Showing page 1. This is achieved principally using self discharge bucket wheel, drag scraper or excavator via conveyor systems.When contaminated (toxic) sediments are to be removed, or large volume inland disposal sites are unavailable, dredge slurries are reduced to dry solids via a process known as dewatering.
