摘要

A great deal of progress has been made in the past decade demonstrating that household water treatment and safe storage (HWTS) improve the microbiological quality of water stored in the home and reduce the risk of diarrheal diseases in people using these technologies in developing countries. Several organizations are developing strategies to increase the impact of HWTS by scaling-up programs that promote the proven HWTS options: chlorination, solar disinfection, flocculation/chlorination, biosand filtration, and ceramic filtration (1-3). A recent review estimated that over 18 million people use HWTS, with 12.8 million using chlorination with liquid or tablet, 2.1 million using solar disinfection, 934,000 using flocculation/chlorination, 700,000 using biosand filtration, and 350,000 using ceramic filtration (4). While these numbers appear impressive, they are small compared to the estimated 1.1 billion people worldwide without access to improved water supplies.
