Laboratory Simulation of Chemical Evaporation from Dredge-Produced Sediment Slurries
Environmental Engineering Science, 2004A laboratory-scale apparatus and associated chemodynamic transport model was tested with samples of field-contaminated sediment containing high concentrations of low volatility polyaromatic (PAHs) and high volatility petroleum hydrocarbons (BETXs). The experiments were designed to measure the flux to air while attempting a realistic simulation of the ...

Improved Vacuum Preloading Method for Consolidation of Dredged Clay-Slurry Fill
Journal of Geotechnical and Geoenvironmental Engineering, 2016AbstractAn improved vacuum preloading method was developed to consolidate clay-slurry fill that is hydraulically placed in seawater for land reclamation. This method adopted both a vacuum and an air-pressurizing system. In the vacuum system, a new connector to connect each prefabricated vertical drain (PVD) directly to a horizontal vacuum pipe is used ...

Vacuum Preloading Combined with Intermittent Electro-Osmosis for Dredged Slurry Strengthening
Geotechnical Testing Journal, 2019Abstract Vacuum electro-osmosis is a useful method for strengthening dredged slurry; however, this technique is not widely applied because of its high power consumption and decreased efficiency in the later stages. Appropriate current intermittence is an important approach to improving the efficiency and reducing the power consumption of

Physicochemical Treatment of Dredged Clay Slurry Waste for Land Reclamation Purpose
2018Application of chemically solidified dredged marine clay as land reclamation fill can not only mitigate the issue of local scarcity of ideal filling material, but also allow significant volumes of unwanted marine clay arising from dredging to be disposed economically and ecologically.

Effects of Column Diameter on Setting Behavior of Dredged Slurry in Sedimentation Experiments
Marine Georesources & Geotechnology, 2015This article investigates the influence of dimensions of a settling column on the settling mode and the settling rate. End conditions of the settling stage in the hindered settling were also analyzed. It was found that the settling mode in a column with a smaller diameter tends to be consolidation settling.

Strength behavior of dredged mud slurry treated jointly by cement, metakaolin and flocculant
Applied Clay Science, 2020Abstract Application of the flocculation-solidification combined method (FSCM) for building a surface working platform is a reasonable option to resolve the personnel and equipment accessibility problem at a dumping site filled with dredged mud slurry at extra high water content (EHW-MS).

Environmental Science and Pollution Research
Addressing the substantial yearly production of waste dredged slurry with high water content, it is imperative to adopt effective technical treatments for sustainable development. This paper establishes that the curing-flocculation-vacuum filtration (C-F-VF) method efficiently converts high-water content dredged slurry into back-fill soil, achieving ...

Vacuum consolidation of dredged slurry improved by horizontal drainage-enhanced geotextile
Geosynthetics InternationalThe vacuum consolidation behavior of dredged slurry improved by horizontal drainage-enhanced geotextile (HDeG) application was investigated. For comparison, vacuum consolidation tests using a prefabricated vertical drain (PVD) and layered prefabricated horizontal drains (PHDs) were conducted. Based on the test results, it was found that by using HDeG,
