Full Description

This slide presentation outlines a bench-scale study of 2-Methylisoborneol (MIB) control by ozone at the City of Houston Northeast Water Purification Plant (NEWPP), a conventional surface water treatment plant. Project goals included: evaluate ozone as an oxidant for MIB removal at theNEWPP;compare the treatment efficiency of using ozone toremove MIB from raw water vs. settled water; and,investigate the impacts of ozonation on water quality. The testing approach included:sample water spiked with various MIBconcentrations;raw water sample - 10, 50, and 100 ppt;settled water sample - 10, 30, and 50 ppt;Ozone Dose - 1, 2, 3, and 4 mg/L; and,Reaction Time - 15 minutes. A summary of the study includes these points:ozone is an effective oxidant for MIB removal, theremoval efficiency is dependent of the initial MIBconcentration in the water;ozonation is more effective for removing MIB fromsettled water than raw water;TOC and DOC were also removed by ozonation, yetthe removal percentage is not significant; and, additionally, ozonation reduced UV absorbance. Includes figures.
