Contaminated sediments from dredging operations need to be treated because they are a risk to public health and the marine environment. The treatment possibilities are discussed in the context of complex factors such as diversity in granular distribution and the mix of contaminating chemicals and heavy metals. Hydrocyclones are put forward as a feasible separating technique, and the separation of sediments into coarse and fine fractions is discussed--the finer material containing the major percentage of contaminants.
