Bioreactors for tissue engineering

open access: yes, 2023
Bioreactors have been widely used in various fields of biological production for many years. Their ability to provide a tightly controlled environment during the process and to allow for monitoring and intervention to the process parameters make them ...

Biomass effects on oxygen transfer in membrane bioreactors [PDF]

open access: yes, 2007
Ten biomass samples from both municipal and industrial pilot and full scale submerged membrane bioreactors (MBRs) with mixed liquor suspended solids concentrations (MLSS) ranging from 7.2 to 30.2 g L−1 were studied at six air-flow rates (0.7, 1.3, 2.3, 3,

Aeration and hydrodynamics in submerged membrane bioreactors [PDF]

open access: yes, 2011
Membrane bioreactor (MBR) is already a well-developed wastewater treatment process for both municipal and industrial applications. Nonetheless, membrane fouling remains a significant problem for its wider development.

The determination and origin of fibre clogging in membrane bioreactors [PDF]

open access: yes, 2011
Membrane channel clogging in membrane bioreactors (MBRs) has been largely unexplored by the research community, despite it being widely recognised as the main impediment to sustainable MBR operation by practitioners, and reflects the difficulty of ...

FLOCCULATION BIOREACTORS [PDF]

open access: yes, 2010
One of the main goals of bioprocess engineering is to increase the productivity of biotechnological processes and a vigorous progress has been observed in that field over the last decades. Fermentation based processes are not an exception and, in order to achieve those objectives, techniques such as the use of high cell density systems have been ...

Dynamical Modelling and Simulation of Waste water Filtration Process by Submerged Membrane Bioreactors [PDF]

open access: yes, 2009
A mathematical model was developed for the filtration process and the influence of aeration on Submerged Membrane Bioreactors. The dynamics of sludge attachment to and detachment from the membrane, in relation to the filtration and a strong intermittent ...

Effect of cytostatic drug presence on extracellular polymeric substances formation in municipal wastewater treated by membrane bioreactor [PDF]

open access: yes, 2010
The effect of the cyclophosphamide and its mean metabolites on extracellular polymeric substances (EPS) formation was investigated. Two lab-scale membrane bioreactors were followed in parallel (one with the cytostatic drugs, the second without ...

Membrane life estimation in full-scale immersed membrane bioreactors [PDF]

open access: yes, 2011
Limited quantitative available information exists regarding the robustness of membranes used in immersed membrane bioreactor (iMBR) applications, and no information on the relative contribution of the two main membrane failure modes of permeability ...

Numerical study of substrate assimilation by a microorganism exposed to fluctuating concentration [PDF]

open access: yes, 2012
In most modelling works on bioreactors, the substrate assimilation is computed from the volume average concentration. The possible occurrence of a competition between the transport of substrate towards the cell and the assimilation at the cell level is ...
