摘要

The objective of this work is to study the efficiency of electroflotation process by treatment of effluent from vegetable oil refining industry in the form of oil-water emulsion. We will interest in hydrodynamic aspects in electroflotation columns. We will study the effect of current density and oil concentration on bubbles diameter, bubbles rise velocity, Reynolds number and the effect of the latter on the efficiency of the oil recovery. To evaluate bubble's characteristics we used the method of video recording followed by an image processing, view of its simplicity this method is used widely. The different bubbles flow regimes were predicted by the calculation of Reynolds number. The efficiency of the process was estimated from turbidity.
