3 Cultivation of Microalgae
Microalgae can be nurtured by familiar practices like open-pond raceway system and
closed photobioreactor system.
3.1 Open Ponds
These systems are accepted for being simple, easy to manage, and inexpensive (low
capital and control costs). They can be effortlessly clean up subsequent to cultivation
[13], and less process control is required. They are effective systems for lower value
products with large markets. Raceway ponds (Fig. 3a), spherical ponds tanks,
shallow large length ponds, and closed ponds are presently used in industrial
research.
