Effect 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 کاملAgeing resistance of HDPE-geomembranes – Evaluation of long-term behavior under consideration of project experiences
A question frequently asked about HDPEgeomembranes is “how long will they last?” After more than 30 years of experience with exposed (weathered) HDPE-geomembranes, the authors address the question from the designer’s view point. The engineer needs to know, if available test methods tell us how long the geomembrane will last, and which properties must be specified and what are the minimum accept...
متن کاملAntioxidant 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...

15 صفحه اولModeling benzene permeation through drinking water high density polyethylene (HDPE) pipes.
Organic compounds such as benzene, toluene, ethyl benzene and o-, m-, and p-xylene from contaminated soil and groundwater may permeate through thermoplastic pipes which are used for the conveyance of drinking water in water distribution systems. In this study, permeation parameters of benzene in 25 mm (1 inch) standard inside dimension ratio (SIDR) 9 high density polyethylene (HDPE) pipes were ...
