Next-level microalgae production:
Flat-Panel-Airlift Technology
The Flat-Panel-Airlift-Photobioreactors (FPA) from Subitec for microalgae cultivation combine state-of-the-art technology with profound biological insights. Developed by the Fraunhofer Institute, the FPAs provide an optimised growth environment by balancing critical parameters. At the heart of the FPA system is the innovative Airlift technology, which enables continuous circulation in the culture medium. This ensures uniform light and nutrient exposure for the microalgae. Air injected at the bottom of the reactor creates an upward flow in the medium, which is then redirected downwards, maintaining a constant circulation. This circulation not only increases growth rates and biomass yield, but also acts like a gentle mixer. By minimising shear forces that could damage the delicate microalgae cells, the Airlift system avoids cell damage due to strong turbulence.
Efficient gas transfer
Within the system, the airlift technology also improves the efficiency of gas transfer, a critical aspect for microalgal growth. After introducing CO2-enriched air into the system, the airlift mechanism uses small air bubbles to extend the residence time of the carbon dioxide in the culture medium. This extended residence time leads to improved CO2 dissolution, which increases photosynthetic efficiency, and optimises the use of the supplied nutrients.

Optimal illumination for more biomass
FPA-Photobioreactors from Subitec use special LED grow lights on both sides of each plate to provide optimal illumination for microalgae photosynthesis. This prevents self-shading, a common problem in conventional systems, and maximises light utilisation, resulting in higher biomass yields.
Temperature control for versatile cultivation
The FPA systems are equipped with a robust temperature control mechanism. It maintains optimal temperatures for microalgae, reduces thermal stress and supports the growth of a variety of sensitive species.
Closed system for no-compromise purity
FPAs from Subitec have a closed design that protects against contamination. This is crucial for the cultivation of high-value or genetically modified strains and ensures that no harmful substances are released into the environment.
Resource-efficient operation
The FPAs are primarily designed for efficiency and minimise water and energy consumption. The closed system prevents water evaporation, which is crucial in water-scarce regions, and the energy-efficient LED lighting reduces the carbon footprint.Operation
Durable and cost-efficient design
Made from wear-resistant, corrosion-resistant materials, FPA photobioreactors offer long-lasting performance and low maintenance, improving ROI.
Scalable for a wide range of applications
FPAs are modular and can be easily scaled up or down to meet different production needs, from small-scale research to commercial production, without compromising quality.
Advanced control for remote management
The FPAs are equipped with a state-of-the-art control system that enables precise parameter setting and remote control, providing unprecedented operational flexibility.
Simplified harvesting process
The FPA design from Subitec simplifies the harvesting process by concentrating the microalgae at specific points in the system. This not only reduces operational complexity, but also minimises the energy required for harvesting, which further increases system efficiency.
