Scenedesmus Almeriensis Solutions Dewatering by Using Pvdf

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 the same time, 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.
