Laminar photobioreactor for the production of algal biomass on a large scale
PBR-L is a photobioreactor for concentrated microalgae biomass production, based on the technique of immobilized cells and specially designed for CO2 capture and removal of nitrogen and phosphorus (eutrophication elements) in effluents from sewage treatment. It has been developed by the Agro-Energy Group of the Technical University of Madrid (UPM, Spain) and patented by UPM.
The algal biomass produced can be used for fish farming as a source of fat and protein for fish nutrition. It can also be used as a raw material of biofuels (biodiesel, bioethanol, bio-kerosene, methane).
The PBR-L is designed for removing eutrophication elements in wastewater -mainly phosphorus and nitrogen- and for the capture of CO2 and other flue gases from industry and transport.
In addition to the reduction and removal of these pollutants, abundant algal biomass with a number of uses and both feed and industrial applications, is produced.
Versus other present photobioreactors, PBR-L has the advantage of lower production costs and reduced energy consumption in algal biomass harvesting.
PBR-L has a modular design and easy installation, applicable to both small and large scale.
“PBR-L contributes to clean the environment while microalgal biomass is obtained simultaneously, potentially used as a raw material for the production of animal feed and biofuels”
“The need of reducing air pollution caused by greenhouse gas emissions and contaminating effluents from wastewater treatments is a problem of growing interest worldwide”
