Diffusion in Aerobic Granular Sludge
2022A large part of the wastewater produced worldwide is discharged without any treatment. This has several negative consequences, including the spread of diseases and contamination of the environment. One method to treat wastewater is called aerobic granular sludge (AGS), an advanced, compact technology that uses granules.

Factors influencing the density of aerobic granular sludge
Applied Microbiology and Biotechnology, 2012In the present study, the factors influencing density of granular sludge particles were evaluated. Granules consist of microbes, precipitates and of extracellular polymeric substance. The volume fractions of the bacterial layers were experimentally estimated by fluorescent in situ hybridisation staining. The volume fraction occupied by precipitates was

Performance of aerobic granular sludge in different bioreactors
Environmental Technology, 2013Inoculated sludge from the Brewery wastewater treatment plant was cultured in a sequencing batch reactor (SBR). The granular sludge was then used to process the artificial simulation wastewater to compare the performance and efficiency of the granular sludge in organic matter removal by using SBR and granular membrane bioreactor (GMBR).

Tolerance to organic loading rate by aerobic granular sludge in a cyclic aerobic granular reactor
Bioresource Technology, 2015Sodium acetate as carbon source, tolerance to organic loading rate (OLR) by aerobic granular sludge in a cyclic aerobic granular reactor (CAGR) was investigated by gradually increasing the influent COD. AGS could maintain stability in the continuous flow reactor under OLR⩽15kg/m(3)d in the former 65 days, and SVI, granulation rate, average particle ...
