Abstract

The influence of the applied electrical current and time of electrocoagulation on efficiency of the separation process of a mineral oil in water emulsion was investigated by measuring the total organic carbon, volume of filtrate, mass of separated oil phase, as well ass the aluminum electrodes consumption. Results demonstrated a high efficiency of hydrocarbons’ removal form water emulsion, more than 96%, expressed relative to the total organic carbon in water and for all applied currents. Water effluent was clear, without color and odor. The current efficiency increases with the increasing solution electrical conductivity and decreasing current density. Electrocoagulation has shown as a very fast method; time required for a complete separation of emulsion was 50 min for the current of 0.1 A and less than 10 min for the current of 1.0 A.

Keywords
