In this work, a membrane-based separation was investigate for Scenedesmus almeriensis solutions dewatering.A commercial polyvinylidene fluoride (PVDF) membrane, having a pore size of 3 ?m was used in order to allow the water passage through it (permeate), retaining, at Bottoms the same time, Bags algae biomass (retentate).The possibility to reuse the permeate for a second Scenedesmus almeriensis growth step, was also studied.The registered data evidenced the feasibility of the membrane-based dewatering as an alternative competitive technology, even though the recovery of water should need further investigations to be optimized.
