To enhance the biodegradability of diethylenetriaminepentaacetic acid (DTPA), effluents containing this chelating agent were electrochemically treated. Electrochemical pretreatment effectively fragmented DTPA into biodegradable compounds as demonstrated by increased BOD/ThOD ratios. The presence of other organic compounds reduced the rate of electrochemical DTPA degradation, but less than proportionally, indicating that DTPA degradation is partially selective. Finally, an experiment was performed to assess removal of DTPA under the conditions of an activated sludge plant treating pulp and paper effluent. The combined electrochemical and biological treatment resulted in an overall removal of 70% of DTPA nitrogen. The combined processes degraded more than 95% of the DTPA.
