| description | Microalgae harvesting methods can currently be classified as mechanical,
chemical, biological and electrical. Centrifugation, flocculation and filtration are among
the top three preferred harvesting techniques to obtain microalgal biomass for
applications such as biofuel, human and animal food, and water quality restoration. The
present study investigated the variables affecting the biomass recovery efficiency via
centrifugation, flocculation and filtration method. Coccomyxa sp. microalgae strain was
locally isolated and cultivated for the investigation and comparison of harvesting
efficiency for each method. Based on the results in this study, a centrifugal speed of
5000 rpm can give rise to harvesting efficiency >95% at 5 minutes. Centrifugation time
at 2 minutes and above was capable of attaining >90% of microalgal biomass recovery
while centrifugation time longer than 5 minutes did not show significant increase in
harvesting efficiency. |
