Webinar Recording: Microalgae Production in Raceway Reactors

Although engineers have improved the design and operation of the raceway reactors, scaling up and optimising algae productivity and production costs remain challenging. Advanced control strategies can help improve microalgae production. Such strategies must take into account all the major factors that influence the behaviour of the cultures in the raceway. These factors include light, temperature, nutrient concentration, pH and dissolved oxygen.

Models based on the understanding of how these conditions modify the microalgae culture can help to better control production facilities. For instance, simultaneous control of pH and dissolved oxygen can increase biomass productivity by up to 20%.

In outdoor cultivation, monitoring temperature and light is crucial, as they change daily throughout different seasons and affect the culture on a daily basis.
