A Method for Treatment of Contaminated Dredged Sediment: Electrolysis Combined with Stabilization and Solidification
Other conference contribution, 2022
Electrochemical treatment was tested at laboratory scale to degrade toxic tributyltin (TBT) and remove metals from marine sediment. After the electrolysis, the sediment was stabilized using the S/S technique, and the effect of electrochemical pretreatment on the strength and leaching properties of the stabilized sediment was investigated. Finally, the climate impacts of the investigated methods are assessed depending on the metal content in the sediment. The results indicate that electrochemical pretreatment could be done to lower the leaching of contaminants from S/S sediment and that the metal recovery could be beneficial, especially if the sediment is heavily contaminated with metals.
