TREATMENT OF MTBE - CONTAMINATED WATER USING THE FENTON'S REAGENT: EFFECTS OF SINGLE AND MULTIPLE ADDITION OF REAGENT ON THE OVERALL REACTION EFFICIENCY. Presented at 74th Annual Water Environment Federation Conference and Exposition, Atlanta, GA, 10/13-17/01.
Description:
In 1997 EPA issued a "Drinking Water Advisory" for MTBE recommending concentration limits of 20-40 ug/L to avoid taste and odor problems. Further regulations classified MTBE in the list of "potential human carcinogens" in 2000. Therefore, intensive research efforts are currently in progress to find an efficient way for remediating groundwate and surface waters contaminated with MTBE. In a previous laboratory study, we demonstrated the feasibility of MTBE degradation by hydroxyl radicals generated by Fenton's Reagent. System pH and reagent concentration were established as prime control parameters. In this follow-up work, modifications of the method of FR addition are investigated to elucidate the influence of additional parameters on the efficiency of the reaction.
