Abstract

The main focus of this study was to remove Arsenic (As) content from groundwater using Sand Filtration Technique. Two
treatments, that is, T1 (Charcoal) and T2 (Iron nails) were used to study the removal efficiency of As from groundwater by
column experiments at room temperature (20–25°C) for 30 days. Column experiments were conducted to examine the removal
efficiency of As in charcoal and iron nails filters. The study of adsorption involved in removal of As concentrations by adsorbent
materials. The charcoal sand filter showed the maximum removal efficiency As is 96% and adsorbed As concentration is 1.92 mg
and the presence of iron nails in sand filter showed that the removal efficiency of As is 85% in 30 days. The sand filter embedded
with charcoal was the most constant and effective than the filter embedded with iron nails under the similar conditions. This
features the positive effect on As removal in charcoal sand filter than the iron nails. The sand filters serve as good option for the
treatment of groundwater contained As, recommended for the developing countries.
