Peat water is surface water that flooded an area formed by the files of organic material over a long period. The characteristics of the peat water is a low pH (3-4) that is highly acidic, has a high organic content, high levels of iron (Fe) and manganese (Mn), as well as yellow or dark brown (concentrated). One of the peats is formed in the Integrated Independent City, Ogan Ilir Regency, South Sumatera. The formed feat water contains Fe and Mn high enough for it to be analyzed for the peat water treatment to reduce the levels of Fe and Mn metal using electrocoagulation. The electrocoagulation is performed in batch with electrodes dimensions are 18cm x 6.5cm x 0.2cm and the distance between is the electrodes 1cm. The aluminum electrodes are contacted with peat water by varying the current density of 20 A/m2, 40 A/m2, 60 A/m2 and 80 A/m2 and varying 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 and decrease the effectiveness of each parameter occurs at 20 A/m2 current density with the processing time of 120 minutes. The decrement of TDS effectiveness is 42.09%, BOD5 34.36% and COD 88.89%, while the decrement of the effectiveness of the Fe and Mn metal content were 55.2 % and 90 %, respectively. The results indicate that electrocoagulation method can reduce water pollutants contained in the peat water. The results of this processing have fulfilled the standards of the Ministry of Health.
