The current study investigates the influence of the current density (CD) and electrodes gap (EG) on the removal of reactive red 120 dye (RR-120) from drinking water using electrocoagulation (EC) process. The influence of CD was studied by treating the dyed water at three different CDs (2, 4 and 6 mA/cm2). While the influence of EG was investigated at three EGs (5, 10, and 15 mm). The Results obtained showed that increasing the CD enhanced the removal of the dye. However, increasing the EG significantly decreased the dye removal efficiency. It was found that dye removal increased from 87% to 98%, as the CD increased from 2 to 6 mA/cm2, respectively. While increasing the EG from 5 to 15 mm decreased the dye removal from 96% to 80%, respectively.
