Aerobic granular sludge in continuous flow reactors
Aerobic granular sludge (AGS) is an energy efficient and compact biological wastewater treatment process. There is only one commercially available AGS technology which utilizes sequencing batch reactors (SBR). Many existing wastewater treatment facilities consist of long, continuous flow reactors that would not be readily suitable for retrofit to SBR. Therefore, a continuous flow process is preferred for municipalities that cannot economically invest in the only commercially available SBR technology (i.e., Nere-da®). Lab- and pilot-scale experimentation has demonstrated that stable granulation can be achieved in a continuous flow configuration GT suitable for retrofit into existing infrastructure. An anoxic/anaerobic/aerobic configuration can be designed and stably operated for conversion of flocculent biomass to AGS Preliminary pilot-scale results on primary effluent from a municipal wastewater treatment facility indicated that granules of 0.2-0.5 mm, SVI<75 mL/g, and SV30 min/SVI5 min>70% can be formed within a month of steady operation. |
