2019年12月1日 · The compact microbial structure of AGS allows establishing new BNR pathways, which minimizes process units and resource inputs. Short-cut BNR pathway (nitritation--denitritation) reduces O 2 and organic carbon, respectively, by 25% and 40% as

2023年10月10日 · This study investigated AGS formation and BNR pathways while treating real domestic wastewater in a 2 m 3 pilot-scale granular sequencing batch reactor (gSBR) operated without and with granular activated carbon (GAC) particles. The gSBRs were operated under tropical climate (T ≈ 30 °C) for >4-years to evaluate the effect of GAC addition on ...

2022年2月1日 · This study investigated the role of charcoal particles and substrate type on cultivation of AGS and establishment of BNR pathways. Experiments were performed on granulation in lab-scale SBRs using different carbon sources such as HAc, HPr, and HAc-HPr with and without activated carbon (AC) particles.

2021年12月14日 · Putative HN bacteria (i.e., Thauera (29–36%) and Flavobacterium (18–25%)) were enriched in aerobic granular sludge (AGS) regardless of the granular reactor operation mode. Enrichment of HN organisms in the AGS was suspected to be mainly due to granulation, possibly due to the floc-forming ability of HN species.

2022年12月22日 · Aerobic granular sludge (AGS) process is an emerging biotechnology for effective and sustainable treatment of domestic and industrial wastewaters. Here, the response of AGS to variation in temperature was investigated in terms of granular stability and biological nutrient removal (BNR) pathways.

Aerobic Granular Sludge (AGS) Technology is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. An aerobic granular biomass is comprised of compact granules that provide advantages compared to other

2024年2月29日 · Highlighting the core bacterial microbiome of BNR AGS and its comparison with conventional activated sludge is key for the subsequent understanding of microbial selection mechanisms. The delineation of a conceptual model of the AGS ecosystem can also sustain investigations of metabolic functions of targeted populations.

2022年5月1日 · A mass and energy balance model for an AGS-based in Utrecht (The Netherlands) showed that when AD of waste granular sludge was combined with chemically enhanced primary treatment (CEPT), one-third of the influent COD may be recovered as energy, doubling the on-site energy recovery when compared …

External additives such as activated carbon (AC) attracted interest for accelerating AGS formation. However, the roles of AC in granulation and biological nutrient removal (BNR) are not understood.

The microbead-like aerobic granular sludge (AGS) in the pilot’s two reactors (the white cylinders above) was started using granules of AGS from an AquaNereda® unit in Illinois. The Noman M. Cole Jr. Pollution Control Plant (NCPCP) in Fairfax County, Virginia, plans to expand its capacity from 67 million gallons per day (mgd) to 80 mgd.
