Description:

This paper reviews anerobic bio-oxidation processes and presents the results from two bench scale design studies: one evaluationg the degradation of MTBE and its daughter product tert-butyl alchohol (TBA); and the second the degradation of a mixture of DCA and benzene. The bio-oxidation systems evaluated in a banchscale study included oxygen, nitrate, ferric chloride (for ferric iron alone), ferric sulfate (with both constituents potential electron acceptors), potassium sulfate (for sulfate alone), and humate-catalyzed ferric chloride and ferric sulfate. The MTBE and benzene were rapidly degraded by oxygen. MTBE is degraded by humate-catalyzed ferric iron almost as rapidly as with oxygen, however TBA the MTBE daughter product was not degraded. Ferric chloride alone degraded MTBE and TBA completely at a rate about 20% that of oxygen. Ferric sulfate, and sulfate also slowly degraded MTBE. The nitrate was completely ineffective. In the case of benzene and DCA, the humate-catalyzed ferric chloride is as effective as oxygen for benzene, and is also degrading the DCA. The oxygen did not stimulate DCA degradation. Nitrate, ferric sulfate, sulfate, and ferric chloride without the humate catalyst were ineffective for benzene and DCA.
