Abstract
In the bagging and dewatering process, dredged soil and other slurry with high water content are bagged and dewatered using permeable geotextile and stacked to make banks. This process proven to be effective in preventing the spread of dioxin, PCB, and other substances as long as turbid water does not escape from the slurry-filled geotextile tubing as these substances are adsorbed by soil grains. However, the small fraction of turbid water that invariably escapes from the geotextile tubing when it is filled with slurry is termed the initial turbidity. Given that bagging and dewatering involved filling geotextile bags with slurry using a pump, we developed a method that minimizes the dispersal of contaminated soil.
