Abstract (en)

[origin: WO9623865A1] A process for carrying out on an industrial level the cultivation of microalgae is implemented in a hydraulic closed circuit: by causing a liquid containing the algae to circulate; by keeping thetemperature of the liquid between two preset values; by introducing into the liquid the amounts of carbon dioxide and nutrients necessary for the algae's metabolism; by exposing the circulating liquid to the sun's rays in a specific transparent part of the closed circuit, so as to allow the algae to conduct chlorophyllic photosynthesis; by extracting the oxygen that is produced during the course of said process; by periodically separating from the circulating liquid the algae that are produced; finally, by extracting said algae from said hydraulic closed circuit.
