A pore network consisting of a monolayer of glass beads was constructedfor experimental investigation of the effects of acoustic waves on the dissolution andmobilization of perchloroethylene (PCE) ganglia. Dissolution experiments were conductedwith acoustic wave frequencies ranging from 75 to 225 Hz at a constant pressure amplitudeof 3.68 kPa applied to the inlet of the monolayer. Ganglia mobilization experimentswere conducted with a constant acoustic wave frequency of 125 Hz and acoustic pressureamplitudes ranging from 0 to 39.07 kPa. Effluent dissolved PCE concentrations wereobserved to increase in the presence of acoustic waves with the greatest increase (over300%) occurring at the lowest frequency employed (75 Hz). Acoustic waves were alsoobserved to mobilize otherwise immobile PCE ganglia, break them apart, and furtherenhance dissolution.
