The suitability of electrokinetic remediation for the removal of metal pollutants from silty-clayey dredged marine sediments is currently being investigated in the SEKRET (“Sediment ElectroKinetic REmediation Technology for heavy metal pollution removal” – ref. LIFE12 ENV/IT/442) project, funded by the European Commission in the framework of the LIFE+ Environment Policy and Governance projects and started in early 2014. The main objective of the project is to build and operate a pilot-scale demonstration plant for the application of electrokinetic remediation of dredged sediments from the Livorno harbour, a large harbour site located in central Italy along the Tyrrhenian sea coastline. In this framework, a 150-m3 treatment tank was recently built in a dedicated area and is about to be run into operation. This work presents the general design considerations for the pilot-scale electrokinetic treatment plant, which were derived from the results obtained during a preliminary testing campaign conducted at the laboratory scale, where several process conditions and enhancing agents were investigated. Technical details about the various process units are provided and the selection of the required equipment is also described.
