Electroflotation of emulsified oilin industrial wastes evaluated with a full factorial design

The use of electroflotation in emulsified oil wastes was studied. A rectangular electroflotation cell was designed and constructed in acrylic with stainless steel cathode and DSA (R) anode with a nominal composition of Ti/Ru0.34Ti0.03O2. The variables studied in the present work were current density and oil, flocculant and electrolyte (NaCl) concentrations. The experiment were carried out in accordance with 24 full factorial experimental designs with two center points. The STATISTICA 5.5 software was used for calculations in order to relate experimental data to a statistical model. The best results, yielded 99.71% oil removal were obtained from 1050ppm kf emulsified oil feed.
