The effect of the hydraulic retention
time and the sulphate-total COD ratio on the performance
of an anaerobic biological process applied
to acid mine drainage water (AMD) was evaluated
using cheese whey as a carbon source. Laboratoryscale
fixed bed bioreactors operating at 25 ± 2 ºC
were used in the experiments. Maximum sulphate
reduction and hydrogen sulphide production were
achieved at a hydraulic retention time of 8 days and
at a sulphate-total COD ratio of 0.5. Under these
conditions, the sulphate removal was found to be
68.1% while the hydrogen sulphide production was
0.27 L/day. At the same time, the total COD removal
obtained was 55.4%.
