Water Treatment and Advanced Oxidation Technologies Laboratory

Director: Dr. Dionysios D. Dionysiou
Location: 781 Engineering Research Center

  • Drinking water quality, supply, treatment and purification,
  • Wastewater and industrial wastewater treatment using physical/chemical processes,
  • Transition metal catalysis,
  • TiO2 photocatalysis, UV-enhanced technologies, Fenton's and Photo-Fenton's hydroxyl-radical based processes,
  • Other radical-based (i.e., superoxide, sulfate) destructive chemical oxidation technologies, and
