This paper evaluates the Fenton process, involving oxidation and settling after coagulation and flocculation for the removal of organic, iron, color and turbidity from peat water. The experiment is to examine the operation condition which can result in the highest removal efficiency. The experimental variables studied include oxidation time, molar ratio of [H2O2]/[Fe2+], coagulation and flocculation pHs and settling time. The highest removal efficiency is resulted from operation condition of 60 minute oxidation and the coagulation pH of 8. The organic removal efficiency is around 33.40% to 46.86% for oxidation and 53% to 79.66% for settling. The highest removal of 37.92 mg/L organic is resulted from the [H2O2]/[Fe2+] molar ratio of 4.5. For organic concentration of 26.65 mg/L, the highest removal is resulted from the [H2O2]/[Fe2+] molar ratio of 3.5. The removal efficiency of iron, color and turbidity by settling process is 99% for all of the [H2O2]/[Fe2+] molar ratio. In oxidation process, the removal efficiency of iron, color and turbidity are 2% to 4%, 20% to 57%, and 17% to 42% respectively. The experiment results also show that the maximum effect of removing pollutant is occurring on settling process after coagulation and flocculation.
