Sustainable Solutions Laboratory

The Sustainable Solutions Lab focuses on drinking water quality, supply, treatment, and purification. This includes wastewater and industrial wastewater treatment using physical/chemical processes. Other areas of study include:

  • 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
  • Membrane processes for drinking water, wastewater, and industrial water purification.

The laboratory is equipped with various technologies for the treatment and purification of water. Equipment includes:

  • Novel UV/TiO2 suspension-type and immobilized-type photocatalytic reactors for water treatment
  • UV and UV/H2O2 flow through photoreactors for water treatment and disinfection (Trojan UVLogic)
  • Transition metal-based reactors for water treatment
  • Reactors for dark and UV-enhanced oxidation of organics using the Fenton's reaction
  • Reverse osmosis systems
  • Membrane systems for studying the effect of fouling and biofouling in membrane processes for water purification
  • Typical instrumentation and devices for determining drinking water quality and UV radiation properties.
