Description of new single-chamber continuous-flow reactors of aerobic granular sludge: Technical and biological study
نویسندگان
چکیده
Aerobic granular sludge reactors usually operate in sequential batch mode, although this configuration limits the treatment of large volumes wastewater, and they require a storage system. To implement technology at full-scale, it would be necessary to design simple compact continuous-flow bioreactor able treat larger wastewater. In study, four aerobic single-chamber (R1, R2, R3 R4) were designed operated lab scale evaluate select that achieves high organic matter removal performance while maintaining stable granulation for long-term operation, promoting washout filamentous microorganisms. Results confirmed including lateral decanter (R1), was work steady state without loss biomass reached 95% performance. Its granules had excellent compaction, with settling velocity values above 100 m·h?1. The R1 also allowed rapid adaptation therefore fast start-up (11 days). preliminary study suggested new could promising its implementation full scale. For that, future research is required optimise current model determine most suitable operational parameters domestic wastewater

Dynamic Modeling of Granular Sludge in UASB Reactors
n this paper, a mathematical model has been derived to predict the granulation time of anaerobic sludge in UASB reactors. In the proposed model, some physical, chemical and biological parameters affecting the granulation phenomena have been considered. To validate the model, 12 pilot-scale experiments in 4 UASB reactors are carried out and the results are discussed here. The reactors are starte...

This advanced nutrient removal process can reduce footprint up to 75% and energy up to 50% when compared to conventional activated sludge systems. One of the defining characteristics of the granule is rapid settling which in turn allows for an increase in the biomass concentration. The granules are comprised of true biomass and do not require carriers. The layered microbial community that forms...

In recent years, a significant part of research on wastewater treatment has focussed on development of compact systems. Wastewater treatment plants (WWTP) can be designed compact when biomass is maintained in the system without the use of conventional settling tanks as in flocculated activated sludge systems. Examples are developments in the field of Membrane BioReactors, Biological Aerated Fil...
