ABSTRACT:
A mesh enclosed container is provided to remove melt water from frozen blocks of contaminated sediment which has been extracted from a marine environment. The mesh enclosure has a number of porous wicking tubes for insertion into corresponding cavities in the frozen sediment blocks. Wicking material is inserted into the tubes to enhance melt water flow out of the sediment blocks during the thawing cycle. A sealed container may be provided to enclose the block and meshed container to prevent escape of volatile materials during the thawing cycle. The sealed container will also collect melt water accumulated during the thawing cycle. A method of melting frozen marine sediment blocks is provided to recover treated water.
