Abstract
PEAT WATER TREATMENT BY ELECTROCOAGULATION USING ALUMINUM ELECTRODES ( Pranawati Amalia, 2014, 51 Pages, 15 Tables, 22 Pictures, 3 Appendixs ) Peat water is surface water that flooded on area, the area where the presence of piles formed from organic material in a long time. The characteristics of the peat water is having a low pH (3-4) that is highly acid, having a high organic content, having high levels of iron and manganese, and having yellow or dark brown colour (concentrated). One of the peat area in the Kota Terpadu Mandiri (KTM), Ogan Ilir, South Sumatra. The amount of Fe and Mn in peat water is high, that’s why the treatment of peat water to lower concentration of Fe and Mn. The treatment uses electrocoagulation is performed in batch with electrode dimensions 18cm x 6.5cm x 0.2cm and the distance between the electrodes 1cm. The aluminum electrodes are contacted with peat water with varation the current density of 20 A/m2, 40 A/m2, 60 A/m2 and 80 A/m2 and varation the processing time is 30 minutes, 60 minutes, 90 minutes and 120 minutes. The result showed that the optimum pH rise occurs at 40 A/m2 current density with a time of 30 minutes is 7,87 and decrease the effectiveness of each parameter occurs at 20 A/m2 current density with processing time of 120 minutes. The decrease in the effectiveness of TDS is 42.09%, BOD5 34.36% and COD 88.89%, while the decrease in the effectiveness of Fe and Mn was 55.2 % and 90 %. From the results that have been obtained indicate that electrocoagulation method can reduce pollutants which are contained in the peat water. The results of this process meet the standards of Health Ministers RI No 492/Menkes/Per/IV/2010. Keywords: peat water, electrocoagulation, aluminum electrodes
