Antioxidant Depletion and Service Life Prediction for HDPE Geomembranes Exposed to Low-Level Radioactive Waste Leachate
Antioxidant depletion was evaluated in high-density polyethylene (HDPE) geomembrane (GM) coupons immersed in radioactive synthetic leachate (RSL) representative of leachate in low-level radioactive waste (LLW) disposal facilities operated by the U.S. Department of Energy’s environmental restoration programs. Depletion was assessed at four temperatures (25, 50, 70, and 90°C). Comparative tests w...
متن کاملThe Tension and Puncture Properties of HDPE Geomembrane under the Corrosion of Leachate
To investigate the gradual failure of high-density polyethylene (HDPE) geomembrane as a result of long-term corrosion, four dynamic corrosion tests were conducted at different temperatures and durations. By combining tension and puncture tests, we systematically studied the variation law of tension and puncture properties of the HDPE geomembrane under different corrosion conditions. Results sho...
متن کاملDiffusion of multiwall carbon nanotubes (MWCNTs) through a high density polyethylene (HDPE) geomembrane.
The new applications for carbon nanotubes (CNTs) in various fields and consequently their greater production volume have increased their potential release to the environment. Landfills are one of the major locations where carbon nanotubes are expected to be disposed and it is important to ensure that they can limit the release of CNTs. Diffusion of multiwall carbon nanotubes (MWCNTs) dispersed ...
متن کاملEffect of Geomembrane Ageing on the Diffusion of VOCS through HDPE Geomembranes
This paper describes the migration of four commonly found volatile organic compounds (VOCs) in landfill leachates e.g., benzene, toluene, ethylbenzene, and xylenes through 1.5mm thick high density polyethylene (HDPE) geomembranes. Diffusion and sorption tests were conducted at room temperature (i.e., 22C) on both unaged and 13-month aged geomembrane samples. Ageing of geomembrane was carried ou...
متن کاملAnalysis of Environmental Applicability of HDPE Geomembrane by Simulated Applicability Testing for Waste Containment Construction
Geosynthetic separation boxes made from recycled polymeric materials were designed to increase the waste landfill amount and develop the hydraulic performance in steep slope sides in the waste landfills. To evaluate the advantages of these geosynthetic separation boxes, index tests were conducted in order to compare the geonet composites and geosynthetic separation boxes. The tensile strength r...
