Air Kelantan Sdn Bhd (AKSB) does not supply water for all areas in Kelantan and one
of the areas happens to be Kg. Budi, which is situated in Tawang, Bachok. The
communities use groundwater from their private or other initiatives but the
groundwater is contaminated with iron (Fe) and manganese (Mn). This study
discusses treatment of groundwater containing iron (Fe) and manganese (Mn) using
a replicated model of the real treatment system at Kg. Budi. Emphasis is placed on
characterizing groundwater in terms of four parameters which are iron (Fe),
manganese (Mn), total suspended solid (TSS) and turbidity and also on studying the
performance of each unit of the real treatment system (aeration, sedimentation and
filtration methods). The experiments using the replicated model were done in two
ways; with and without aeration. The filtration unit in both experiments were tested
using different sizes and bed depth of sand. Results showed that with aeration
experiment removed contaminants up to 20% higher than without aeration
experiment. Sand grain size and sand bed depth also affected physical water quality.
This proves that the treatment system is effective in removing iron (Fe) and
manganese (Mn).
