| Research Abstract |
In Bangladesh, significant part of groundwater contains nature-derived arsenic. However, rural people are using ground water for drinking and cooking, which accounts for large number of arsenicosis patients of 24,000 to 38,000 in 2008. To mitigate this situation, an Arsenic and Iron Removal Plant (AIRP) was constructed in this research project using locally available materials. The plant uses a sand filter that can remove the arsenic. The AIRP is made with locally available concrete ring and removes Fs-As flock by filtration using sand filter. The performance of the AIRP was monitored and demonstrative feasibility study was carried to evaluate possibility of its diffusion. Economical feasibility and impact of AIRP diffusion, analysis of willingness to pay of users were studied. Possibility of commercialization of AIRP was also studied.
