...S. T. S. Paranhos; M. A. Aparicio-Ardila; J. Lins da Silva Geotextile tubes have been presented as a viable alternative for dewatering sludge generated in different industries, characterised by having fine grain and high moisture content. The material commonly used to develop this system is woven...

... of coarse and fine particles – that is, silty sand – is complex. For this reason, the modified geotextile tube (MGT) was invented to optimize the filling and dewatering or consolidation performance of geotextile tubes. To assess the behavior of MGTs, experimentation and theoretical analysis were conducted...

...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...

...M.G.A. Guimarães; D.C. Urashima; D.M. Vidal ABSTRACT: Sludges generated during purification of water for human consumption are produced in large volumes and have high environmental polluting potential. The sludge dewatering technique using geotextile closed systems has been used to reduce...

...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...

...C.-C. Huang; M. Jatta; C.-C. Chuang ABSTRACT: Geotextiles are increasingly being utilised in dewatering dredged reservoir sediment, as part of the sustainable management of reservoirs. To this end, analytical models for evaluating the effluent rate through geotextile dewatering systems have been...

...S. Cantré; F. Saathoff ABSTRACT: Geosynthetic tubes are increasingly being used for dewatering projects processing many different types of sludge, such as dredged materials, industrial and sewage sludge. Although there is still a lack of reliable design procedures, especially with respect...

...R. Satyamurthy; S. K. Bhatia Results from laboratory investigations for evaluation and enhancement of the dewatering performance of fine silt slurry are presented. These experiments were conducted with and without polymer conditioning of the slurry. One type of soil and five types of geotextile...

...C. R. Lawson Historically, geotextile containment has been used to encapsulate sandy soils to permit their use as flexible, erosion-resistant, mass-gravity structures in hydraulic and marine applications. More recently, geotextile containment has been used as a means of disposing of, and dewatering...

...C.-C. Huang; S.-Y. Luo A series of falling-head dewatering column tests (FHDT) was performed using a mixture of water and reservoir sediment and four types of woven geotextile to investigate the factors that control the permeability and piping of underdrainage dewatering systems such as geotextile...
