Abstract Urban development has significantly accelerated soil erosion, presenting a serious environmental challenge. Among the available solutions, well-established vegetation is proven to dramatically reduce erosion rates. Geosynthetic rolled control products (RECPs) have shown be highly effective in not only minimizing but also promoting growth. With sustainability becoming critical focus, importance of RECPs taken center stage. However, few studies thoroughly addressed technical,...

Results from laboratory investigations for evaluation and enhancement of the dewatering performance fine silt slurry are presented. These experiments were conducted with without polymer conditioning slurry. One type soil five types geotextile used. The optimal conditions investigated using one woven geotextile. An innovative methodology is proposed determining considerations a combination simple bench-scale tests (jar sedimentation test, jar pressure filtration test). current state practice...

ABSTRACT: Polyacrylamide-based conditioners have become an essential component of the geotextile tube dewatering processes. These act as flocculants, binding fine sediments through charge neutralisation and particle bridging, resulting in faster rates greater retention sediments. Recently, however, momentum has begun to shift towards use sustainable materials. Natural such starch chitosan, are increasingly being tested attractive alternative synthetic polymers. Researchers identified a...

To address the dropoff of women in engineering at graduate level, Women Science and Engineering (WiSE) program Syracuse University collaborated with Graduate School Colleges Computer Arts Sciences to create a for students science engineering. This paper provides an overview available data on barriers they encounter. It then discusses authors' experiences WiSE Future Professionals Program (WiSE-FPP). Assessment showed that WiSE-FPP provided strong peer support network participants gave...

Geotextile tubes are used to dewater slurries, sediments, and wastes. With their extensive use for dewatering, the desire maximize both dewatering rate sediment retention has led of chemical accelerants, which have become a standard practice in geotextile tube projects. A variety test methods currently evaluate performance, ranging from small-scale Falling Head Tests (FHTs), medium-scale Hanging Bag (HBTs), Geotextile-tube Demonstration (GDTs), full-scale pilot tests. However, few studies...

Geotextiles are widely used in filtration applications. For continued growth this area, it is critical that geotextiles be properly designed for these applications to prevent failures. The geotextile property most directly related the design of a as filter pore-size distribution geotextile. main objective study was compare performance following six different test methods evaluate geotextiles: dry sieving, hydrodynamic wet bubble point method, mercury intrusion porosimetry, and image...

Geotextile tubes with polyacrylamide flocculants are widely used in dewatering applications. Due to variations solid concentrations during dredging, excess flocculant is sometimes released into the environment, where it might have toxic effects. This study determined optimum doses for a cationic (CPAM) and natural-based polymer alternative, starch (C. Starch). Slurry samples were treated 50% overdoses of each compound, residual measured. Overdosed C. Starch resulted low residuals (<2 ppm),...

Geotextile tubes have successfully been used by virtually every industry today to dewater a variety of sediments, slurries, by-products, and wastes. Despite this, the dewatering currently lacks uniformity in regards establishing testing standards assessing performance. Prior full-scale tube deployment, lab and/or field tests are typically performed evaluate Preliminary bench such as falling head test (FHT) pressure filtration (PFT) often candidate polymers efficiency. The mid-scale hanging...

Geotextile tubes have been used to dewater a variety of materials, including dredged sediments, mine tailings and mineral fines, municipal sewage sludge, agricultural, manufacturing, industrial wastes. Synthetic polymers, typically polyacrylamide-based, are commonly in geotextile tube dewatering applications as flocculants enhance the rate retention fines. Depending on specific nature flocculant, flocculation fine particles occurs by charge neutralization, bridging, or combination both....
