SEPARATION TEST OF RECTANGULAR ELECTROFLO TATION CELL WITH PACKED-BEDTYPE SACRIFICIAL ELECTRODES

A separation test of an O/W emulsion was conducted by using a rectangu lar cell fitted with packed bed type sacrificial electrodes. The conti nuous separation process was represented by a first-order kinetic rate equation and a two tanks-in-series mixing model as previously reporte d (Osasa et al., 1996). Three types of electrodes were examined to inc rease the dissolution rate of aluminum pellets. The most efficient typ e of electrodes used was one in which aluminum pellets were placed on both an anode and a cathode and the polarity was switched at regular t ime intervals.
