I am seeking your advice regarding the use of a 50L photosynthesis reactor for wastewater treatment. I intend to supply pure CO2 but am uncertain about the appropriate CO2 flow rate (L/min) for the reactor. How to determine this value based on reactor volume?
If you have any references or recommendations, please provide the titles. Your guidance would be greatly appreciated!
Thank you very much!

To determine the appropriate CO2 flow rate (in L/min) for your 50L photosynthesis reactor used for wastewater treatment, you'll need to consider a few factors:
It's important to note that the actual CO2 flow rate may vary based on experimental conditions, the specific setup of your reactor (e.g., mixing efficiency), and the growth characteristics of the organisms you are cultivating. Therefore, initial estimations may need to be refined through practical experimentation and monitoring within your specific setup.
Photosynthesis uses carbon dioxide and water to produce sugars from which other organic compounds can be constructed, and oxygen is produced as a by-product. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
1. Uptake of CO2 can be measured with the means of an IRGA (Infra-Red Gas Analyzer) which can compare the CO2concentration in gas passing into a chamber surrounding a leaf/plant and the CO2leaving the chamber.
2. It can be determining through the use of the chemical indicator; phenol red. Phenol red is a pH indicator that changes color from red to yellow in the presence of carbon dioxide.
3. The chemical sodium hydroxide is placed in the bag with the plant to absorb the carbon dioxide. The plant is left for 24 hours and the leaves are tested for starch using iodine. The leaves will show that no starch has been made as no photosynthesis occurred without carbon dioxide.
