Access to Safe Water for the Bottom of Pyramid: Strategies for Disseminating Technology Research Benefits

This report gives background information on current applications of nanotechnology for providing clean drinking water. It includes both technologies still being developed in the laboratory and those that have reached the market.

New water filters and purification systems are now being designed with nanomaterials including carbon nanofiltration membranes, and nanocatalysts such as iron and silver. Such technologies could help countries in the developing world cope with the pressures of a growing population and stressed water services.

The review features research into water nanotechnologies from around the world, with special attention to those developed and marketed in India's water sector. It points to key challenges that may hinder their impact in providing clean drinking water to the poor, and identifies technologies that could be further researched and developed.
