Harvesting microalgae by bio-flocculation and autoflocculation

Research output: Thesisinternal PhD, WU

Abstract

Harvesting in commercial microalgae production plants is generally done by centrifugation, but this requires upto about 50% of the total energy gained from the microalgae. The energy needed for harvesting can be reduced considerably by pre-concentration of the microalgae prior to further dewatering. The focus of this thesis was on development of a controlled pre-concentration step in which bio-flocculation and autoflocculation using oleaginous microalgae is applied combined with gravity sedimentation. This technology was evaluated in terms of energy demand for harvesting microalgae.
