...V. L. Silva; M. G. A. Gardoni; K. C. Pimentel Geotextile tubes are generally used in hydraulic and marine applications such as coastal protection and flood control. They are also used to dewater sludge from sewage treatment plants and dredged materials. Studies have been carried out to derive...

...C. R. Ratnayesuraj; S. K. Bhatia Geotextile tubes are used to dewater slurries, sediments, and wastes. With their extensive use for dewatering, the desire to maximize both dewatering rate and sediment retention has led to the use of chemical accelerants, which have become a standard practice...

...M. M. Khachan; S. K. Bhatia Geotextile tubes have been widely used for the dewatering of high water content fine sediments. Fine sediments include lake sediments, organic soils and coal combustion products, which generally have low shear strength. Several researchers have emphasized the effect...

...W. Guo; J. Chu; B. Zhou Permeable geotextile tubes are usually made by sewing geotextile sheets together and then filling with clay slurry or sand. However, the tensile strength of a seamed woven geotextile material is usually only half of that of the seamless geotextile sheet. A new seam method...

...W. Guo; J. Chu; B. Zhou ABSTRACT: Geotextile tubes made of woven geotextile materials have been widely applied to dewater waste sludge such as digested bio-solids, sewage sludge, dredged materials, industrial solid wastes, fly ash and coal slurry. However, the dewatering process of single...

...M.M. Khachan; S.K. Bhatia; R.A. Bader; D. Cetin; B.V. Ramarao ABSTRACT: Polyacrylamide-based conditioners have become an essential component of the geotextile tube dewatering processes. These conditioners act as flocculants, binding fine sediments through charge neutralisation and particle bridging...

...T.W. Yee; C.R. Lawson ABSTRACT: The geotextile tube dewatering process consists of multiple cycles of slurry filling and drawdown in order to achieve a desired final volume reduction and solids concentration increase. Relatively simple relationships have been developed in the past to calculate...

...E. C. Shin; Y. I. Oh This paper presents the geotechnical behaviour of geotextile tubes based on the results of two field model tests. The tests were performed on two types of dredged material (sand and silty clay) at the Songdo land reclamation site in the Bay of Incheon, Republic of Korea...
