... that these filters have been very successful, particularly bearing in mind the small number of failures in comparison with the huge number of applications of geotextile filters. Geosynthetics Filters Geotextiles Filter behaviour Clogging Piping Geotextiles have been extensively used as filters...

...N. Moraci; M. C. Mandaglio; S. Bilardi The paper focuses on the evaluation of the long-term behaviour of geotextile filters in contact with cohesionless soils. The clogging, blinding and piping levels of the filtering systems have been evaluated analysing the results of long-term filtration tests...

...A. Das; B.V.S. Viswanadham ABSTRACT : The objective of this paper is, through laboratory experiments, to examine the effect of discrete and randomly distributed fibers on the piping behavior of soil. A silty sand type of soil having 20% fines was selected in the present study. Two types...

... of dewatering time and amount of piping under anticipated field conditions. This novel approach guides the selection and evaluation of candidate polymers, which can be further evaluated in greater detail using pilot-scale tests. It is demonstrated that considerable enhancement can be achieved in the dewatering...

... value for four sludge-geotextile systems. Progressive increase of the permeability was observed for one geotextile. Results from the filtration tests are compared and discussed. KEYWORDS: Filtration, Sludge, Geotextile, Permeability, Soil retention, Piping. AUTHORS: W. Haegeman, Professor, Laboratory...
