| Summary: | Inadequacy of nitrogenous resource
and buffering ability were detected as reverting
failure in previous work treating petrochemical
wastewater (PWW) in anaerobic continuous
stirred tank reactors. The aim of this study is to
explore the use of ammonium bicarbonate
(NH4HCO3) as supplementation assuring
nitrogenous supply and buffering requirement. To
observe the effect of strong base such as
NH4HCO3 on the anaerobic process, a set of
dosing up to 40 mg L-1 was examined. The
outcomes were assessed in terms of biogas yield. It
was observed that10 mg L-1 dosing was the
optimal dosing without affecting methanogenesis.
Furthermore, mathematical calculation explained
that this optimum dosing can enhance biogas
yield up to 27.77% compared to control PWW
digestion. Results showed an obvious financial
advantage to make the industrial application
feasible.
