Lousada Ferreira, M.D.C. (author), Van Lier, J.B. (author), Van der Graaf, J.H.J.M. (author)The relation between activated sludge filterability and mixed liquor suspended solids (MLSS) concentration in membrane bioreactors (MBRs) is framed in a single hypothesis, explaining results seemingly contradictory. A total of 44 activated sludge samples were collected and analyzed on a variety of parameters, i.e. filterability, MLSS...journal article 2015

Odriozola, Magela (author), Abraham, E. (author), Lousada Ferreira, M. (author), Spanjers, H. (author), van Lier, J.B. (author)The application of cationic polymers to enhance membrane fluxes in anaerobic membrane bioreactors has been proposed by several authors. However, literature shows contradictory results on the influence of those chemicals on the biological activity. In this research, we studied the effect of a cationic polymer on the production of methane from...journal article 2019

Odriozola, Magela (author), Morales, Nicolás (author), Vazquez-Padin, Jose R. (author), Lousada Ferreira, M. (author), Spanjers, H. (author), van Lier, J.B. (author)Cationic polymers have proven to be suitable flux enhancers (FEs) in large‐scale aerobic membrane bioreactors (MBRs), whereas in anaerobic membrane bioreactors (AnMBRs) research is scarce, and so far, only done at lab‐scale. Results from MBRs cannot be directly translated to AnMBRs because the extent and nature of membrane fouling under...journal article 2020

Odriozola, Magela (author), Lousada Ferreira, M. (author), Spanjers, H. (author), van Lier, J.B. (author)Fouling is a major challenge for the economic feasibility and applicability of membrane bioreactors. Several strategies have been proposed for fouling control, and among them, addition of flux enhancers (FE) have shown promising results. Previous research revealed a high variability of the required optimal dosage of FE for different types of...journal article 2021
