摘要
Sediments are treated to give a material which can be deposited on a waste dump in a long term environmentally tolerated manner, or an environmentally tolerated building material, in particular for waterproofing coatings, the contaminated sediments from water to be conditioned being dewatered to a water content of at most about 140% relative to their dry weight; the sediments from water dewatered to this extent being substantially homogeneously comminuted; and the comminuted sediments from water being homogeneously mixed with about 4 to 15% - relative to their dry weight - of a kaolinitic clay to give a (sediment/kaolinite) mixture; a device for carrying out this process is also described.
