This study explored the feasibility of direct photolysis using UV LED technology and UV LED based advanced oxidation processes for removing organic matter from wastewater. UV doses of 2500 mJ/cm2 and 5000 mJ/cm2 at a wavelength of 275 nm were used with chemical oxidation concentrations at 1 and 10 mg/L respectively. UV LED alone for BOD removal was also assessed at both bench- and full-scale. The study found that all AOP conditions resulted in significant reductions in BOD compared to the control, however, 10 mg/L concentrations for chlorine achieved a final BOD below current national performance standards. UV LED alone was also found to result in additional BOD removal from plant effluent at both bench- and full-scale. As environmental concerns continue to grow, it is imperative to continue researching and optimizing AOPs for wastewater treatment.enBiological Oxygen DemandAdvanced Oxidation ProcessWastewater TreatmentUV LEDSoluble Biological Oxygen DemandThesis
