A Practical Study on the Development and Expansion of Arsenic Removal Equipment in Rural Areas of Bangladesh

在孟加拉国，很大一部分地下水含有天然砷。然而，农村人口饮用和烹饪使用地下水，这是2008年24，000至38，000例砷中毒患者的主要原因。为了缓解这种情况，砷和铁去除厂（AIRP）在本研究项目中使用当地可用的材料建造。该工厂使用砂滤器可以去除砷。AIRP由当地可用的混凝土环制成，并通过使用砂滤器过滤来去除Fs-As絮状物。对AIRP的性能进行了监测，并进行了论证性可行性研究，以评估其推广的可能性。研究了AIRP扩散的经济可行性和影响，用户支付意愿分析。并探讨了AIRP商业化的可能性。

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.
