Electrochemical Pre-Treatment of Wastewater from color Photograph processing unit

摘要

From the studies outlined herein, it is concluded that, electrochemical oxidation of photo-processing wastewater using cast iron electrode results in the removal of COD of wastewater from photo-processing units. Further, an increase in biodegradability is observed due to the electro-Fenton process. Also, in presence of hydrogen peroxide the electrolysis process could be an ideal option for public sewer disposal; but its treatment to meet surface water discharge standards seemed to be non-viable.
