The effect of initial water content on the consolidation of dredged slurry under vacuum preloading
Rock and Soil Mechanics, 2021 In the process of treating the dredged slurry under vacuum preloading combined with the prefabricated vertical drains (PVDs), a dense “soil column” with low permeability will be formed around the PVD, which results in a poor drainage condition and an ...

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

Review and Integrated Framework for Deep-Sea Mineral Resources, Ecological Influence, and Future Development. [PDF]
Int J MicrobiolAs global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

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