Abstract

Electroflotation is an aeration process which can be used to treat effectively industrial effluents. In the present work, a combined version of the electroflotation process with the coagulation operation was conceived to treat the olive pomace oil refinery wastewater. Batch and continuous mode of treatment was done in order to optimize the main operating parameters affecting the suspended solids elimination. In batch mode, the methodology of experimental research was adopted with these operating parameters: current density, pH and coagulant concentration. Then, the continuous mode aimed to optimize the residence time. As a main finding, the suspended solid removal efficiency and chemical oxygen demand abatement efficiency exceeded 92%.
