In this particular location, no electricity is available and a 200 feet deep hand-pump to
withdraw groundwater is the only source of potable water for about 50 families. However, the groundwater was contaminated with high levels of arsenic and there were symptoms of arsenic related health crisis amongst villagers. One hand-pump attached SARSAC (Sustainable Arsenic Removal System in Affected Community) unit was installed and the villagers promptly adapted to its day to day operation. Figure shows the photograph of the manually operated plant and arsenic effluent history for a period of nearly two years. Approximately 50 liters of HAIX were used in the fixed-bed column. Note that arsenic in the
treated water was consistently well below 50 μg/l (i.e., then the maximum contaminant level or MCL in India) and close to 10 μg/l, the maximum permissible limit recommended by the World Health Organization (WHO).
pleasing enough for people to consume. To reach aesthetic and drinking water standards, the
iron present in the water must be removed. Iron removal to below WHO standards (0.3 mg/L
Fe) is achieved through simple aeration and sand filtration
