Abstract
Wastewater of alkyd resin production (ARW) has low pH value (2.3) and high organic matters (15,304 mg/L of TOC and 45,220 mg/L of COD) as well as is toxic and non-biodegradable. In addition to, it does not respond to chemical coagulation and adsorption. Thus, advance oxidation processes (AOPs) or combinations of AOPs are very important alternatives for treatment of ARW due to the advantages which they have. The purpose of this study is to investigate the treatment efficiencies of anodic electrooxidation process by boren doped diamond electrode (BDD). The effect of process parameters such as current density (40-100 mA/cm2), operation time (0-180 min.) and pH of wastewater were investigated. The maximum removal efficiencies were obtained as 42.3 % of TOC and 43.4 % of COD at the 100 mA/cm2, 180 min and pH of 3.5. The consumed electric energy and operation cost were calculated as 169.07 kWh/m3 and 42.27 TL. Although as the removal ratios were not seemed very high, the removed COD and TOC values showed the potential of EO with BDD. Consequently, EO was a suitable process for the treatment of ARW; however the results showed that it must be applied with combination of other AOPs.
