ABSTRACT
The process performance of simultaneous anaerobic sulfide and nitrate removal was studied. The results showed that the process held a high sulfide and nitrate removal loading rate of 3.73kg/(m3 x d) and 0.80kg/(m3 x d), respectively, under steady state. It was capable of tolerating high influent substrate concentration (580mg/L and 110mg/L) with the optimum substrate concentration of 280mg/L and 67.5mg/L. It was capable of tolerating short hydraulic retention time (HRT) with the optimum HRT of 0.13d. Careful operation was needed when HRT was shortened because the process performance was deteriorated abruptly.
