【 摘 要 】

Electrocoagulation is electrochemical water and wastewater treatment technology that is the easiest technology using an electrochemical cell supplied by DC power to the electrodes. The application of the electrocoagulation process was purposed to treat oily bilge water. The results indicated that the oil removal efficiency was achieved approximately 99.62% at an initial oil concentration of 60 g/l in batch processes. The current density of 62.5 mA/cm2 applied the process produced oil removal efficiency of 99.95%.In a continuous mode with the initial water only present in the reactor, the oil removal efficiency was achieved approximately 100% with a hydraulic residence time (HRT-1) of 6 h for 60 min of operations. However, the initial oil/water emulsion at a concentration of 63.89 g/l present in the reactor, the oil removal efficiency was approximately 73.33% with HRT-1 of 6 h for 90 h of operations.
