''método e aparato para fornecer um fotobiorreator''

摘要

The present invention provides for a photobioreactor for the cultivation of photosynthetic microorganisms and comprises a hydraulic circuit through which an aqueous solution containing culture of at least one type of photosynthetic organism circulates and gets exposed to a light source. The photobioreactor also comprises a means for feeding carbon dioxide into the system, a means for oxygen degasification, and a means for injecting nutrients into the system. The hydraulic circuit is comprised of two open receiving channels at the same relative elevation, a set of transparent or translucent tubes which connect receiving channels to each other, and at least one fluid moving device to move the fluid from the first to the second receiving channels through the tubes. Each receiving channel also comprises a directional dam which assists in maintaining two different surface levels of the aqueous solution within the upstream and downstream portions of each receiving channel.
