WASTEWATER TREATMENT BY ELECTRO‐OXIDATION PROCESS WITH TiO2

The environment of wastewater containing toxic organic compounds by the industrial community has the environment of wastewater containing toxic organic compounds by the industrial community has increased significantly in the recent past. So, the treatment of such wastes generated from the industries is considered necessary. Untreated wastewater, if allowed to accumulate will result in the decomposition of organic material that leads to the production of toxic gases. For wastewater, the objective is to remove or reduce the concentration of organic and inorganic compounds. Some of the constituents and compounds present in wastewater lead to serious problem to the environment. This study presents the treatment of petroleum wastewater using nano scale TiO2 in the presence of electro‐oxidation process. TiO2 physiochemical characterization of sol‐gel method analyzed using Ultraviolet light (which is an electromagnetic radiation), Scanning Electron Microgram (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and X‐ray Diffraction (XRD). The influence of TiO2 dosage and initial pH on % COD reduction was studied. The results indicated that using TiO2 in combination with electrocoagulation at a dosage of 0.15 g/l and a pH 10 in Current Density (CD) respectively is an efficient method for the treatment of petroleum wastewater
