A study on the differences in the flocculation of dredged slurries and the influencing mechanisms [PDF]

open access: yesWater Science and Technology, 2019
Abstract In the water treatment process of natural water bodies, a large amount of dredged slurry with high water content is generated and required for treatment. The coagulation–flocculation method can improve the efficiency of separation, and a suitable scheme is of great significance.

Effect of sand on the vacuum consolidation of dredged slurry [PDF]

open access: yesMarine Georesources & Geotechnology, 2017
Vacuum preloading is often used to improve the geotechnical properties of dredged slurry. Although the performance of this method has improved with rapidly developing technology, soil columns usually formed on the drainage boundary induce the decrease of permeability around the boundary, thereby limiting the further development of this method.

Clogging Behaviors in PVD and Their Evaluation Criteria for Dredged Mud Slurry

open access: yesWater, 2023
During the consolidation period of vacuum preloading drainage of dredged mud slurry, the clogging behaviors of the filter drainage structural layers and the core boards of prefabricated vertical drains (PVD) determine the drainage capacities of PVD. However, currently, there is a lack of comprehensive research on the evaluation criteria for these two ...
