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.

The need for fresh water is increasing with the rapid growth of the world's population. In countries and regions with available water resources, it is necessary to ensure the health and safety of the water supply. However, in countries and regions with limited freshwater resources, priority is given to water supply plans and projects, among which the desalination strategy stands out. In the desalination process, membrane and thermal processes are used to obtain fresh water from salty water that is in abundant amounts in the sea. This book will outline valuable scientific contributions to the new desalination and water treatment technologies to obtain high quality water with low negative environmental impacts and cost. The editors would like to record their sincere thanks to the authors for their contributions.

There’s never been a better time to “be prepared.” Matthew Stein’s comprehensive primer on sustainable living skills—from food and water to shelter and energy to first-aid and crisis-management skills—prepares you to embark on the path toward sustainability. But unlike any other book, Stein not only shows you how to live “green” in seemingly stable times, but to live in the face of potential disasters, lasting days or years, coming in the form of social upheaval, economic meltdown, or environmental catastrophe. When Technology Fails covers the gamut. You’ll learn how to start a fire and keep warm if you’ve been left temporarily homeless, as well as the basics of installing a renewable energy system for your home or business. You’ll learn how to find and sterilize water in the face of utility failure, as well as practical information for dealing with water-quality issues even when the public tap water is still flowing. You’ll learn alternative techniques for healing equally suited to an era of profit-driven malpractice as to situations of social calamity. Each chapter (a survey of the risks to the status quo; supplies and preparation for short- and long-term emergencies; emergency measures for survival; water; food; shelter; clothing; first aid, low-tech medicine, and healing; energy, heat, and power; metalworking; utensils and storage; low-tech chemistry; and engineering, machines, and materials) offers the same approach, describing skills for self-reliance in good times and bad. Fully revised and expanded—the first edition was written pre-9/11 and pre-Katrina, when few Americans took the risk of social disruption seriously—When Technology Fails ends on a positive, proactive note with a new chapter on "Making the Shift to Sustainability," which offers practical suggestions for changing our world on personal, community and global levels.

Labeled either as the "next industrial revolution" or as just "hype," nanoscience and nanotechnologies are controversial, touted by some as the likely engines of spectacular transformation of human societies and even human bodies, and by others as conceptually flawed. These challenges make an encyclopedia of nanoscience and society an absolute necessity. Providing a guide to what these understandings and challenges are about, the Encyclopedia of Nanoscience and Society offers accessible descriptions of some of the key technical achievements of nanoscience along with its history and prospects. Rather than a technical primer, this encyclopedia instead focuses on the efforts of governments around the world to fund nanoscience research and to tap its potential for economic development as well as to assess how best to regulate a new technology for the environmental, occupational, and consumer health and safety issues related to the field. Contributions examine and analyze the cultural significance of nanoscience and nanotechnologies and describe some of the organizations, and their products, that promise to make nanotechnologies a critical part of the global economy. Written by noted scholars and practitioners from around the globe, these two volumes offer nearly 500 entries describing the societal aspects of nanoscience and nanotechnology. Key Themes - Art, Design, and Materials - Bionanotechnology Centers - Context - Economics and Business - Engagement and the Public - Environment and Risk - Ethics and Values - Geographies and Distribution - History and Philosophy - Integration and Interdisciplinarity - Nanotechnology Companies - Nanotechnology Organizations

Microbiology of Drinking Water Production andDistribution addresses the public health aspects of drinkingwater treatment and distribution. It explains the different watertreatment processes, such as pretreatment, coagulation,flocculation, sedimentation, filtration, disinfection, and theirimpacts on waterborne microbial pathogens and parasites. Drinking water quality may be degraded in water distributionsystems—microorganisms form biofilms within distributionsystems that allow them to flourish. Various methodologies havebeen proposed to assess the bacterial growth potential in waterdistribution systems. Microbiology of Drinking Water Production and Distributionalso places drinking water quality and public health issues incontext; it addresses the effect of bioterrorism on drinking watersafety, particularly safeguards that are in place to protectconsumers against the microbial agents involved. In addition, thetext delves into research on drinking water quality in developingcountries and the low-cost treatment technologies that could savelives. The text also examines the microbiological water quality ofbottled water, often misunderstood by the public at large.
