Experimental study on the dewatering behavior of the dredged mud with horizontal drainage by siphon method

抄録

The disposal of the dredged mud has become a worldwide problem recently. There are urgent demands for developing alternatives to dispose the dredged material in a more economical and environment-friendly manner. In this paper, siphon method is proposed to dewater the high-water-content dredged mud with horizontally installed plastic drainage plate. A series of parallel tests are conducted to preliminarily investigate the dewatering and strength behavior of the dredged mud with vacuum and siphon methods, respectively. On the basis of the test results, siphon method is proved to be an effective and energyfree approach to dewater the dredged slurry.
