Abstract

Described herein are systems, methods, and apparatuses for aggregating microorganism in an aqueous suspension. In particular, are systems, methods, and apparatuses that apply an electrical field and/or acoustic energy to an aqueous suspension comprising microorganisms as the aqueous suspension follows a flow path to cause aggregation of the microorganisms. The electrical field may be continuous or pulsed. In some embodiments, the flow path for the aqueous suspension may vary.
