This study was performed to investigate the effectiveness of submerged microfiltration to harvest both a marine diatom Phaeodactylum tricornutum and a Chlorella vulgaris in a recently developed magnetically induced membrane vibrati ng (MMV) system. We assess the filtration performance by conducting the improved flux step method (IFM), fed-batch concentration filtrations and membrane fouling autopsy using two lab-made membranes with different porosity. The full-scale energy consumption was also esti- mated. Overall results suggest that the MMV offers a good fouling control and the process was proven to
be economically attractive. By combining the membrane filtration (15x concentration) with centrifuga- tion to reach a final concentration of 25% w/v, the energy consumption to harvest P. tricornutum and C. vulgaris was, respectively, as low as 0.84 and 0.77 kW h/m 3, corresponding to 1.46 and 1.39 kWh/kg of the harvested biomass.
