Influence of organic loading on an anaerobic sequencing biofilm batch reactor (ASBBR) as a function of cycle period and wastewater concentration

AnSBBR applied to the treatment of wastewater from a personal care industry: Effect of organic load and fill time

“…It can be seen that for the highest applied organic load in the AnSBBR by Siman et al (2004), i.e. 5.4 gCOD/(L d), the kinetic parameter was inferior to that obtained in the current work [at 5.8 gCOD/(L d)].…”

“…Comparison of the results obtained in the current work with those obtained by Siman et al (2004) and Chebel et al (2006) shows that the AnSBBR treating wastewater from a personal care industry obtained higher removal efficiency and lower residual organic matter concentration at all OLRs. Comparison with the results of Bezerra et al (2007) showed that only at OLR 3.0 gCOD/ (L d) this did not occurred.…”

“…C A is the organic matter concentration in the influent, t c cycle length, OLR is the organic loading rate, C SR is the residual organic matter concentration, 3 is the removal efficiency in terms of filtered samples, k 1S is the first order kinetic parameter, V is the total treated volume per cycle, V R is the renewed or treated influent volume per cycle. Siman et al (2004) used an AnSBBR submitted to organic overload of a wastewater based on carbohydrates/proteins/lipids. The reactor was fed with 2 L synthetic influent with concentrations of 500-2000 mgCOD/L and operated in 8 and 12-h batches.…”

“…Cases where immobilized biomass is used (AnSBBR) include the treatment of wastewaters such as synthetic wastewater (Ratusznei et al, 2001;Siman et al, 2004), cheese whey (Orra et al, 2004;Damasceno et al, 2007;Bezerra et al, 2007), automobile industry (Oliveira et al, 2008), and textile wastewater (Sirianuntapiboon et al, 2007b).…”

The "Chemical Oxygen Demand / Total Volatile Acids" Ratio as an Anaerobic Treatability Indicator for Landfill Leachates

“…As this configuration presented good results treating synthetic wastewaters (removal efficiency up to 86%), the AnSBBR started to be studied and developed (Ratusznei et al, 2003;Rodrigues et al, 2003;Cubas et al, 2004;Pinho et al, 2004;Siman et al, 2004;Bezerra et al, 2010;Costabile et al, 2010). The AnSBBR was also tested and optimized with many types of wastewaters, including diluted whey (Damasceno et al, 2007), sewage (Sarti et al, 2007) wastewater of the personal-care industry (Oliveira et al, 2009), biodiesel production effluent (Selma et al, 2010;Bezerra et al, 2010), sucrose-based wastewater (Manssouri et al 2013) among other studies for optimization and improvement of the AnSBBR Silva et al, 2011;Vich et al, 2011).…”
