TLDR
Aerobic granular sludge was observed in a Sequencing Batch Reactor (SBR) in which a synthetic urban wastewater containing sodium acetate as an organic substrate was fed, and dissolved oxygen (DO) was controlled at low concentration (0.7-1.0 mg/l) as mentioned in this paper.About:

The essential role of hydrodynamic shear force in the formation of biofilm and granular sludge
Yu Liu,Joo-Hwa Tay +1 more
TL;DR: It can be concluded that the knowledge regarding the effects of hydrodynamic shear force on biofilms and granules is far from complete and much research is still needed to fully understand the relevant mechanisms.

Aerobic granular sludge: Recent advances
TL;DR: An up-to-date review on recent research development in aerobic biogranulation technology and applications in treating toxic industrial and municipal wastewaters and attempts to shed light on the fundamental understanding in aerobic granulation by newly employed confocal laser scanning microscopic techniques and microscopic observations of granules.

State of the art of biogranulation technology for wastewater treatment.
Yu Liu,Joo-Hwa Tay +1 more
TL;DR: This review hopes to provide a platform for developing novel granules-based bioreactors and devising a unified interpretation of the formation of anaerobic and aerobic granules under various operation conditions.
Journal ArticleDOI
Simultaneous COD, nitrogen, and phosphate removal by aerobic granular sludge
TL;DR: Experimental results strongly suggest that P-removal occurs partly by (biologically induced) precipitation, and monitoring the laboratory scale reactors for a long period showed that N- Removal efficiency highly depends on the diameter of the granules.
Journal ArticleDOI
Aerobic granulation in a sequencing batch airlift reactor.
TL;DR: The performance of the intermittently fed SBAR was compared to that of the continuously fed biofilm airlift suspension reactor (BASR) and the most importance difference was that the density of the granules in theSBAR was much higher than thedensity of the biofilms in the BASR.

Groundwater denitrification using an upflow sludge blanket reactor
TL;DR: In this paper, the results of groundwater denitrification experiments using a USB reactor, with ethanol as the carbon source, indicate that it can efficiently treat affected water, but this type of reactor was found to be strongly affected by the hardness of the water as a result of changes in the mineral fraction of the granules.

The Implementation of Bulking Control in the Design of Activated Sludge Systems
TL;DR: In this article, the authors discuss the factors affecting the growth of most common filamentous microorganisms, including wastewater composition, biomass retention time, actual substrate concentration in reactor, operational parameters in reactor (DO and nutrients concentration, pH, temperature).
Journal ArticleDOI
Modeling the activated sludge floc microenvironment
TL;DR: Results indicate rapid progression toward minimum porosity with relatively slow expansion of the microcolony surface, which may emphasize the difference between the mechanisms involved in the structural development of microcolonies and larger scale aggregates.
