...E. M. Palmeira; M. G. Gardoni Geotextiles are well-established filters in geotechnical and geoenvironmental engineering owing to their rapid and straightforward installation, cost-effectiveness, and environmental advantages. To properly fulfil the filter function, geotextiles must retain base soil...

...E. M. Palmeira Geotextiles have been used as filters in geotechnical and geoenvironmental works for decades. Despite their broad utilization, these filters still find obstacles to the expansion of their application in larger projects and under complex soil and flow conditions. However...

...E. M. Palmeira; H. L. Trejos Galvis Geotextiles are commonly used as filters in geotechnical and geoenvironmental works. For a proper design of a geotextile, filter pore dimensions and gradation are necessary and the equivalent diameter of these pores depends on the confining vertical stress acting...

... field and laboratory work demonstrated that granular materials trapped the majority of PCB-contaminated soil without impeding hydraulic performance; however, fines were escaping. Extensive column testing in the laboratory has shown that a nonwoven geotextile filter can be applied with success...

... treatment. The geotextiles filtered organic suspended solids and hosted growth of microorganisms. The test liquid was primary treatment effluent that treated combined sewage (wastewater plus stormwater runoff). The project used 10.16 cm diameter packed columns containing alternating layers of gravel, sand...

... and by the soil sample preparation technique employed. The results suggest that current retention and permeability criteria for geotextile filters can be excessively conservative. Discussions on geotextile performance in the test and under field conditions are also presented as well as limitations and new...
