“…The high microbial diversity observed (Delforno et al., ) represents a high genetic diversity and, consequently, a broad metabolic potential for several bioprocesses. Therefore, a wide application of granular sludge for nitrogen (Moura, Damianovic, & Foresti, ) and sulfide removal (Camiloti et al., ), hydrogen production (Penteado et al., ), anionic surfactant degradation (Okada et al., ), polychlorinated biphenyl (PCB) degradation (Gomes et al., ), and veterinary antimicrobial removal (Oliveira, Santos‐Neto, & Zaiat, ) has been observed.…”

“…The experimental conditions used were defined based on the study developed by Moura et al (2012) and Barana et al (2013) (Table 1). Nine trials were evaluated that differed by the aeration time in each cycle of 180 minutes and the recirculation ratio (Qr).…”

“…The authors assessed the impact of pH and found that pH was the key parameter for operational control in the reactor. The microbial population was characterized at a pH range from 2.3 to 0.8; at pHs above 1.3 Acidithiobacillus ferrooxidans was the dominant microorganism, whereas at pHs below 1.3 Leptospirillum ferrooxidans dominated.Water Environment Research, Volume 85, Number 10-Copyright © 2013 Water Environment FederationA newly configured acrylic fixed-bed reactor with a working volume of 6.1 L was used under conditions of continuous feeding and intermittent aeration (2 h aerated and 1 h non-aerated)(Moura et al 2012). The reactor was operated at three HRTs and the removals of COD and TN were 82% and 89%, respectively at an HRT of 12 h.Although high COD removal efficiencies of 85% and 88% were obtained for Phases II and III, respectively, low TN removals of 49% and 45% were obtained for HRTs of 8 and 10 h, respectively Mousavi et al (2012).…”
