Abstract:

Electrochemical treatment of wastewater generated from the production of chemicals such as insecticide, herbicide, and pesticide was investigated. IrO2/SnO2 film electrode prepared on titanium was used as an anode in the electrochemical reactor. Stainless steal was used as a cathode. Batch tests were conducted to investigate IrO2/SnO2/Ti as an alternative electrode material for anodic oxidation of recalcitrant compounds present in the wastewater. Organics in the wastewater were degraded and mineralized by the electrochemical oxidation. The degradation rate increased with an increase in imposed current density. Pilot test was conducted to test if the anode can withstand high potential combined with aggressive chemical conditions (elevated acidity of medium, chlorine, etc). It lasted for more than 6 months with high TOC removal efficiency
