The performance of an anaerobic moving bed
biofilm reactor (MBBR) containing AnoxKaldnesTM K5 model for
the treatment of raw acid mine drainage (AMD) was investigated
for the reduction of sulphate and chemical oxygen demand using a
consortium of sulphate reducing bacteria (SRB) dominated by
Proteobacteria. The MBBR was enriched for 4 weeks, followed by
introduction of raw AMD and sampling at intervals for 7 weeks.
Maximum removal efficiency of COD was 99 % followed by 75 %
sulphate reduction. The results showed that the bio-carrier is more
suited for the COD reduction
