Application of Rice Husk Charcoal Portland Cement Membrane in Peat Water Treatment
Rice husk, a surplus agricultural byproduct, was activated and mixture with Portland cement as a membrane for peat water treatment. This research was conducted to treat peat water with Portland cement rice husk membrane. The influence of cement Portland and activated rice husk mixture ratio and the particle size of activated rice husk on the percentage removal of iron and turbidity were analyzed. The concentration of iron ion was measured by Atomic Absorption Spectrophotometer while turbidity was measured by turbidity meter. The mixture ratio of activated rice husk charcoal and Portland cement were 70:30, 60:40, 50:50, 40:60, and 30:70, while the particle size of activated rice husk charcoal was 80 and 40 mesh. The result showed that the highest percentage of iron ion removal is 99.55% which is obtained at the ratio of 70:30 rice husk Portland cement mixture. The turbidity of peat water reduces 98.86% at the composition of 70:30 and 40 mesh particle size.
