Abstract

Electrocoagulation is electrochemical water and wastewater treatment technology which is the simplest technology using an electrochemical cell where the supply of DC power is applied to the electrodes, made of aluminum metals, and the electrolyte is oily bilge water. The electrocoagulation of oily bilge water was experimentally conducted in a batch system. Aluminum plates with dimensions of 20 cm ×8 cm × 0.2 cm were used for electrodes and mounted vertically with a distance of 4 cm. These electrodes were then connected to the direct current power supply of 10 V and 10 A. The total area of the effective working plate was 160 cm2 when immersed at a depth of 10 cm to the solutions. The results showed that total dissolved Solids (TDS) decreased from 31.2 to 7.54 mg/l and formation of sludge increased up to 12.54 g/l with oil concentration of 50 g/l for 15 min. The largest oil removal of 99.5% was obtained using the initial oil concentration of 55 g/l and the lowest of 96.25% was obtained with the initial oil concentration of 146.04 g/l. A current density of 62.3 mA/cm2 was achieved for a maximum oil removal.
