- Evaluation of the impacts of model-based operation of SBRs on activated sludge microbial community. Sin, G.; Govoreanu, R.; Boon, N.; Schelstraete, G.; Vanrolleghem, P. A. // Water Science & Technology;2006, Vol. 54 Issue 1, p157
Impact of model-based operation of nutrient removing SBRs on the stability of activated sludge population was studied in this contribution. The optimal operation scenario found by the systematic model- based optimisation protocol of Sin et a!. (Wat. Sci. Tech., 2004, 50(10), 97-105) was applied...
- The effect of upflow air velocity on the structure of aerobic granules cultivated in a sequencing batch reactor. Tay, J. H.; Liu, Q. S.; Liu, Y. // Water Science & Technology;2004, Vol. 49 Issue 11/12, p35
The effect of upflow air velocity on the formation and structure of aerobic granules was studied in three column sequencing batch reactors. Upflow aeration would be the major cause of hydrodynamic shear force in the column reactor. Results showed that high upflow air velocity resulted in more...

- Treatment of dairy effluents in an aerobic granular sludge sequencing batch reactor. Schwarzenbeck, N.; Borges, J. M.; Wilderer, P. A. // Applied Microbiology & Biotechnology;Apr2005, Vol. 66 Issue 6, p711
Aerobic granular sludge can successfully be cultivated in a sequencing batch reactor (SBR) treating dairy wastewater. Attention has to be paid to the fact that suspended solids are always present in the effluent of aerobic granular sludge reactors, making a post-treatment step necessary....
- A study of aerobic digester performance with the use of methanol for biological nutrient removal in a full-scale sequencing batch reactor. Koh, Jeffrey J.H; Mavinic, Donald S; Oldham, William K; Meisen, Axel; Nuttall, Steven J // Journal of Environmental Engineering & Science;Nov2002, Vol. 1 Issue 6, p439
The primary goal of this research was to determine whether the use of methanol in a full-scale sequencing batch reactor (SBR) affected the subsequent aerobic sludge digester performance. The methanol injection into an experimental SBR resulted in a significant increase in the solids level in the...
