Size of biological flocs in activated sludge systems: Influence of hydrodynamic parameters at different scales
Autor: Anne Goubet, Camilo Duran Quintero, Sylvain Pageot, Sylvie Gillot, Yoan Pechaud, Yannick Fayolle
Publikováno v: Journal of Environmental Chemical Engineering
Journal of Environmental Chemical Engineering, Elsevier, 2021, 9 (4), pp.105427. ⟨10.1016/j.jece.2021.105427⟩
In conventional activated sludge (CAS) systems and membrane bioreactors (MBR), aeration, mixing and filtration are affected by various properties of activated sludge (AS) and especially viscosity and morphological properties of flocs. The aim of the

Limitations imposed by conventional fine bubble diffusers on the design of a high-loaded membrane bioreactor (HL-MBR)
Autor: Marin Matošić, Aridai Herrera, Damir Brdjanovic, Chris Milligan, Carlos M. Lopez-Vazquez, Hector A. Garcia, Dennis Livingston, Sang Yeob Kim, Josip Ćurko
Publikováno v: Environmental Science and Pollution Research. 26:34285-34300
The operation of membrane bioreactors (MBRs) at higher than usual mixed liquor suspended solids (MLSS) concentrations may enhance the loading rate treatment capacity while minimizing even further the system's footprint. This requires operating the MB

Three decades of oxygen transfer tests in clean water in a pilot scale test tank with fine-bubble diffusers and the resulting conclusions for WWTP operation
Autor: Maximilian Schwarz, Martin Wagner, Justus Behnisch
Publikováno v: Water Practice and Technology. 15:910-920
We summarized the experience from three decades of oxygen transfer testing and aeration research at the Technical University of Darmstadt to validate the oxygen transfer efficiency of modern fine-bubble diffusers. A total of 306 oxygen transfer tests

Oxygen Transfer in Two-Stage Activated Sludge Wastewater Treatment Plants
Autor: Schwarz, Maximilian, Behnisch, Justus, Trippel, Jana, Engelhart, Markus, Wagner, Martin
Publikováno v: Water, Vol 13, Iss 1964, p 1964 (2021)

Volume 13
Issue 14
Aeration is an energy-intensive process of aerobic biological treatment in wastewater treatment plants (WWTP). Two-stage processes enable energy-efficient operation, but oxygen transfer has not been studied in depth before. In this study, α-factors

Evaluation of cleaning techniques in fine bubble diffuser membranes used in aerobic processes for wastewater treatment
Autor: Diaz Esteban, Diego Sebastian, Suarez Angarita, Julieth Daniela
La aireación es el principal consumidor de electricidad en el tratamiento de las aguas residuales municipales, presente en ciertos procesos biológicos, como los lodos activados, los cuales demandan entre el 50-70% de los costos de la energía neces

Oxygen transfer performance of a supersaturated oxygen aeration system (SDOX) evaluated at high biomass concentrations
Autor: Aridai Herrera, Carlos M. Lopez-Vazquez, Marin Matošić, Damir Brdjanovic, Josip Ćurko, Sang Yeob Kim, Hector A. Garcia, Chris Milligan
Oxygen transfer in wastewater treatment is significantly influenced by the mixed liquor suspended solids (MLSS). The effect is more pronounced at MLSS concentrations higher than 20 g L−1 when supplying air by conventional diffused aeration systems.

Publikováno v: Water Science and Technology. 76:1595-1602
Achieving energy neutrality has shifted focus towards aeration system optimization, due to the high energy consumption of aeration processes in modern advanced wastewater treatment plants. A study on fine bubble diffuser fouling and mitigation, quant

Oxygen transfer improvement in MBBR process
Autor: Maria Cristina Collivignarelli, Giorgio Bertanza, Alessandro Abbà
Publikováno v: Environmental science and pollution research international. 26(11)
In the last years, the upgrading of wastewater treatment plants (WWTPs) could be required in order to comply with the more stringent regulation requirements. Nevertheless, the main issue is related to the surface availability. A proper solution could
