Technologies for safe water supply in arsenic affected villages of Bangladesh utilizing a pedal pump
MetadataShow full item record
This paper presents information on the socio-techno-economic aspects of a water purification system for the arsenic contaminated villages of Bangladesh. The proposed system which is based on hollow fiber membranes and granular activated carbon columns can be used to harvest potable water from ponds without many of the problems inherent in the conventional pond sand filters. This paper also examines the possible application of human operated pedal pump, instead of diesel or electricity driven pump, for pumping water from ponds to overcome limitations in existing water technologies in the arsenic-contaminated villages in Bangladesh. A market model of this technology has been suggested that allows the rural poor to access to safe water at affordable monthly rate.
