A4F products

Tubular Photobioreactors are one of the most used technologies for microalgae production in closed systems.

This closed photobioreactors offer a solution to improve contamination control and achieve higher volumetric productivities. Within closed systems, the most versatile and economic system for the cultivation of microalgae is the flat panel PBR constituted by a disposable transparent LDPE film enclosed within a metal frame.

Higher biomass densities. Higher biomass productivities. Lower biomass production costs. Lower harvesting costs. Better replicability and scalability.

Continuous design optimization since 2010 by A4F for cost effective microalgae production considering energetic costs, productivity enhancement and weather specific conditions, such as high rainfall or sand storms.

Prefabricated algae ponds that include containment walls, liner, paddle wheels, and optional control systems. Ideal for microalgae that grow in selective media and to install in areas without large climate variations or frequent storms. Over decades the most common design used for industrial deployment or large areas (over 10 ha up to 100 ha). Typical industrial production modules are 5.000 m2 and 1.500 m3. Recommended for wastewater treatment applications.
