This study issued on effectiveness of iron removal from synthetic ground water using ungraded sand, charcoal, burnt rice husk of which their thickness is 50 cm and mixed media (contained of 10 cm of charcoal, 20 cm of burnt rice husk and 20 cm of ungraded sand respectively). The studied filtration rate are 1 and 2 gpm while iron concentration are 5, 10 and 14 mg/l. In every experiment, burnt rice husk has the highest iron removal effectiveness while mixed media, ungraded sand and charcoal are following respectively. However, for filtration time, the longest time was produced by charcoal while mixed media, ungraded sand and burnt rice husk are shorter respectively. The suitable filter media is mixed media according to its residue iron concentration in filtered water which less than 0.3 mg/l, the acceptable level of WHO's Drinking Water Standard, as well as its long filtration time.
