Resumen de: WO2024094905A1
The present invention relates to a floating photobioreactor with an oval spheroidal shape, which is designed for the cultivation of microalgae in aquatic media. The photobioreactor is subdivided into two main bodies, namely an upper semispheroid (2) and a lower semispheroid (1). The photobioreactor comprises conventional means for the joining and leaktightness thereof, further comprising gas exchangers, as well as a solar lamp. The inner surface of the lower semispheroid is highly reflective and this semispheroid is provided with thermally insulating means in the form of a removable cover. Its rigid but hydrodynamic design enables better use of wave energy for fluid mixing and renewal, thereby lowering the energy and economic costs and environmental impact associated with the cultivation of microalgae.
