Photobioreactors

GWP®-III

The GWP®-III is variable angle automated GWP® equipped with a pneumatic cylinder that allows tilting and adjustment of the reactor to optimize irradiance at the culture’s surface.
The containment structure is made of stainless steel and allows to maintain an average light path of the culture chamber of about 4 cm. It can be easily opened for quick replacement of the plastic culture chamber. The culture chamber is completely closed to prevent external contamination and to allow exhaust gas collection and recycling. The GWP®-III is equipped with sensors (pH, temperature, PAR light, D.O), gas and water flow-meters, pumps and tanks for continuous dilution, but batch cultivation is also possible. The GWP®-III is PLC controlled and a SCADA software is supplied for data storage, alarms and remote control. Distance between panels can be adjusted in order to simulate different full-scale configurations.

GWP®-II

The GWP®-II is a low-cost photobioreactor suitable for pilot plants and commercial installations.
It can be easily scaled-up from few square meters up to hectares. It’s suitable to fragile microalgae and respect to traditional systems allows higher volumetric productivities and higher biomass quality (lower contamination). Biomass production costs with the GWP®-II are comparable to that of open systems. As for the other GWP® models, the culture chamber can be easily replaced when weathered or damaged. Panels are hydraulically connected and the culture is pump-circulated in order to ensure a more homogenous suspension and a better control of the process. The GWP®-II is PLC controlled and a SCADA software is supplied for data storage, alarms message and remote control.

Open Ponds

In collaboration with RECORD (Firenze, Italy) and Microalgae Camporosso (Imperia, Italy) F&M has developed the innovative pond design: F&M-RWP. The main improvement respect to traditional raceway ponds is the reduction of water depth to about 5 cm that allows to reach higher biomass concentrations and higher volumetric productivities with a significant reduction in harvesting, operation costs and possible contamination.
F&M design customized F&M-RWP up to 1500 m2 and commercializes smaller units (5 – 20 m2) for research purpose. Smaller units are provided with paddle wheel, control systems and are ready to be installed at the clients site.
