Treatment of low-strength soluble wastewater using an anaerobic baffled reactor (ABR)

Effect of Sulfate Loading Rate and Organic Loading Rate on Anaerobic Baffled Reactors Used for Treatment of Sanitary Landfill Leachates

“…ABRs exhibit a plug flow behavior that, in combination with compartmentalization, provokes staging of VFA degradation Vossoughi et al, 2003;Krishna et al, 2009). Previous reports have indicated that, when an ABR is fed with sulfate, more than a half of the effluent OM and sulfate is removed in the first compartment.…”

Hydrogen production using an anaerobic baffled reactor – Mass balances for pathway analysis and gas composition profiles

“…One down-and one up-flow section is what constitutes one compartment. Using this setup, the flow can be considered as being intermediate between plug-flow and perfectly mixed [35]. During fermentation the upflowdownflow-ratio was 1:1.…”

Response of performance of an anammox anaerobic baffled reactor (ABR) to changes in feeding regime

“…1 (where D = longitudinal dispersion coefficient, m 2 s À1 , u = fluid velocity, m s À1 , and L = length of reactor, m), indicates a perfectly mixed system, whereas a small dispersion number, D/ uL ! 0, indicates a plug-flow system (Grobicki and Stuckey, 1992;Gopala Krishna et al, 2009).…”

“…A typical ABR consists of a series of vertical baffles that direct wastewater under and over baffles as it passes from the inlet to the outlet. Whether treating heavy oilproduced water or low-strength soluble wastewater (Gopala Krishna et al, 2009;Ji et al, 2009), ABRs have always exhibited stable reactor performance. However, problems can occur during reactor operation as a result of plug-flow characteristics.…”
