Journal ArticleDOI
Membrane bioreactor fouling in sub-critical filtration conditions: a local critical flux concept
TL;DR: An increase occurs in the rate of circulation in the pores which remain open, which may reach critical local filtration conditions, resulting in the formation of deposits which are reversible but induce an abrupt change in transmembrane pressure.
Journal ArticleDOI
Influence of macromolecule adsorption during filtration of a membrane bioreactor mixed liquor suspension
TL;DR: In this paper, the effect of adsorption on membrane fouling during filtration of a membrane bioreactor (MBR) mixed liquor suspension was quantified using β-lactoglobulin solutions.
Journal ArticleDOI
Effect of reeds and feeding operations on hydraulic behaviour of vertical flow constructed wetlands under hydraulic overloads.
TL;DR: The study of the hydraulic limits of reed beds, based on the knowledge of hydrodynamics in unsaturated porous media, shows the ability of the system to accept flow overloads and suggests new hydraulic limits with accompanying sizing rules and operational recommendations according to the level of deposit on the filter surface.
Journal ArticleDOI
Hydrodynamic control of bioparticle deposition in a MBR applied to wastewater treatment
TL;DR: In this paper, the authors studied fouling for tubular ceramic ultrafiltration (MWCO 300kD) membranes during activated sludge filtration under constant flux conditions, and revealed the major role of convective backtransport phenomena in fouling processes.

Nanofiltration membrane bioreactor for removing pharmaceutical compounds

TL;DR: The two antibiotics are weakly degraded even with acclimated sludge, and only a small fraction of these compounds was retained when the fouling of the membrane increased, so the hypothesis of this study lies in the development of NF membrane and its cut-off support in order to retain micropollutants and increase micropolutant concentration in the bioreactor.
