Peat water treatment using oxidation and physical filtration system and its performance in reducing iron (Fe), turbidity, and color

Abstract

This research was conducted to treat peat water using oxidation and physical filtration system. Initially, the characterization of peat water was determined by three parameters, including iron (Fe), turbidity, and color. These three parameters exhibited values that exceeded the water standard limit. This study used two samples consisting of high and low iron content. Both samples were treated using NaClO for the oxidation-catalytic process and Manganese sand for the filter. The trial time is 67 minutes by calculating the value of each parameter every 10 minutes. The result shows different performance in the sample with low iron and high iron. In the sample with low iron (0.32 mg/l), the efficiency of reducing iron is 65.62%, the efficiency of reducing turbidity is 78.95% and the efficiency of reducing color is 78.77%. The results obtained showed differences in samples with high iron (6.75 mg / l). Iron reduction efficiency is 29.17%, turbidity reduction efficiency is 69.05% and color reduction efficiency is 61.32%.
