The global objective of this work was to evaluate the integration of gas-solid ultraviolet (UV) photocatalytic oxidation (PCO) downstream of an air stripper as a technology for cost-effectively treating water pumped from an aquifer contaminated with chlorinated volatile organic compounds (VOCs). Experimental work was performed at the bench-scale in the laboratory during the first phase of the project, and at the pilot-scale in a simulated field-test situation during the second phase.
