What is BIORAT?

BIORAT is a life support experiment aimed at providing a reliable and complete life support sub system including gas regeneration, water recycling, food production and waste management.

The objectives of BIORAT:

  • Demonstration of a closed CO2/O2 cycle.
  • Validation of the predictive control approach and the associated modelling.
  • Characterisation of specific parameters and control variables like gas transfer and light energy.

What happens in the BIORAT Photo Bioreactor?

  • Growth of Spirulina platensis, Fixation of CO2.
  • Generation of edible biomass, Regeneration of O2 for respiration.
  • Exchange of nutrients and metabolic gasses between the cell surface and the medium.

Future BIORAT Developments and Conclusions:

  • Different Types of Consumer
  • PBR size (depending on O2 needs)
  • Consumer Compartment
  • Harvesting
  • pH control or QpQr control
  • MELiSSA: Study of light transfer in PBR (growth, activity of algae
  • BIORAT: Demonstration of this knowledge by a photo bioreactor, a consumer compartment and related control technology and software.
    • Accuracy of the control
    • Promising possibilities of losed loop gas exchange systems
