Περίληψη
A pore network consisting of a monolayer of glass beads was constructed
for experimental investigation of the effects of acoustic waves on the dissolution and
mobilization of perchloroethylene (PCE) ganglia. Dissolution experiments were conducted
with acoustic wave frequencies ranging from 75 to 225 Hz at a constant pressure amplitude
of 3.68 kPa applied to the inlet of the monolayer. Ganglia mobilization experiments
were conducted with a constant acoustic wave frequency of 125 Hz and acoustic pressure
amplitudes ranging from 0 to 39.07 kPa. Effluent dissolved PCE concentrations were
observed to increase in the presence of acoustic waves with the greatest increase (over
300%) occurring at the lowest frequency employed (75 Hz). Acoustic waves were also
observed to mobilize otherwise immobile PCE ganglia, break them apart, and further
enhance dissolution.
