Biogas Purification through the use of a Microalgae-Bacterial System in Semi-Industrial High Rate Algal Ponds

Our research focuses on developing sustainable and viable microalgae biotechnology for biomethane obtention. We show with that it was possible to scale the biogas filter up to some industrial scale under other conditions. The process of scaling is aimed at treating larger flows of biogas in smaller facilities with the aim of making it more economically viable.

Additionally, the process seeks to promote operating conditions that can lead to greater production of high value by-products extracted from microalgal biomass. Through a full-scale process exposed to outdoor conditions, we have discovered various species of microalgae that enable us to operate the microalgae filter efficiently. We have also identified the optimal operating conditions that lead to a higher volume concentration of biomethane.
