Improvement of the settling properties of Anammox sludge in an SBR

Monitoring the stability of an Anammox reactor under high salinity conditions

“…The SBR was operated in cycles of 6 h distributed in the following periods established according to Dapena-Mora et al [10]: continuous stirred feeding during 300 min; stirring without feeding during 30 min; settling for 20 min and effluent withdrawal for 10 min. The hydraulic retention time (HRT) was fixed at 1 day.…”

Biofilm and granular systems to improve Anammox biomass retention

“…The control of the pumps and different periods of the operational cycles was performed with a PLC system (CPU224, Siemens). Both reactors were operated in cycles of 6 h distributed in four periods: mixed fill (300 min), mix (30 min), settle (15 min) and draw (15 min) according to Dapena-Mora et al [9]. The exchange volume was fixed at 12.5% and 25% for SBR1 and SBR2, respectively.…”

Nitrogen removal performance of a hybrid anammox reactor

“…Biofilm type reactors, such as fixed bed, fluidized bed and gas lift reactors have initially been applied for anammox treatment (Van de Graaf et al, 1996;Strous et al, 1997;Sliekers et al, 2003). The sequencing batch reactor was also applied to anammox sludge cultivation (Strous et al, 1997(Strous et al, , 1999Dapena-Mora et al, 2004). Fixed-bed reactors using various types of biomass carriers, e.g., polyethylene (PE) sponge , polyester non-woven material (Furukawa et al, 2001), novel acrylic resin material (Qiao et al, 2009), poly (vinyl alcohol)-gel beads (Hoa et al, 2006) and polyethylene glycol gel (Isaka et al, 2007), were developed for stable immobilization of anammox sludge.…”
