Electrokinetic Treatment of Contaminated Marine Sediments

Giorgia De Gioannis, Aldo Muntoni, Alessandra Polettini, AND RaFFAELLA PoMI 

Despite decades of research, surprisingly little is known about successful treatment of contaminated sediments. Presently, the most common approach to management of dredged sediment is generally limited to land (or aquatic) disposal. Confined aquatic disposal (CAD) involves underwater contaminated sediments capping with clean sediments or sand, geotextiles, liners, or even reactive barriers, either with or without lateral confinement. Sediments are deposited in natural or artificial depression, usually by means of a clamshell or a hydraulic pipeline. Capping may also shift

ELECTRO KINETIC TREATMENT OF CONTAMINATED MARINE SEDIMENTS 

With regard to the subject of this chapter, the configuration of CAD and CDF cells, under some circumstances, allows for the application of several treatment techniques (Gardner, 2005), among which electrochemical remediation is believed to be particularly suited for (Acar, 1992 Acar and Alshawabkeh, 1993).
