Nanotechnology has introduced a new generation of water filters and
purification systems. Research on Carbon nanofiltration membranes and
nano catalysts like iron, silver and titanium dioxide for water
treatment applications is a fast growing field. Universities like
Stanford, Aberdeen, Rice, etc. as well as their Indian counterparts like
the Indian Institutes of Technology, Benares Hindu University, Indian
Institute of Science etc. are actively involved in nanotechnology
research focused on the water technology. Some technologies have
recently also been introduced in the market by companies like Eureka
Forbes Limited, TATA Chemicals, etc. for point of use application.
This report is a secondary review of available technologies in the
laboratory and the market. It is structured in three chapters. Chapter 1
offers a background to the study, focusing on current water issues
globally and nationally. It also throws light on the reasons and
approach for this study. Chapter 2 presents an overview on
Nanotechnology, especially the role of nanotechnologies in the water
sector. Prominent research from around the world is featured in the
chapter. Specifically for India, it draws attention to research agencies
that have initiated nano research. Also highlighted are nanotechnologies
marketed in India in the water purification sector. The overview sheds
light on the present market scene for nanotechnology. Policy issues and
health and environmental impacts of nanotechnologies in the water
sector, though little understood as of date, are mentioned. This is an
area that requires further work. Chapter 3 presents the way forward in
the research study. This report is derived from scanning and mapping of
the current scenario. Further the study involves consultations and
primary surveys to identify potential technologies and partners. The aim
of this report is to develop and provide a basic understanding of the
current research and market scenario with respect to nanotechnologies in
the water sector.
