Green dewatering with geotextile tubes
December 1st, 2021
TenCate Geotube dewatering solutions offers substantially lower energy consumption. Photograph courtesy TenCate Geosynthetics When planning a dewatering operation, bridging the gap between efficiency and sustainability is essential. TenCate Geotube helps manage this balancing act. Not all dewatering systems are equally green. Amongst other things, the amount and source of the energy required is a decisive factor when it comes to the operation’s carbon footprint. Over the years, and because of its distinctive and proven specific […]
Dewatering of sludge from a sewage treatment plant with geotextile tubes
June 1st, 2021
Water is an important resource for people’s quality of life and is indispensable for several uses, including desedentation. However, this resource is finite and available in small quantities in the quality of fresh water, at liquid state and on the surface. Therefore, rivers and lakes, providers of surface water resources, must be treated and kept […]
Geosynthetics are uniquely suited
October 1st, 2019
Geosynthetics are found in the strangest of places. But that just speaks to how versatile and useful they are for a wide variety of applications. Dewatering, energy-site closure, erosion control, reinforcement and stabilization are just a few applications that geosynthetics address in this issue. In addition, many of the geographic areas discussed here are sensitive […]
Recovery of rare earth elements from acid mine drainage using geotextile tubes
October 1st, 2019
By Tom Stephens Acid mine drainage (AMD) has been occurring in the Appalachian region since coal mining began in the early 18th century. Over time, many mines reached the end of their useful life and production ceased or companies went out of business, resulting in AMD discharging from these abandoned mines into native streams and […]

Multilinear drainage geocomposites to filter oil sands tailing slurries
October 1st, 2018
Mining and some energy operations generate large quantities of water-containing tailings. These tailings are made of crushed-rock particles that are deposited in a slurry form. This is the case for coal, tar sand, lead, zinc, gold, silver, copper, molybdenum, nickel, taconite (iron), phosphate, bauxite (aluminum oxide), uranium, trona (soda ash) and potash, for example. There […]
