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.

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 […]
