Objectives

The content of heavy metals and organic contaminants is primarily governed by the grain size. The finer the particles and the higher the content of organic matter in the sediment, the higher will be the content of contamination. Thus, the separation of the Elbe sediments into several fractions is required for reliable processing of dredged material taking into account the sediment particle size and the contaminant distribution. Hence the primary target is to dewater and separate Elbe sediments in order to reduce the total volume by separating the contaminated fraction. At the same time the fraction to be land filled is reduced in volume and weight. A secondary target is the improvement of the water and sediment quality of the Elbe estuary. Furthermore the material could possibly be used for other purposes e.g. as construction material. In this way the necessary area for a disposal site for dredged materials, could be minimized.
