ABSTRACT: This study was on the evaluation of a desorption-sorption process for remediation of hydrocarbon-contaminated sediments. Furthermore, the effect of two influential factors including retention time and solid load was studied. A laboratory scale system was designed and built for remediation of sediments in a short period of time. A strong turbulence vessel (about16000 rpm) was used to increase desorption of hydrocarbon contaminants from sediments. A sorption packed column containing hydrophobic silica aerogel granules was used to remove the contaminants in order to improve the quality of the effluent slurry. After 45 minutes, 29.5% of total petroleum hydrocarbon (TPH) removal from sediments was achieved. Different applied ranges of retention time in the agitator (0.19 and 0.43 min) and sediment solid loads (5, 10 and 15 g/l) did not show a significant effect on the efficiency of the process. The processed sediment and water in effluent followed the allowed Canadian governmental and provincial environmental criteria for fresh water.
