All around ideally supplied algae

Optimal conditions through holistic liquid analysis

Algae are considered a true allrounder. Among other products, they are used in food supplements, as fuel, and in cosmetics. Due to the numerous, also novel, applications, the demand for the green microalgae is increasing. Jongerius ecoduna in Austria is cultivating the algae on an industrial scale.

Photo-bioreactors to meet the increasing demand of algaes

Results

  • Ensures economiuc efficency in the cultivation of algae

  • Reliable monitoring and support the algae growth in a targeted manner

  • Precise dosing of nutrients such as CO2

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.

Our solution

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.

OUSBT66

Capture optical density
Inline analysis of algae concentration to monitor cell growth and ensure ideal growth conditions.

Monitor CO2 content with Memosens CPS11D ©Endress+Hauser

Memosens CPS11D

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 filtrate with CLS82D ©Endress+Hauser

Memosens CLS82D

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.
