“…The obtained results show that the gradient ratio GR has increased from 0.75 to 0.9 under tested hydraulic gradient and soil-gradient ratio SGR 17 has increased from 1.15 to 1.42 under tested hydraulic gradient. The gradient ratio and soil-gradient ratio have increased with time and with a higher hydraulic gradient because of clogging mechanism (Kutay & Aydilek, 2005;Wu, Hong, Yan & Chang, 2006;Fannin, Palmeira, Srikongsri, & Gardoni, 2008;Sabiri et al, 2017) but signifi cant clogging occurred in the 17-mm soil layer situated in distance from 8 to 25 mm above nonwoven geotextile sample.…”

Nonwoven geotextile have been widely used for filtration. In this paper, the clogging potential for a soil-geotextile system were assessed using laboratory tests. An ASTM modified gradient ratio test device was used to determine gradient ratio as well as soil-gradient ratio. One type of nonwoven geotextile and soil were used to simulate the conditions in drainage system. The obtained results indicate that the gradient ratio and soil-gradient ratio increases with time because of clogging mechanism. However, the tested geotextile can be used as fi lter for soil with fine content of 20%.

“…This phenomenon has been studied by several researchers such as Le Coq (1996), who proposed a model to describe the increase in head loss through a filter due to clogging and Faure et al (2006), who proposed a method to predict geotextile clogging during filtration of suspended solids. This last study focuses on clay suspensions with very low concentrations (inferior to one gram per litre) and is extended by a very recent study conducted by Sabiri et al (2017).…”

This paper presents the results of an experimental study of various geotextiles used to filter clayey sludge. The use of geotextiles to filter clayey sludge or suspensions of fine particles in water is more complex than that for filtering suspensions of granular soils. In practice, such applications generally use flocculants to postpone the formation of a low-permeability filter cake. The objective of the present study, which does not use flocculants, is to determine how geotextile characteristics affect the capacity of the geotextile to filter clayey sludge. Three key questions are addressed: (1) What are the main differences between vertical and horizontal filtration? (2) How do geotextile characteristics (nature, opening size, permeability, etc.) affect its capacity to filter clayey sludge? (3) How do clayey sludge characteristics (i.e., grain size distribution and concentration) and the type of flow (i.e., constant head or constant flow) affect the filtering capacity of geotextiles? To evaluate the capacity of a geotextile to filter clayey sludge, we propose three relevant criteria and analyse two filtration phases induced by different cake-formation processes (controlled by the geotextile and controlled by the filter cake).

“…Geotextiles function as filters and prevent erosion of soils in contact with the filter. They are more permeable and thinner compared with granular filters (Giroud, 2010;Sabiri et al, 2017). Geotextiles enable water to pass through while retaining the soil structure stable by preventing migration of soil particles.…”

One of the major functions of geotextiles is to control soil erosion. Apparent opening size and permeability of non-woven geotextiles are properties that control erosion. In this manuscript, soil taken from an eroded pond is considered for the study. Filtration and clogging behavior of the several geotextiles are studied under laminar flow conditions and at three different hydraulic gradients. Results facilitate selecting the appropriate geotextile based on permeability, filtration and clogging for use as erosion control
