文摘

Microalgae are promising feed stock for biofuels but harvesting is a major hurdle. PDADMAC, used for water treatment, can be used for sedimentation of such algae. This polymer was effective at 5 mg/L, with fast kinetics and stable sedimentation over wide pH range. Achieving zeroing of Zeta potential is not needed for effective sedimentation. This flocculant could be used for effective low-cost microalgae flocculation.
