The objective of this project was to study and evaluate the treatment efficiency of a reactor that utilized titanium dioxide (TiO2) nanoparticles immobilized on glass beads in both a fixed and fluidized bed configuration. The degradation of the organic contaminant, methylene blue (MB), was evaluated with a UV-vis spectrophotometer. Results suggested that the inter-particle forces acting between coated glass beads in a fluidized bed exceeded the bond strength of the nanopowder coating and thus detached. Conversely in a fixed bed, with a lower fluid flow rate, results showed a steady reduction in MB concentration over time when the immobilized TiO2 was exposed to UV irradiation. This degradation was found to perform at a rate much higher than the rate of UV exposure without TiO2 present.
