Abstract

Successive alkalinity producing system (SAPS) is one of the most preferred passive treatment system for acid mine drainage. Sulfate reducing bacteria (SRB) in SAPS make anaerobic environment needed to successive alkalinity production of limestone. It was observed that the SRB activity was most apparent at 36 °C and sulfate removal rate of up to 86% was achieved at this temperature when SAPS had 8 cm thickness of mushroom compost layer and hydraulic retention time (HRT) of 8 days. The sulfate removal rate was directly proportional to the temperature and it significantly decreased at 1 °C. The unexpected observation on the increased effluent sulfate concentration at 1 °C was due to the effect of sulfate elution from the mushroom compost. Iron removal rate was governed by both temperature and thickness of the mushroom compost layer. Finally, cultivation experiments revealed that SRB growth was significantly influenced by the temperature. The results of the present study suggest that the temperature directly influences on the SRB growth and subsequently controls the treatment efficiency of SAPS.
