USE OF ORGANIC MATERIALS WETLAND TO IMPROVING THE CAPACITY SULFATE REDUCTION BACTERIA (SRB) OF REDUCE SULFATE IN ACID MINE WATER (AMW)

摘要

Increasing mining activities in several regions in Indonesia, began to face problems, namelyudof environmental pollution. One of the mining waste that is liquid sulfur, or acid mine water, which canudlower the pH of the water and dissolves heavy metals. Countermeasures for the chemical method is touduse lime, but this is less effective. The method is good and is environmentally friendly way by usingudbiological bacteria sulphate reduction bacteria (SRB) that naturally there are many in the sedimentudwetland. Goal of this research is to find the type of sediment wetland most effectively increase the pHudand decrease the concentration of sulphate in acid mine water. The sediment wetland is usedudmangroves, swamp, rice fields and beaches. Treatment bioreaktor made on the filled with sedimentudunderneath the compost is given further incubation for 50 days. The observation of pH and content ofudsulphate based on the value of OD spectrophotometer and known pH increased to the highest in the pHudof 6,9 is in the swamp sediment treatment, while the only other treatment until the pH 5,8-6,4.udIncreasing the pH in accordance with the decrease in the rate of SO4 is most sharply in the swampudsediment treatment as well as the most effective treatment.
