This paper presents MBR performances observed under steady and unsteady state conditions where influent and permeate flow rates were punctually and simultaneously increased. Experiments were performed in a submerged membrane bioreactor presenting a 50 L working volume. Two capillary membrane modules

If the notion of sustainable critical flux can be analysed in regards to hydrodynamics conditions imposed closed to a defined membrane surface taking into account the suspension characteristics, it is important to integrate the actual heterogeneity of filtration conditions relatively to the individu

A membrane bioreactor used for denitrification of a synthetic substrate was studied in term of membrane fouling. For standard pH and temperature conditions, subcritical conditions were defined to ensure the process stability. The stepwise method was used to determine the critical flux for the deposi

A hybrid process combining electrodialysis and a membrane bioreactor was investigated to treat ground waters with excessive nitrate concentrations. Electrodialysis (ED) allowed the nitrate separation producing, on one hand, partially demineralized waters whose ion concentrations were in agreement wi
