More Information
Summary:A method for separating dispersed algae from an aqueous system is provided. The method includes adding to the aqueous system a polymer including tannin to form flocculated aggregates, and separating the flocculated aggregates from the aqueous system. A method for pretreating water comprising dispersed algae in an algae biofuel production system is also provided. The method includes adding to the water a polymer including tannin to form flocculated aggregates, and separating the flocculated aggregates from the water.
