This work aims to characterise the impact of hydrodynamics on sludge properties and consequently on fouling mechanisms in side-stream membrane bioreactors (MBRs). Two side-stream processes which generate very different shear stresses are compared, without filtration. This operating mode permits specific quantification of the impact of the external loop (and of induced shear stress) on floc structure/morphology, supernatant quality and fouling propensity. The study shows that low constraints (7… CONTINUE READING
