A contribution for predicting geotextile clogging during filtration of suspended solids

Improvement of Life Expectancy of Jute Based Needlepunched Geotextiles Through Bitumen Treatment

“…This is because bitumen impregnation causes an agglomerated composite structure of jute nonwoven samples, reducing the pore sizes due to superimposing bitumen binder layer being formed on the surface of the both sides of the fabric, which ultimately show a covering and masking effect like a coated fabric, causing and restricting almost all the hydraulic flow properties and also preventing microbes from direct contact to cellulose molecules present in jute. Similar findings have been reported by Faure [17] in a study of clogging of hydraulic flow behavior by suspended solids for Geotextile filtration.…”

Changes of Permeability of Nonwoven Geotextiles due to Clogging and Cyclic Water Flow in Laboratory Conditions

“…Similarly, the results of the studies and observations of filtration behavior of nonwoven geotextiles of Nishigata et al [49] have shown the influence of particle-size distribution on clogging. The studies of many other researchers [20,28,30,50] have also demonstrated that the flow performance of geotextile filters depends on clogging.…”

“…However, the selection of particular nonwoven geotextiles for particular places is a critical decision and the hydraulic properties of the material should be measured [18,19], especially, because in drainage and filter applications, nonwoven geotextiles are the first to be in contact with soft, saturated, and fine soils [20].…”

Modeling the slurry filtration performance of nonwoven geotextiles

“…The filtration and drainage functions are especially attractive in the construction of soil structures such as retaining walls or embankments (Faure et al, 1999(Faure et al, , 2006Tan et al, 1998). In this situation essentially two important characteristics of the geotextile must be considered as they relate to their application: one is the ability to percolate water through the geotextile, generally expressed by the fabric permeability coefficient K; the other is the particle retention capacity of the filter, expressed by geometrical ratios between characteristic particle dimensions of the soil to be retained and a characteristic opening of the fabric (Lombard et al, 1989).…”
