A Critical Review of Water Purification Technology Appropriate for Developing Countries
Desalination and Water Treatment 54 (2015) 3487–3493 www.deswater.com June doi: 10.1080/19443994.2014.922309 A critical review of water purification technology appropriate for developing countries: Northern Ghana as a case study Michelle Thompson Institute of the Environment and Sustainability, University of California, 300 La Kretz Hall, Suite 300, Box 951496, Los Angeles, CA 90095, USA, email: [email protected] Received 15 January 2014; Accepted 14 March 2014 ABSTRACT A wide range of technologies are commercially available for water purification. However, not all of these technologies are suitable for use in rural, underdeveloped regions. Here, I present a systematic method for selecting the most appropriate technology for a particular community, using rural Ghana as a case study. In Ghana, over half of the population lives in rural areas, and two-thirds of these residents lack access to safe drinking water. Ghana has made significant strides using innovative water treatment techniques; however, there are still many hurdles. Simple and inexpensive, on-site water filtration technologies are a promising method for removing protozoans and other micro-organisms that pose significant health risks in underdeveloped, rural areas. In this review, several of these commercially available on-site water filtration technologies are assessed based on the following factors: effectiveness, cost, energy consumption, environmental impacts, and waste generated. This ® analysis suggests that for rural communities in Ghana, LifeStraw and ceramic clay pots are the most appropriate technologies. Implementation of these technologies poses potential benefits in terms of cost effectiveness and economic growth. Although this paper focuses on northern Ghana as a case study, the methodology presented here can be readily extended to specific scenarios in other developing countries. -

Nanotechnology for a Safe and Sustainable Water Supply: Enabling Integrated Water Treatment and Reuse XIAOLEI QU, JONATHON BRAME, QILIN LI,* AND PEDRO J. J. ALVAREZ* Department of Civil and Environmental Engineering, Rice University, Houston, Texas 77005, United States RECEIVED ON JANUARY 28, 2012 CONSPECTUS nsuring reliable access to clean and affordable E water is one of the greatest global challenges of this century. As the world's population increases, water pollution becomes more complex and difficult to remove, and global climate change threatens to exacerbate water scarcity in many areas, the magni- tude of this challenge is rapidly increasing. Waste- water reuse is becoming a common necessity, even as a source of potable water, but our separate waste- water collection and water supply systems are not designed to accommodate this pressing need. Furthermore, the aging centralized water and wastewater infrastructure in the developed world faces growing demands to produce higher quality water using less energy and with lower treatment costs. In addition, it is impractical to establish such massive systems in developing regions that currently lack water and wastewater infrastructure. These challenges underscore the need for technological innovation to transform the way we treat, distribute, use, and reuse water toward a distributed, differential water treatment and reuse paradigm (i.e., treat water and wastewater locally only to the required level dictated by the intended use). Nanotechnology offers opportunities to develop next-generation water supply systems. This Account reviews promising nanotechnology-enabled water treatment processes and provides a broad view on how they could transform our water supply and wastewater treatment systems. -
Batch Water Purification: an Option for Small Scale Users
batch plants ;-\i:; COMMUNITY WATER SUFPi.Y. Batch water purification: An option for small scale users By Mr A Botha. B Eng (Hons) (Chem) Pretoria University; Division of Water Technology. CSIR. Providing adequate drinking water of acceptable quality to small communities is a complex problem. A water purification system is 2 5 described in terms of chemical engineering principles. The flocculation system and specifically the equivalent plug flow reactor is then 8 9 B A evaluated to determine the stability of the system. This analysis indicated that this system is complex and may only be controllable in large purification plants. An analysis of a batch reactor indicated that this type of flocculation system results in a more stable and appropriate system for small scale water purification plants. The control, operation and optimisation of water purification • Plug flow reactor processes is complex and requires skilled operators. Small This type of reactor usually takes the form of a tube into which communities seldom have access to. or are able to afford, reactants are pumped from one end and the product removed such skilled personnel. This leads to problems regarding the from ihe other. Plug fiow is a simplified picture of the motion quality of water supplied by small water purification systems. of a fluid, where all the fluid elements move with a uniform The objective of this discussion is to describe water velocity along parallel streamlines, with no back-mixing. All purification in terms of chemical engineering principles and to chemical and thermal changes may therefore be related to a derive a simple solution to enhance the ability of small length unit, parallel to the fluid flow direction. -
