Desalination and Photosynthesis
Description and lines of research
The Desalination and Photosynthesis unit develops two parallel lines of work: desalination and water treatment using membrane systems (membrane distillation and solar-powered reverse osmosis), and the production of microalgae and products of interest through solar biorefineries (SABANA Platform).

Strategic lines
- Development of solar desalination and membrane-based water treatment systems
- Application of solar energy to the treatment of hypersaline solutions
- Recovery of valuable compounds from brines and hypersaline effluents
- Design of photobioreactors and novel devices of interest for microalgae cultivation
- Applications of microalgae in the treatment of urban and industrial wastewater
- Valorization of microalgal biomass following sustainable processes based on the biorefinery concept
