Anaerobic treatment of biscuit wastewater in an uasb-reactor. Akkoyunlu, A., Demir, I., Yueksel, E., & Eyvaz, M. FRESENIUS ENVIRONMENTAL BULLETIN, 16(9B):1201-1206, 2007. abstract bibtex The upflow anaerobic sludge blanket reactor (UASBR) is efficient in
treating wastewater, especially when dissolved organic matter is
present. In this study, a laboratory scale of an UASBR was configured
to treat biscuit wastewater. Hydraulic retention time (HRT), organic
loading and hydraulic loading parameters were used as design criteria
and wastewater parameters such as pH, alkalinity, chemical oxygen
demand (COD), suspended solids (SS), total volatile acid (TVA) and
total solids (TS) were investigated as performance criteria. Substrate
utilization rate in terms of COD, gas composition in terms of CH4 and
total volatile solids changing with depth in the reactor were also
determined. The COD removal rate was attained to be 92%. Methane gas
was about 60-65% of the biogas produced. Moreover, a mathematical
model was studied and kinetic coefficients were obtained for this
particular wastewater. Kinetic coefficient Y and endogenous decay
coefficient k(d) were obtained as 0.036 kg TVS/kg COD-rem and 4.084
day(-1), respectively.
