Effluent treatment and bioremediation by microalgae: experiments and studies

For industrial companies, local authorities, and territorial actors.

Microalgae naturally capture nutrients (nitrogen, phosphorus, minerals...) and carbon during their growth. Under certain culture conditions, microalgae are then able to treat certain liquid and gaseous effluents. After treatment, microalgae can be harvested and valorized, creating a new resource in a circular economy context.

Yes, APESA has a laboratory dedicated to the study of microalgae growth but also to their harvesting and valorization, whether agronomic, energetic, or in molecules of interest after extraction.

Yes. During effluent treatment studies, we can perform a screening of different microalgae and cyanobacteria strains (freshwater and marine) to identify those most suited to the effluent and culture conditions. APESA has some conventional strains in its collection (C. vulgaris, T. Obliquus, A. platensis, etc.) but can also work directly with the client's strains.

Yes. APESA's technical and scientific teams can identify the most efficient and suitable solutions, comparing them with conventional processes and/or other treatment processes via microalgae cultivation.
