This research focuses on electrokinetic dewatering and settling of contaminated sediment. A series of laboratory experiments with different magnitudes of applied voltage is performed with artificially made contaminated sediment mixed with contaminant. Investigated parameters in experiments are settlements of the slurry specimen, volumes of water extracted from the slurry specimen, and the changes in fluid content of the specimen. The results show that the sedimentation rate and velocity are varied and controlled by the applied voltage. From the test results, a significant investigation is derived for the mechanisms associated with dewatering and sedimentation of contaminated sediment. A coupled effect of electrokinetic dewatering and settling processes is investigated.
