Photocatalytic Oxidation of Landfill Leachate Using UV/TiO2
Leachate is a mixture of many kinds of substances such as toxic chemicals, organic and inorganic contaminants, and heavy metals which have been suspended or dissolved. Often, landfill leachate is injected into a deep well. However, the owners of two landfills wanted to see if the leachate could be used rather than disposed.
This presentation, made by Neil Coffman, EI, engineer intern with McKim & Creed at the 2019 Florida Water Resources Conference, describes the results of grant study provided by the Florida Atlantic University Civil, Environmental and Geomatics Engineering department to investigate treatment strategies to make leachate usable.
This presentation shares the results of the bench scale testing activities performed on the leachate(s) and provide insights on the beneficial reuse of leachate treated using photocatalysis treatment using TiO2 and UV. Some of the results of the bench scale testing performed included, but were not limited to:
- The viability of photocatalysis treatment via TiO2 and UV on different strengths of leachates at various TiO2 doses, UV intensities, and treatment times.
- Recovery efficiencies of TiO2 from the treated waters with different recovery technologies.
- Economics of photocatalysis treatment via TiO2 and UV.
