High organic loading influences the physical characteristics of aerobic sludge granules
Aims: The effect of high organic loading rate (OLR) on the physical characteristics of aerobic granules was studied.
Specific layers in aerobically grown microbial granules
Aims: To determine the optimal size of aerobically grown granules for wastewater treatment by measuring specific layers within the granules.
Size-effect on the physical characteristics of the aerobic granule in a SBR
In this study, aerobic granules from a sequencing batch reactor were mechanically separated into various size-categories in order to investigate their physical properties, including sludge volumetric index (SVI), settling velocity (sv), specific surface hydrophobicity, granule strength, total solids, percentage volatile solids and other structural properties.

Presence of Anaerobic Bacteroides in Aerobically Grown Microbial Granules
This is the first study to use a suite of culture-independent techniques to report the presence of a defined species of anaerobic bacteria in aerobically grown microbial granules. Expand
Rapid cultivation of stable aerobic phenol-degrading granules using acetate-fed granules as microbial seed.
This is the first study to demonstrate the benefits of using aerobic granules cultivated on benign substrates as microbial seed to produce granules to degrade toxic substrates, and can be extended to granule-based applications involving other toxic chemicals and other types of high-strength industrial wastewaters, where rapid reactor start-up and system stability are key considerations.

Reactor performance and membrane filtration in aerobic granular sludge membrane bioreactor
Integrated operation between submerged hollow fiber membrane filtration and a sequencing aerobic sludge blanket reactor (SASBR) led to a novel aerobic granular sludge membrane bioreactor (AGMBR).Expand
Start-up, microbial community analysis and formation of aerobic granules in a tert-butyl alcohol degrading sequencing batch reactor.
We demonstrate that compact well-settling aerobic granules can be developed in a sequencing batch reactor (SBR) for the biological removal of tert-butyl alcohol (TBA) using a strategy involving stepExpand
Biodegradation of p-nitrophenol by aerobic granules in a sequencing batch reactor.
The results in this study demonstrate that it is possible to use aerobic granules for PNP biodegradation and broadens the benefits of using the SBR to target treatment of toxic and recalcitrant organic compounds. Expand
Changes in structure, activity and metabolism of aerobic granules as a microbial response to high phenol loading
At the highest loading applied, the anabolism and catabolism of microorganisms were regulated such that phenol degradation proceeded exclusively via the meta pathway, apparently to produce more energy for overstimulation of protein production against phenol toxicity. Expand
Effect of Organic Loading Rate on Aerobic Granulation. I: Reactor Performance
The effect of organic loading rate (OLR) on the aerobic granulation process was investigated using laboratory-scale sequential aerobic sludge blanket reactors (SASBRs). Reactors R1, R2, R3, and R4Expand
