...H. Xie; W. Xu; L. Wang; H. Yan; J. Wu An equivalent analytical model based on time moments is proposed to estimate the properties of landfill composite liners. The service performance of landfill liners composed of a geomembrane layer (GMBL), a geosynthetic clay layer (GCL), and an attenuation...

... of copper(II) (Cu(II)) and zinc(II) (Zn(II)) by three different clay liners. It has been reported that the temperatures in landfills may exceed 150°C due to chemical reactions such as the aluminum production waste reaction (Stark et al. 2012). Rowe (2005) pointed out that the upper part...

...W. Hu; Y. Yu; R. K. Rowe Low-permeability liners are required at the base of municipal solid waste (MSW) landfills to minimize leachate leakage and contaminant migration into groundwater. This paper uses a two-dimensional coupled groundwater flow and contaminant transport model to examine...

...F.B. Abdelaal; R.K. Rowe; R.W.I. Brachman ABSTRACT: The susceptibility of a 1.5 mm thick high-density polyethylene geomembrane to brittle rupture from long-term stress cracking in a simulated municipal solid waste landfill liner is examined. The geomembrane was pre-aged in a leachate at 85°C...

...R.K. Rowe; F.B. Abdelaal; R.W.I. Brachman ABSTRACT: The performance of a 1.5 mm thick high-density polyethylene geomembrane (GMB) in simulated municipal solid waste landfill liners is presented. Accelerated ageing experiments were conducted in geosynthetic liner longevity simulators that allow...

...R.K. Rowe ABSTRACT: This paper discusses the need to adopt a systems engineering approach to the design and operation of municipal solid waste landfills. It discusses how the interaction between the different components affects the performance of the entire system, and how, because...

...B.V.S. Viswanadham; S. Rajesh; P.V. Divya; J.P.

...J.M. Southen; R.K. Rowe ABSTRACT: A fully coupled model is used to simulate the results of large-scale laboratory tests that investigated the non-isothermal behaviour of geosynthetic clay liners in landfill basal liner applications. Results of numerical simulations of the laboratory tests in terms...

Diffusive transport of VOC contaminants through geomembranes in a simulated landfill environment (i.e. in the presence of water vapour) is identical despite the phase they originated from, simplifying the analysis of contaminant transport. The partitioning (sorption) coefficients for PVC were...

Calculations of contaminant impact of dichloromethane, benzene and chloride through GM/CCL/AL and GM/GCL/AL composite liners are reported for a hypothetical municipal solid waste landfill. The geomembrane in conjunction with either the CCL or GCL is very effective at controlling leakage...
