An environmental protection floating dredging system for removing material from the bottoms of bodies of water, separating it into liquid and semi-solid and solid components by the action of co-acting on-board centrifugal separators and dryers of the solid material dredged and a suction return system for collecting and recirculating the liquid component through the dredging system by way of the dredge head, thus minimizing disturbance of the bottom dredged and pollution by material discharged overboard, and eliminating pollution from dumping of separated solids, which are processed and stored aboard in light-weight dry form adapted for dry-landfill and for use in aggregate mixes in some cases.
