Research on the electrocoagulation (EC) of hexane extractable materials (HEM) has been conducted at the University of New Orleans using a commercial bench-scale EC reactor. A series of EC experiments were performed using a synthetic emulsion with a HEM concentration of approximately 700 mg/L−1. It was confirmed that EC of HEM follows first-order kinetics, and kinetic constants of 0.0441 s−1 and 0.0443 s−1 were obtained from applying both the dispersion and tanks-in-series (TIS) models, respectively. In both cases, R2 was 0.97. Also, the TIS model indicated that each cell of the EC behaves as an independent continuous-stirred tank reactor.
