Available in PDF, EPUB and Kindle. Book excerpt: Natural disasters, such as floods, tsunamis, hurricanes, and earthquakes, affect over 226 million people every year. The occurrence of these natural disasters has been increasing every year due to the effect of extreme weather events and higher populations living in areas vulnerable to natural hazards. Developing a guideline for emergency water treatment becomes even more important as the number of natural events continues to increase. Simple and low cost technologies have been developed to provide ways to treat water, ranging from point of use (POU) treatment to small scale (SS) community treatment. During times of natural disasters, POU and SS technologies offer applicable ways for providing clean and safe water. This guide to emergency water treatment has been developed based on current research, products, and field studies to create an expeditious and easy process for choosing which technology is most appropriate in each emergency situation. Initial, rapid response for water treatment should have the following characteristics: Portable Low cost Light weight Ease to use or requiring minimal training Requiring minimal or no external power A solution for long term response should have the following characteristics: Ability to support a community or large population Able to purify large volume of water Parts that do not require frequent replacements Does not require complex training to operate Uses easily available power sources This is a valuable resource for Environmental Engineers, Civil Engineers, Environmental Engineering Technicians and Civil Engineering Technicians.

This book was released on 2007-12-13 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developed in collaboration with the Nigerian Academy of Science, this report explores the ways in which science-based private enterprises can be created and encouraged in Nigeria and other developing countries to provide products and services that government is unable to supply in a timely and sustainable manner. Focusing on three critical challenges to health and developmentâ€"safe water, electrical lighting, and malaria therapyâ€"the report identifies a sample technology to address each of these challenges with potential for commercialization in Nigeria and Africa, and uses that sample technology to identify opportunities and barriers to creating the science-based enterprises in Nigeria.
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.

Available in PDF, EPUB and Kindle. Book 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.
