Abstract

Introduction: Production and processing of raisin varies in different areas and is based on weather conditions and technological devices of each region. Therefore, generated WASTEWATERs are very changeable in terms of quantity and quality. The objective of this study, thus, was to investigate the efficiency of the electrochemical process, which is an environmentally benign and simple technique, in the effluent of a RAISIN CLEANING FACTORY.Methods: The present experimental study was conducted, at a laboratory scale, in a reactor with an effective liquid volume of 80 ml. WASTEWATER from a RAISIN CLEANING FACTORY was treated by using lead dioxide electrodes during an ELECTRO-OXIDATION. In order to determine the efficiency of this process in organic materials removal, chemical oxygen demand (COD) of the samples was measured before and after of each run. Moreover, the effects of parameters such as pH, current density, and reaction time were studied and consumed electrical power was calculated.Results: It was found that, by this method, 86% of COD was removed at the following conditions: pH 3, current density 40 mA/cm2 and reaction time 360 min in a way that the efficiency went up with increasing both time and current density. Furthermore, at optimum conditions, the amount of electrical energy consumption was 5.4 kW/h COD.Conclusion: Considering the high loading rate of the studied WASTEWATER, despite having high efficiency, this system can only be applied as a pretreatment step and the effluent from this process requires further treatment to meet the environmental standards.
