A laboratory study of landfill-leachate transport in soils.
Continuous flow experiments were conducted using sand-packed columns to investigate the relative significance of bacterial growth, metal precipitation, and anaerobic gas formation on biologically induced clogging of soils. Natural leachate from a local municipal landfill, amended with acetic acid, was fed to two sand-packed columns operated in upflow mode. Degradation of the influent acetic aci...
متن کاملUtilization of Natural Zeolite and Perlite as Landfill Liners for in Situ Leachate Treatment in Landfills
The potential long term environmental impacts of a landfill on groundwater quality depend on its liner material properties. In case synthetic liner materials are damaged during the construction or operation, many of the original chemical and biological constituents are removed by filtration and the adsorptive action of natural liner materials such as natural zeolite, perlite and bentonite miner...
متن کاملUse of artificial neural networks to estimate installation damage of nonwoven geotextiles
This paper presents a feed forward back-propagation neural network model to predict the retained tensile strength and design chart in order to estimation of the strength reduction factors of nonwoven geotextiles due to installation process. A database of 34 full-scale field tests were utilized to train, validate and test the developed neural network and regression model. The results show that t...
متن کاملDigital Image Analysis to Determine Pore Opening Size Distribution of Nonwoven Geotextiles
The filtration performance of a geotextile is controlled by its pore opening size distribution ~PSD!. Current methods for determining PSD are mostly indirect and contain inherent disadvantages. Recent technological advancements in image analysis offer great potential for a more accurate and direct way of determining the PSD of nonwoven geotextiles. A new and accurate method of image analysis fo...
متن کاملComparison Of Hydraulic Conductivity Test Methods for Landfill Clay Liners
Accurately measuring the in situ hydraulic conductivity (permeability) of a clay liner is a major factor in the construction of landfill containment systems. Laboratory and large-scale field test methods are often utilized on test pads constructed prior to placement of the production liner to determine the hydraulic conductivity of the clay. While these test methods provide reliable results, th...
