ABSTRACT
In this work, the hydrodynamic effects of rotating disk filtration (with maximum shear rates of 16,000â¯s-1 and 66,000â¯s-1) were evaluated and compared with the crossflow filtration (16,000â¯s-1) in the recovery of lipids from a model solution that simulates the characteristics of Parachlorella kessleri aqueous extracts. Four polymeric membranes were tested. The PAN 500â¯kDa membrane along with the rotating disk filtration presented the best performances for lipid concentration and coalescence. The rotating disk filtration was tested with real microalgae extracts, confirming the total lipid retention and the limited membrane fouling.
