All around ideally supplied algae

Algae also occur in nature, but the company Jongerius ecoduna has specialized in the industrial production of the eukaryotes. The algae are cultivated in glass columns around six meters high. To achieve maximum product yield, various quality parameters are monitored. In addition to the pH value, this also includes conductivity as well as optical density. This measurements need to be reliable and require a lot of know-how.

With the solution from Endress+Hauser algae cultivation can be made even more effective and profitable. Different parameters of the liquid analysis are measured in different process steps. With the help of the sensors OUSBT66, CPS11D and CLS82D as well as the transmitter CM44P, them emerging challenges around the optimal growth and supply of the algae are mastered.

Monitor CO₂ content
pH measurement to draw conclusions about the CO₂ content in the algae suspension and thus ensure optimal supply of the algae.

Processing of the filtrate
In cross-flow filtration for harvesting algae, conductivity is used as a parameter to monitor the amount of the water in the filtrate that is returned to the process.
