Harvesting Microalgae

As a source of renewable energy and dietary supplements, microalgae emerged as a promising source. In the last few decades, with a wide range of commercial applications algae have attracted a lot of attention of the researchers. However, microalgae utilization is not economically sustainable due to the high cost of harvesting. But many biotech firms are engaged in developing the cost-effective technique of Harvesting Microalgae with nonportable land and seawater. Harvesting of microalgae is an important part of the cultivation system to produce higher biomass.  The purpose of harvesting is to obtain microalgae slurry. There are many techniques available, but coagulation and flocculation, centrifugation and filtration were found to be most suitable for considered applications.
