METHOD FOR THE TREATMENT OF RIVER SEDIMENTS AND WATER VEHICLE FOR CARRYING OUT THE SAME

摘要

Extracting a product from sludge of a water body on a water vehicle, comprises obtaining solids in many fractions of different grain size from the sludge, supplying back the coarse solids with a grain size above a first threshold value, and organisms and organic components with a grain size above a second threshold value into the water body, and processing the inorganic solids below the first threshold value to obtain at least one product. An independent claim is also included for the water vehicle for the production of the product from the sludge of the water body by the above mentioned method, comprising at least one device for the production of many fractions of solids present in the sludge.
