METHOD AND DEVICE FOR THE PRODUCTION OF MICROALGAE BIOMASS
20220389357 · 2022-12-08 ·

The invention relates to the production of microalgae biomass. The microalgae contained in a suspension of water and microalgae are continuously phototrophically or mixotrophically cultivated in a cultivation module (1), which is passed multiple times by the suspension and has a gas part and a liquid part with a liquid supply (3), by supplying light from at least one artificial light source (5) and nutrients. According to the turbidity established by sensors, volume fractions of the suspension are repeatedly discharged from the cultivation module (1) for the harvest of microalgae and removed by means of a centrifuge (7). The cultivation of the microalgae occurs in an climate chamber forming the cultivation module (1), which is operated using water. Alongside a regulating of the temperature of the suspension, there also occurs a regulating of its pH value via the controlled addition of buffer ions and a regulating of the redox potential of the suspension and thereby also of its microbial contamination by controlling the light and nutrient supply, as well of a metered addition of oxygen. In addition, after the removal of microalgae, the remaining suspension is irradiated with UV light in order to kill unwanted microbial contamination before being returned into the cultivation module (1).
