European Biomass Industry Association EU BC&E, 25 june 2014, Hamburg, Germany Conventional PBR TechnologiesALGADISK - Innovative design Expensive maintenance required (unexpected biofilm formation, pumping systems, sterilization) Low operation cost and easy maintenance. Easy construction procedure. Low CO 2 efficiency (bubbling through the liquid phase) Increase in CO 2 capture efficiency (buffer tank mixing) High water required (raceway ponds, PBR)Low water required Harvesting is difficult, time consuming and inefficient (High Costs) Automatic and continuous harvesting Scale-up problemsEasy scalability trivial Difficult to design at flexible scaleModulable units. Competitive at small scale High land use footprintlow footprint - 20g/mq day of dry algae WHY ALGADISK?

European Biomass Industry Association EU BC&E, 25 june 2014, Hamburg, Germany WP2 - Alga selection and development optimal growth conditions for the selected algae (to be controlled) developing low cost method for measuring thickness of alga biofilm development of biofilm harvesting regulation comparison and set-up WP3 - Disk surface development and characterization, Airbrushing for large scale production Prototype installation and field test WP4 - Design of supporting energy system and accessories Energy consumption, logistic, pumps & pipeline, control system,...
