Constriction Size of Geotextile Filters
Filtration performance of nonwoven geotextiles strongly depends on pore opening constriction size, i.e., the minimum opening size of flow channels across the geotextile. Currently available methods of pore opening characterizations do not provide accurate information about the constriction size. This paper presents the constriction size distributions of eleven nonwoven geotextiles commonly used...
متن کاملField Performance of Geotextile Reinforced Sludge Caps
Geosynthetic reinforced capping of highwater content waste materials is becoming an efficient and economic way of dealing with the confinement of the contaminants. To define the filtration performance of sludge-geotextile systems and investigate their durability, ten sludge lagoon test cells were constructed using of a lightweight fill, i.e. a wood chip/soil mixture over different geotextiles. ...
متن کاملGeotextile Pore Structure Characterization Using Image Analysis
Filtration performance of geotextiles strongly depends on their pore structure parameters, i.e. percent open area (POA), pore opening size distribution (PSD) and constriction size distribution (CSD). Current methods of determination of pore structure parameters contain inherent disadvantages whereas image analysis can be used effectively for this purpose. Two new image-based PSD and CSD determi...
متن کاملDewatering Fly Ash Slurries Using Geotextile Containers
The design of geotextile containers for dewatering applications typically requires good retention of the confined fill material solids. This becomes difficult to achieve when the fill material is fine grained and the pore openings are large. Furthermore, the proper retention becomes critical if the confined material is contaminated. Fly ash is one of the fine-grained geomaterials that exhibit b...
متن کاملFiltration Performance of Two-Layer Geotextile Systems
Nonwoven geotextiles are commonly used in filtration applications. For some applications, however, a nonwoven geotextile filter may not have the required mechanical properties to withstand deformations, and an additional woven geotextile is usually employed in design. While reinforcement is an important function expected from these two-layer geotextile systems, filtration is another function th...
