Sustainable application of iron hybrid filter for arsenic removal

开发了适用于孟加拉国农村地区的除砷过滤器，那里的饮用水受到砷的高度污染。通过室内实验研究了除砷效果、干扰物质对除砷效果的影响以及除砷的预测模型。该过滤器在孟加拉农村地区应用，运行一年来不断发现除砷效果。对于含磷量较高的地下水，双重过滤似乎是有效的。这种过滤器价格低廉，可以在孟加拉国现场制造。在库尔纳市郊区举办了一家制造过滤器的车间。

Arsenic removal filter was developed that was applicable to rural areas in Bangladesh where potable ground water was highly contaminated by arsenic. Arsenic removal performance, influence of interfering materials and prediction model for arsenic removal were investigated in laboratory experiments. The filter was applied in rural area in Bangladesh and the arsenic removal performance was continuously found during one year operation. Double filtration seemed to be effective for ground water containing high phosphorous concentration. The filter was inexpensive and able to be manufactured in on site in Bangladesh. A work shop for manufacturing the filter was held in the suburban area of Khulna City.
