Development of a Decentralized Drinking Water Treatment Plant Based on Membrane Technology for Rural Areas in Vietnam 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 influ

Desalination and Water Treatment Excerpt :

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.

Rethinking Faecal Sludge Management in Emergency Settings Excerpt :

The development of technology in the emergency sanitation sector has not been emphasised sufficiently considering that the management of human excreta is a basic requirement for every person. The lack of technology tailored to emergency situations complicates efforts to cater for sanitation needs in challenging humanitarian crisis. Concerns persists on the lack of faecal sludge management that considers the whole sanitation chain from containment until treatment. This study focused on the development of a smart emergency toilet termed the eSOS (emergency sanitation operation system) smart toilet to address the limitation in technical options. This toilet is based on the eSOS concept that takes into account the entire sanitation chain. This study also addresses the limited time for planning in emergencies by developing a decision support system (DSS) to help quick selection of optimal sanitation options. The aim was to enable users of the DSS to plan their emergency sanitation response within the shortest time possible. The study aims to contribute toward a better emergency sanitation response by application of technology advances.

Drinking Water Disinfection Techniques Excerpt :

Water is our natural heritage, our miracle of life. However, our increasingly technological society has become indifferent to water. Far from being pure, modern drinking water around the world contains many undesirable chemical and bacterial contaminants. The existing techniques employed for the disinfection of water are either energy-intensive or have by-products harmful to human health. Drinking Water Disinfection Techniques reviews these processes and explores novel technologies for water disinfection synergistic with existing techniques. The book covers a wide audience and gives a comprehensive review of various physical, chemical, and hybrid techniques commonly used for the disinfection of water as well as newer emerging technologies in terms of their mode of action, scale of operation, efficacy, merits, and demerits. It broadly addresses the issues related to water disinfection in three sections: Disinfection techniques—chemical, physical, and hybrid (combination)—and their likely scale of operation efficacy Disinfection by-product as a function of water source and the type of treatment Emerging and novel techniques, including new work on cavitation, an economical, energy-efficient, and simple alternative to the conventional methods of disinfection Drinking Water Disinfection Techniques effectively combines the chemical, physical, biological, and engineering principles of water disinfection in one text. Discussing both conventional and novel techniques used for disinfection and the economics involved, the book gives a comprehensive review of various physical, chemical, and hybrid techniques used for disinfection to create potable water.

Current Microbiological Research in Africa Excerpt :

Scientific output in low- and middle-income countries is greatly challenged by numerous factors. This is particularly pronounced in sub-Saharan African countries, despite the continent being the world’s second largest and second most-populous continent, currently undergoing rapid economic growth. Financial constraints and unclear areas of focus when funding is available, are among the limiting factors, with the consequence being the development of inadequate policies, especially those relating to environmental protection and conservation. This 13-chapter book is a unique piece in the field of microbiology, designed to stimulate some research areas in Africa by illustrating interesting and informative examples of the current applied research agenda in environmental microbiology in selected countries within the continent. With authors from the North, South, East and West of Africa, the book touches diverse applied methods and approaches to meet the pragmatic needs faced by environmental microbiologists in Africa. Also included are topics on viruses, bacteria (including cyanobacteria), and protozoa, and their importance in disease. Sustainable agriculture and aquaculture, and eco-friendly oil and hydrocarbon bioremediation and degradation approaches are highlighted. Microbial involvement in different common indoor (e.g., household kitchens, latrines, and hospitals) and outdoor settings including air, soil, and water habitats, and their resistance to commonly used antibiotics, are described. Hopefully, the work presented here will stimulate the need for increasing modern training and funding initiatives to prepare African microbiologists to meet the challenges they face in African universities and research laboratories.
