Abstract

Peat water is surface water that has high color intensity, low pH (pH 3-5) and contains the high organic substance, so it has influenced the health if it's used. Purpose of this research was conducted to the removal of organic substance (%R) in peat water using in UV-Peroxidation process as discoloration signatures indication. UV-Peroxidation is one of AOP (Advanced Oxidation Processes) base on the reactiveness radical hydroxyl (HO●) that originated from the existence of H2O2 with UV radiation. The research doing by varying the concentration of H2O2 0,0 – 0,11% in the wavelength of UV lamp 360 – 240 nm for 0-240 minutes. The result of that condition was shown that the higher concentration of H2O2 and longer of radiation time led to the bigger efficiency of the removal organic substance (%R). From the experiment, it can be concluded that the optimum dose of H2O2 was gained in at 0,07% and the removal of organic concentration found to 98,56% within 240 minutes. The measurement of water discoloration indicated up to 5TCU clarity.
