“…Mukhtar et al (2007) reported dewatering animal wastes using geotextile bags and no polymer addition resulted in clogging of the geotextile pores and prevented drainage. Worley et al (2008) also reported chemical amendments should be applied for repeated fillings and effective dewatering of animal wastes using geotextile bags.…”

“…Geotextile technology allows a more flexible approach toward management of aquaculture effluent after discharge from the production system. A geotextile bag is constructed from a high‐strength woven polypropylene fabric and has been used to dewater animal wastes on dairy (Mukhtar et al 2007; Cantrell et al 2008; Worley et al 2008), swine (Baker et al 2002; Cantrell et al 2008), and aquaculture facilities (Sharrer et al 2009). Total suspended solids (TSS) are retained within the bag while the slurry dewaters allowing a filtrate low in TSS concentration to exit.…”

“…The bag must then be disposed in a landfill and plastics can take decades to degrade (Aminabhavi et al 1990). In addition, the cost of a geotextile bag is considerable (Worley et al 2008; Sharrer et al 2009) and destroying it to move solids off‐site may not be economical for a production facility. Additionally, the price of geotextile will most likely continue to increase in the future.…”

Intensive, recirculating aquaculture systems create concentrated wastes high in solid content. Geotextile has successfully dewatered aquaculture effluent; however, burlap, made from natural plant fiber, may provide similar filtering capabilities at a lower cost. The trial was designed as a 2 × 2 factorial to evaluate burlap bags and geotextile bags with or without polymer addition for dewatering Nile tilapia, Oreochromis niloticus, effluent from an intensive biofloc production system. There were no significant interactions (P > 0.05) between the main effects on the removal efficiency of total suspended solids (TSS) concentration. There were no significant differences (P > 0.05) in the main effect of textile; however, there were significant differences (P≤ 0.001) in the main effect of polymer on the removal efficiency of TSS concentration from effluent. Overall, TSS removal efficiency in textile‐only treatments was 81%, whereas textile treatments in combination with polymer removed 98%. Partial budget analysis indicated that the cost per kilogram of solids (dry weight) removed from untreated effluent was US$1.52, 1.51, 0.16, and 0.14 for the geotextile with polymer (GP), geotextile without polymer (GNP), burlap with polymer (BP), and burlap without polymer (BNP) treatments, respectively. The BP could provide an effective treatment process for removing TSS in discharged effluent.

“…If the accelerant can collapse the waste stream structure effectively then high percentages of these contaminants can be contained within the geotextile tube. This ability of chemical dewatering accelerants to trap organic compounds has also been demonstrated in the geotextile tube dewatering of animal waste, where compounds of organic nitrogen and phosphorus have been fully contained within the geotextile tubes (Worley et al 2004(Worley et al , 2005.…”

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, various waste streams and contaminated sediments. The paper reviews the three main geotextile containment units in use -geotextile tubes, geotextile containers and geotextile bagsand analyses their use in a wide range of hydraulic and environmental applications. Special attention is given to the use of geotextile containment for the isolation, dewatering, and disposal of specific waste streams and contaminated sediments. Note: This paper is an updated version of the Giroud Lecture presented by C.

“…Geosynthetic tubes have been used to build dikes or small dams for flood control, water diversion, groundwater recharging, irrigation or land reclamation purposes (Perry 1993;Plaut and Suherman 1998;Alvarez 2007;Saathoff et al 2007;Shin and Oh 2007;Worley et al 2008;Yan and Chu 2010;Leshchinsky et al 1996 andPilarczyk 2000). Sometimes, the geosynthetic tubes have to be placed on soft ground.…”

Geosynthetic tube has been used for dike constructions on soft ground. We need methods to design geosynthetic tubes that rest on deformable foundation. In this paper, 2D analytical and numerical methods are proposed to analyze the stress and deformation of the impermeable geosynthetic tubes resting on deformable foundation. The analytical method is proposed by using the 1D consolidation relationship or the e-log-p curve as an approximation. As the stress-strain relationship is nonlinear, this method is better than the Winkler method. The vertical pressure distribution in the soil is calculated using the Boussinesq equation. Numerical analyses are also carried out to evaluate the accuracy of the proposed method and good agreement between the results from the analytical method those from numerical methods was achieved.
