Abstract:

This study was conducted to investigate the effectiveness and performance of different low-cost filter media in the removal for iron from drinking water. Three water samples were collected from Tilagor area. The iron concentrations of the collected samples were 2.5 mg l-1, 3 mg l-1 and 3.86 mg l-1 respectively. The iron concentrations of the samples exceeded the Bangladesh standard in drinking water which is 0.3-1.0 mg l-1. So, the water sample was needed to be treated to lower the iron concentration to a safe level. To prepare the filter media a several numbers of low-cost materials were collected. They were Sand (0.5 to 1.0 mm) and gravel (less than 12 mm), Neem leaves ash (0.5 to 0.6 mm), Banana leaves ash (0.5 to 0.6 mm), Wood charcoal (less than 10mm) and Rice husk (0.5 to 0.6 mm). Single measurement for each of the material was obtained to measure the effectiveness of these materials for removal of iron. The efficiency of Sand and gravel, Neem leaves ash, Banana leaves ash, Wood charcoal, and Rice husk mixture were 53%, 58%, 81% and 93% respectively. A final filter column was prepared using the best combination of these media to obtain a better performance. The efficiency of recommended filter column was measured as 98% which was satisfactory indeed.
