Abstract
The potential application of acoustic waves to remediate groundwater aquifers contaminated with dense nonaqueous phase liquids (DNAPL) was investigated. Under simulated conditions of groundwater acqifier, the mass transport and dissolution DNALP were significantly enhanced by the application of acoustic waves. Pump-and-treat was the primary method that used for remediating groundwater with DNAPL. It was observed that the acoustic waves increases the dissolution and aqueous transport of DNAPL in the groundwater aquifers thus enhanced the efficiency of the pump and treat methodology. An experiment was conducted to design the water saturated packed columns in order to test the effect of acoustic waves on the mass transport and dissolution of DNALP. The Result shows a significant increase in the mass transport rate of the DNALP in the porous media is due to the acoustic pressure waves.
