CHEMICAL-PHYSICAL TREATMENTS OF MARINE CONTAMINATED SEDIMENTS – A COMPARISON

Managing of sediments coming from dredging operations in ports, harbor areas and navigation waterways has to deal with huge quantities of highly contaminated material. As a matter of fact, due to routine operations, to the need of deepening fairways and ports, and, eventually, to remediation activities, every year more than 200⋅106 m3 of dredged materials are produced throughout Europe. Chemical-physical treatments are generally used in order to separate the contaminated fraction from the clean one in order to reduce the quantity of sediments to be disposed of
