Abstract
The invention discloses a photobioreactor featuring a microalgae cultivation chamber in the form of a closed flat duct irradiated by sunlight. The flat duct is constructed from an inflatable sleeve made of transparent polymer film. This inflatable sleeve is sandwiched between a bank of frames with wire nettings, plates of foamed plastic, a variable air pressure mattress located underneath the inflatable sleeve, and a thermo-insulating transparent inflatable mattress and glass panes above. The variable air pressure mattress facilitates mixing of the microalgae suspension with the gaseous medium containing carbon dioxide and regulates the temperature of the microalgae suspension in the flat duct.
