Abstract
Research on new sources of bioenergy is nowadays driving attention to microalgae. Cost-effective biomass harvesting and thickening pose a challenge for massive microalgae production for biofuels. In this study, coagulation-flocculation and sedimentation with natural flocculants (Ecotan and Tanfloc) was evaluated on microalgae grown in an experimental high rate algal pond treating urban wastewater. Jar tests showed how flocculant doses of 10 and 50mg/L of Ecotan and Tanfloc enabled over 90% bioma...
