ESTUARY SEDIMENT TREATMENT FOR REDUCING SULFATE IN ACID MINE WATER
Fahruddin, F., A. Abdullah, Nurhaedar, and N. La Nafie.
Environment and Natural Resources Journal 18(2):191-199(2020)
Estuary sediments were used as a source of sulfate-reducing bacteria inoculums to reduce sulfate in acid mine water in a column bioreactor. Treatment T1 containing sediment and compost was compared to treatments T2 (sediment), T3 (compost), and the T4 control treatment containing only acid mine water. Treatment T1 reduced sulfate concentrations by 78%, compared to 56% in T2, 21% in T3, and 5% in T4. The reduction of sulfate was followed by increases in pH where T1 reached a pH value of 7.1, compared to treatments T2 and T3 which had pH values <5.5. Treatment T4 had a pH of 2.2. The reduced sulfate and increased pH were also followed by an increase of SRB growth, especially in T1. https://ph02.tci-thaijo.org/index.php/ennrj/article/view/239889/163571
