Abstract

The consideration of a dredged material confinement facility as a solid-liquid separation system requires the use of filter systems for clarifying disposal area effluents. Presented herein are: (1)The types of tests that were performed; (2)the rationale for selecting the range of values for the parameters; (3)the methods and techniques for conducting the tests and collecting the data; (4)an analysis and review of the results. Conclusions are advanced regarding the characteristics and performance capabilities of sands or gravels and anthracites as media for nonmechanized deep bed filtration systems. In general, sands and anthracites with effective grain sizes smaller than 2. 0 mm and 3. 5 mm and larger than 0. 4 mm and 0. 8 mm, respectively, are strong candidates for use in disposal area filter systems.
