Hydrodynamic control of bioparticle deposition in a MBR applied to wastewater treatment
The study of fouling for tubular ceramic ultrafiltration (MWCO 300 kD) membranes during activated sludge filtration under constant flux conditions led to the experimental identification of two fouling processes: (1) At low recirculation velocity (0.5 m/s; Re∼1200), sludge floc particles were deposit...

| description | The study of fouling for tubular ceramic ultrafiltration (MWCO 300
kD) membranes during activated sludge filtration under constant flux conditions led to the experimental identification of two fouling processes: (1) At low recirculation velocity (0.5
m/s;
Re∼1200), sludge floc particles were deposited on the membrane surface and this cake layer provoked a very quick increase of hydraulic resistance (>10

m/s;
Re∼9000), floc was not deposited. Filtration was stable for several days even with high fluxes (75–150

Mechanism models (shear induced diffusion, inertial lift, surface transport) led to a very good qualitative description of these results, and revealed the major role of convective backtransport phenomena in fouling processes. |
