The unit of Solar Treatment of Water (TSA in its Spanish acronym) was born in 2012, from the Environmental Applications of Solar Energy unit, as a consequence of the strategic plan of CIEMAT to encourage the research activities and applications of solar photochemistry carried out at Plataforma Solar de Almería. The main objective of this research is the use of solar energy for promoting photochemical processes in water at ambient temperature for treatment and purification applications. Research activities are focused on:

  • Heterogeneous  and homogeneous (photo-Fenton) photocatalysis
  • Solar disinfection
  • Other water advanced processes: ozone, UV/H2O2, electrooxidation, membranes, biotreatment.

The main objective of the Research Unit is to apply this research in:

  • Photocatalysts evaluation
  • Industrial wastewater treatment
  • Microcontaminants elimination
  • Water Potabilization and disinfection
  • Hydrogen production.
  • Wastewater reuse in agriculture

TSA unit collaborates in national and international projects, valorizing the research via different goals:

  • Patents.
  • Communication of results in international journal with high IF
  • Formation of researchers by PhD Thesis.
  • Transfer of results to private sector by studies of viability and research contracts.
