| Wastewater can be a potential source of fresh water by using waste minimization and treatment technologies. Considering this issue, produced water (PW) and truck wash water (TWW) was treated with the cheapest wastewater treatment technique electrocoagulation (EC). Produced water (PW) is salty water trapped in the reservoir rock and brought up along with oil or gas during production. It subsists under high pressures and temperatures, and usually contains hydrocarbons and metals. Therefore, it must be treated before being discharged to surface water. Different techniques are being used to treat PW through phase separations, system control and design, and chemical treatments. In this study, we discuss our experimental results on treating PW through electrocoagulation (EC). With increasing globalization set-up and advances in road transport system, the use and number of heavy duty vehicles, such as trucks, has increased for transportation purposes. The wastewater generated due to truck washing has also escalated. The performance of EC treatment of PW and TWW was investigated for the reduction of chemical oxygen demand (COD) and metal ions. Effects of different electrodes, residence time, current density, and pH were also studied to optimize the treatment conditions. The floc that was produced during these treatments was characterized using XRD, SEM/EDS, and FTIR. |
