The Flat-Panel-Airlift
Photobioreactor (FPA)
Subitec‘s cultivation technology is based upon a specially
shaped and cost-effective plate reactor. The patented and
uniquely designed photobioreactor induces a circular flow
of the suspension by aerating with air/CO2, continuously
moving algal cells trough zones of diverse light intensity.
The technological advancement leads to a wide range of
advantages:
› Optimized light supply for decisively improved growth
› Straightforward and inexpensive operation
› High flexibility by modular design
› Cultivation of a variety of microalgal and
cyanobacterial genera
› Efficient application of artificial lighting possible
COST-SAVING BIOMASS PRODUCTION BY
HIGH PRODUCTIVITY
› Excellent light supply to all cells
› Complete uniform mixing
› Efficient gas exchange
› Minimal shear stress on cells
› High biomass concentrations
› Minor biofilm formation
› Simple temperature and pH control
› Very low power consumption

SUBITEC–15 YEARS OF
KNOW HOW IN MICROALGAE
CULTIVATION SYSTEMS
Subitec was established in the year 2000 by the Fraunhofer
Insitute in Germany. Based on the patented Flat Panel
Airlift (FPA) photobioreactor, Subitec offers systems for
the efficient cultivation of microalgae. This technology
allows customers from research and industry to produce
cost-efficient microalgae biomass in high quality.
Applications range from nutritional supplements over
cosmetics to aquaculture, feed and food as well as to the
chemistry and energy industry.
Based on three sizes (6, 28, 180liter) of the patented
FPA reactor Subitec has marketed laboratory units, pilot
facilities, scale-up and large scale production plants–up
to a volume of 130000liter (34000gallons) and surface
area of 4000m2
(1acre).
