Algae cultivation in flat panel reactors compared to tubular glass PBRs [Free Guide]
Algae can be cultivated in open or closed photobioreactors (PBR). The main difference between these two approaches is whether the algae solution is separated from harmful environmental influences (closed systems) or not (open systems).
Closed PBRs are available in different types. They differentiate by the type of container that the algae should proliferate. The most common types of cultivation are: plastic bags, flat panel reactors and tubular reactors. The containers of flat panel and tubular reactors can be made from different materials: either disposable polymer or sustainable glass.
If planning on cultivating algae in a closed PBR, the use of flat panel reactors initially appears as an interesting approach. In theory, this method offers high light absorption due to the way that it is constructed and results in rapid algae growth. In practice however, numerous influencing factors reduce this advantage.
How a flat panel reactor works
Simply put, a flat panel reactor is built as follows: For a single reactor module, two plastic panels are placed opposite each other and are welded together at all four sides. This allows a small hollow space to be formed between the panels. The algae cultivation solution is filled into this hollow space.
The single modules are installed horizontally. These modules are installed next to one another to form the reactor. The panels of such a reactor can theoretically be made of glass or different plastics. In industrial operation however, only flat panel reactors made of polyvinylchloride (PVC) are used.
During the cultivation phase, it has to be possible to give the algae solution CO2 and nutrients. This is done through hoses that are installed at the bottom of the reactor module. Further hoses at the bottom ensure the algae harvest.
