Abstract
This study was conducted to assess the performance of the electro-coagulation and electrolytic plant currently used in treatment of petrochemical effluents produced in petrochemical plant in the Niger-delta Nigeria. Data used in this study is the daily data of the petrochemical effluent at the inlet and outlet of the electro-coagulation and electrolytic treatment plant collected within the duration of six month (February to July 2023) and contain information on eight physicochemical properties of the effluents, namely: pH, Chemical Oxygen Demand (COD), Oil & Gas content (O&G), Total Suspended Solid (TSS), Total Dissolved Solid (TDS), Benzene-toluene-xylene content (BTX), turbidity and conductivity. The data of these physicochemical properties of the raw and treated effluent were evaluated on monthly averages and compared with National Environmental Regulation (NER) and World Health Organization (WHO) standards. The monthly-based performance of the treatment plant was also evaluated based on its ability to improve the physicochemical properties of the effluent. Descriptive statistics and T-test were used for the data analysis. The results showed that the physicochemical properties of the raw effluent were not within recommended standard while that of the treated effluent were within recommended standard except for pH (pH = 6.22, NER = 6.0 – 9.0, WHO= 6.5-8.5). The results showed that there is a significance difference between the physicochemical properties of the raw and treated effluents except for pH at 0.05 significance level, the results also revealed that the performance of the electro-coagulation and electrolytic treatment system is substantially high with respect to the treatment of the individual physicochemical properties of the effluents as follows: COD is 71.07%, Oil & Grease =79.38%, BTX =96.01%, TSS=75.08%, TDS=636%, Turbidity=76.3%, Conductivity =1200%. It was therefore concluded, among others, that electro-coagulation and electrolytic treatment system is suitable for treatment of petrochemical effluent. It was also recommended that designers of the petrochemical plant should improve its operations in a way that reduce the number of pollutants in their effluent
