  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • Cylindrical Expansion Test for Tensile Properties of Geotextiles

    This technical note describes a new apparatus and testing procedure to perform rapid quality control and assessment of the design parameters of geosynthetic materials. The cylindrical expansion test (CET) is based on the principles of the extension of a geosynthetic specimen wrapped around the surface of an expanding thin-wall cylinder. The parametric study conducted on two nonwoven polyolefin ...

  • Dewatering with Geotextile Bags - South Gippsland, Australia (Water Treatment) - Case Study

    A simple, cost effective new method of dewatering sludge is now available in Australia, writes Bill Kelly from CRS Industrial Water Treatment. The use of geotextilcs for containment and dewatering came about as a result of a major flood event in Holland in the 1950s. It prompted Dutch marine engineers to seek new methods and materials to build structures for coastal defences. The ...

  • Treatment of domestic greywater by geotextile filter and intermittent sand filtration bioreactor

    Intermittent sand filtration (ISF) is an efficient system for treatment of greywater; however, the high quality of effluent and the simple set-up contrast with the high failure rate due to clogging of surface layers. The efficacy of several polypropylene non-woven geotextiles (apparent opening size from 0.10 to 0.18 mm) used as primary treatment filters to remove suspended particles from ...

  • In-Plane Air Flow Through Needle-Punched, Nonwoven Geotextiles Under Normal Loading

    Knowledge of the in-plane permeability of nonwoven geotextiles to air and other gases has important applications including, for example, the transport and collection of methane gas beneath landfill caps. The results of in-plane flow measurements of air through eight different needle-punched, nonwoven geotextiles are presented. Air flow was measured using a radial flow device under a range of ...

  • Biological regeneration of ferric (Fe3+) solution during desulphurisation of gaseous streams: effect of nutrients and support material

    This paper evaluates the biological regeneration of ferric Fe3+ solution during desulphurisation of gaseous streams. Hydrogen sulphide (H2S) is absorbed into aqueous ferric sulphate solution and oxidised to elemental sulphur, while ferric ions Fe3+ are reduced to ferrous ions Fe2+. During the industrial regeneration of Fe3+, ...

  • Equipping a once-fatal highway to deliver solid future performance

    Background Stretching 1189 miles along the southeastern coast from Virginia to Florida, the Ocean Highway (US 17) mixes magnifi cent scenery with unpredictable driving conditions. In 2005, the South Carolina Department of Transportation (SCDOT) called its 211-mile stretch of US 17 one of the deadliest roads in the nation; and between 1997 and 2005, the highway experienced nearly 1,000 ...

  • Millstone Manor Parking Lot Stabilization - Case Study

    Shallow utilities won’t get in the way of our high strength woven geotextile’s ability to stabilize this parking lot. Millstone Manor, an apartment complex located right next to the Ogden River at the base of the Wasatch Mountains, had been having difficulty stabilizing their parking areas for years. Due to its proximity to a water source and resulting soil types, the CBR ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...
