Leakage analysis through composite liners in landfills
2015Liner system reliability is of key importance for landfill risk mitigation. There are many design recommendations and standards from several environmental agencies around the world. Among them, single liners and composite liners designs are frequently used. In this article, leakage through single and composite liners was determined in order to evaluate

Preliminary results of composite liner field performance study
Geotextiles and Geomembranes, 1997Abstract This paper presents preliminary results of a study of the field performance of composite liners. The purpose of the study is to evaluate the ability of composite liners to contain municipal solid waste (MSW) leachate. The paper presents data for double-lined MSW landfills having composite top liners consisting of a geomembrane (GMB) upper ...

Transport of organic contaminants within composite liner systems
Applied Clay Science, 2002Abstract Composite liners (a geomembrane in intimate contact with a mineral liner) are frequently used to line landfills and contaminated sites. It is therefore very important to characterise the behaviour of these systems even under extreme conditions.

Modeling Volatile Organic Compound Transport in Composite Liners
Journal of Geotechnical and Geoenvironmental Engineering, 2012AbstractData from bench-scale composite liner experiments were compared with predictions made with two models, a finite-difference model and a semianalytical model, used to predict volatile organic compound (VOC) transport through composite liners. Transport parameters for the geomembrane and clay for five common VOCs were measured independently and ...

Numerical study of advective flow through composite liners
Environmental Geotechnics, 2016This study presents numerical simulations of advective flow through a composite geomembrane geosynthetic clay liner (GMB-GCL). In the past, GCLs were considered homogeneous materials, but they actually consist of a special layered composite structure that combines two types of materials, geotextiles and bentonite, which are connected together by ...

Composite landfill liner design with Ankara clay, Turkey
Environmental Geology, 2005This study presents an overview of the geotechnical properties of the clayey soils, referred to as “Ankara clay”, at two sites of the Ankara region in an attempt to design a landfill profile composed of a high density polyethylene (HDPE) geomembrane/clay composite liner through the Hydrologic Evaluation of Landfill Performance (HELP) model and the ...

Using cavity liners with direct posterior composite restorations.
Compendium of continuing education in dentistry (Jamesburg, N.J. : 1995), 2006Cavity liners have traditionally been used in direct and indirect restorations for purposes such as promoting reparative dentin and neutralizing acids. Today, liners are used when resin composites are used as the restorative materials on the posterior teeth, but for a different reason.
