| Abstract: | The effect of different organic loading rate (OLR) to an anaerobic reactor performance and sulphate reduction was investigated. Sulphate concentration in the feed varied from 100 to 3000 mg.L-1 and up to 97% removal efficiency was observed at OLR 0.43 - 1.23 kg COD.m-3.d-1. However, the removal efficiency showed some decline (to 53 – 67% removal) at OLR 1.53 – 3.73 kg COD.m-3.d-1, probably due to high sulphate concentration in the feed during this period. At a reactor OLR of 1.86 kg COD.m-3.d-1 (HRT 4 d), the soluble COD reduction was around 70 - 75%. Nevertheless, when the OLR was increased to 2.48 - 3.73 kg COD.m-3.d-1, the COD removal efficiency decreased to 45%. The microbial aspects of sulphate reducing bacteria (SRB) results indicated that sulfidogenic bacteria, such as Desulfovibrio, had contributed substantially to the treatment process (around 16 – 36% when the reactor was operated at OLR 0.86 – 2.98 kg COD.m-3.d-1). |
