“…Concentrations of TS and TVS in the polyurethane foam inside the AnSBBR, listed in Table 5, did not present significant differences with changing conditions, indicating reactor stability and efficiency of the inert support in maintaining the biomass adhered to its surface during the assays with mechanical stirring and different fill times, confirming in pilot-scale the results obtained in lab-scale [9,10,13,15,19].…”

Many lab-scale studies have been carried out regarding the effect of feed strategy on the performance of anaerobic sequencing batch reactors (ASBR); however, more detailed pilot-scale studies should be performed to assess the real applicability of this type of operation. Therefore, the objective of this work was to assess the effect of feed strategy or fill time in a 1-m(3) mechanically stirred pilot-scale sequencing batch reactor, treating 0.65 m(3) sanitary wastewater in 8-h cycles at ambient temperature. Two reactor configurations were used: one containing granular biomass (denominated ASBR) and the other immobilized biomass on polyurethane foam as inert support (denominated anaerobic sequencing batch biofilm reactor (AnSBBR)). The reactors were operated under five distinct feed strategies, namely: typical batch and fed-batch for 25%, 50%, 75%, and 100% of the cycle length. Stirring frequency in the ASBR was 40 rpm with two flat-blade turbine impellers and 80 rpm in the AnSBBR with two helix impellers. The results showed that both the ASBR and AnSBBR when operated under typical batch, fed-batch for 50% and 75% of the cycle length, presented improved organic matter removal efficiencies, without significant differences in performance, thus showing important operational flexibility. In addition, the reactors presented operation stability under all conditions.

“…The immobilization procedure for the AnSBBR consisted of crushing the sludge in a mixer, completely immersing the foam (inert support) with the obtained suspension, followed by homogenization and 2-h rest [15]. Poorly adhered solids were washed off and the medium drained.…”

“…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).…”

-In some operational circumstances a fast evaluation of landfill leachate anaerobic treatability is necessary, and neither Biochemical Methane Potential nor BOD/COD ratio are fast enough. Looking for a fast indicator, this work evaluated the anaerobic treatability of landfill leachate from São Carlos-SP (Brazil) in a pilot scale Anaerobic Sequence Batch Biofilm Reactor (AnSBBR). The experiment was conducted at ambient temperature in the landfill area. After the acclimation, at a second stage of operation, the AnSBBR presented efficiency above 70%, in terms of COD removal, utilizing landfill leachate without water dilution, with an inlet COD of about 11,000 mg.L -1 , a TVA/COD ratio of approximately 0.6 and reaction time equal to 7 days. To evaluate the landfill leachate biodegradability variation over time, temporal profiles of concentration were performed in the AnSBBR. The landfill leachate anaerobic biodegradability was verified to have a direct and strong relationship to the TVA/COD ratio. For a TVA/COD Total ratio lower than 0.20, the biodegradability was considered low, for ratios between 0.20 and 0.40 it was considered medium, and above 0.40 it was considered high.
