Abstract

Chemical coagulants when used in water treatment led to reduction in pH level of water, large amount of sludge production and environmental pollution. Also, chemical coagulants have high cost. To reduce the excessive use of chemical coagulants and the cost of surface water treatment, Alum and Banana peel powder (BPP) combination was used in different proportions as an alternative of chemical coagulants in this research. The comparison of removal efficiencies of turbidity, iron, copper, nitrate, TDS and TSS between the Alum and BPP combination at different proportions was done to find out the best proportion for their combination. It was observed that highest iron and copper removal efficiencies of 99.38% and 99.39% respectively were obtained when Alum and BPP used at 75% and 25% proportion, respectively. Highest turbidity, nitrate, TDS and TSS removal efficiencies of 99.77%, 97.61%, 68.42% and 99.46% respectively were obtained when Alum and BPP used at 100% and 0% proportion. It was found that the cost of surface water treatment using Alum individually was 0.12 ₹/L and for combination of Alum with BPP at proportion 75% and 25%, respectively was 0.09 ₹/L. The cost of surface water treatment reduced by 25% when Alum and BPP combination was used as a coagulantat proportion of 75%:25%.
