| Abstract | Chlorination followed by filtration was recently reported to be one of the most efficient and economical method for iron removal compared to the other treatment methods. Based on the above findings. this study was conducted to determine the effects of both chemicals and physical parameters on the removal efficiency of the filter by this process. The study indicate about 30 percent of the stoichiometric value of the hypochlorite concentration is required for complete oxidation of ferrous to insoluble ferric state. No pH adjustment of the water is found to be necessary. It was also found that the optimum sand size for iron removal was 0.85 to 1.00 mm and the removal efficiency is dependent on the influent and effluent iron concentration and rate of filtration. SAATCI's (BDST) and MINT'S equation can be successfully used to predict to predict the efficiency of the filter performance and provides a means for rational design of filter with the help of limited number of pilot-scale experiments. |
