to handle between 150,000 and 200,000 m3 annually. The sediment is put

through a separation process similar to the Metha Plant process with few

exceptions. The advantage of this plant is that it is portable and can be

moved to project sites.

Cost

The cost is about $35/m3 of sediment treated. This cost can vary de-

pending on the contaminant of concern, grain size distribution, and the

amount of trash within the system. The $35 includes all costs to the user

(no additional charges for containment or sale of materials are included).

Technology

Another example of successful separation of sand from the silt fraction

was conducted at De Slufter in The Netherlands. This project was completed

in 1987 to contain contaminated sediments dredged from the Port of Rot-

terdam. The 260-hectare site has a capacity of 100 million m3 (see Figure 10).

In an effort to retain as great a capacity as possible, sand is separated
