| الوصف: | In Bangladesh, many arsenic mitigations have been conducted these 25 years since the first detection of Ascontamination of groundwater in 1993. Now, according to DPHE/JICA1） report, 19 million people do not have access to any safety water options （SWOs） yet, and also 4.6 million people are still living where Ascontaminated ratio is more than 80% but safe water coverage is less than 20%. It is the worst Ascontaminated areas. The Asia Arsenic Network （AAN）2） had the chance to study the situations of Asmitigation and construct SWOs in some of these worst areas. There were many highly As-contaminated tube wells with low Fe-concentrations. AIRP/GSF, used considerably in Bangladesh, can't be applied to these highly As-contaminated tube wells because that the iron concentration in tube well water is not so high as arsenic can be removed by the iron co-precipitation. In order to supply safe water in the highly As-contaminated areas, Multi-GSF3） has been developed by adding more tanks （iron tank and gravel tank） to the traditional GSF. This paper describes the arsenic-removal performance of Multi-GSF for highly As-contaminated groundwater. ; other |
