A centrifuge uses 48.8% of the total energy consumption during algal biofuel production
Harvesting microalgae is difficult as well as energy intensive. This is mainly because the most rapidly growing algal species are frequently very small and often motile unicells which are the most difficult to harvest. Moreover, the conventional harvesting methods used for harvesting microalgae – such as centrifuges, filtration and flotation equipments – are energy-intensive.
A study claimed that a centrifuge uses 48.8% of the total energy consumption during algal biofuel production. Thus, the major challenge lies in maintaining an effective interaction between the development of cost-efficient harvesting technologies and the selection of algal species for mass culture.
