Newcastle University
Newcastle University engineers developed a simple water filter. The unit designed by Dr
Paul Sallis and others can be made from local materials. The design is based on a mixture of
clay and crop residues - such as rice husks or bran – to produce a ceramic filter. Work was
done at the International Centre for Diarrhoeal Disease Research in Bangladesh, training
village potters to make the filters.
University of Delaware
Researchers have developed an inexpensive, nonchlorine-based technology that can remove
harmful microorganisms, including viruses, from drinking water. Developed jointly by
researchers in the College of Agriculture and Natural Resources and the College of
Engineering, It incorporates highly reactive iron in the filtering process. Currently, the Centre

Arsenic
"Remediation-in-a-bucket" technique for As-contaminated drinking water in poor
communities"
The two components are a water purifier called Slingshot that uses a fraction of the power of
alternatives and a Stirling engine based power generator that works on cow dung. The $1500
water purifier will produce 1000 liters of water a day, while the generator produces around 1
kW, which is enough to deliver light to a small village.
