Abstract
Feasibility of on-site treatment for contaminated marine sediments (environmental dredged materials) in KOREA which has very narrow land, approximately 100,000 km2, was investigated on the basis of particle separation and washing technologies to solve the scarcity of various treatment and disposal methods. Since national environmental standards related with ocean dumping of dredged materials were restricted form 2008, the decision of alternative treatment methods could be one of the most important factors for environmental dredging. More than 250 methods have been used in the remediation of contaminated sediments at well developed nations such as U.S.A. and European countries. Although the remediation mechanism of sediments is similar to that of soil, fine particles (< 75 um, ~10 %) of soil could be usually separated and then finally treated at landfill sites. On the contrary, the portion of fine particles (< 75 um) is around 70 ~ 90 % in the particle size distribution of marine sediments. Besides both high content of organic matters and chlorine ions might be also limit factors. Thus only a few technologies which were used for the remediation of contaminated soil were revised and then tried to treat contaminated marine sediments in KOREA.es to solve the scarcity of various treatment and disposal methods.
