks, this book is ideal for graduate and postgraduate level course use in engineering departments or for self-study and research.

UN studies show that high-income, developed nations treat about 70 percent of their wastewater. However, in low-income developing nations, only 8 percent of wastewater undergoes any kind of treatment. Inadequate water treatment has serious consequences for both human health and the environment. The articles in this compendium provide a representative cross sample of both developing and developed nations' water treatment facilities. Included are the following topics: Reclaimed water for irrigation reuse in developing countries Sludge-handling practices in Micronesia The removal of phthalate esters from Chinese water sources Disposal of domestic wastewater in Nigeria Ameba-enrichment in a South African water treatment plant Bioenergy from wastewater produced by a Brazilian meat-processing plant The presence of various pharmaceutical contaminants in the River Thames Wastewater recycling in Greece The impact on surface water from contaminants released from German water treatment plants A Canadian constructed wetland's effectiveness for the removal of various contaminants from wastewater Accessing irrigation from treated wastewater in the United States The spacial distribution of fecal indicator bacteria in the groundwater beneath two American water treatment plants Detection of contamination from retinoid acid reception agonists in Japanese water treatment plants The editor, a respected international expert in the field, has selected investigations that offer essential information for ongoing research at the graduate and professional levels, as well as for environmental engineers and others responsible for choosing the most efficient water treatment technologies.

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

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.
