Membrane behavior in clays is a coupled phenomenon that results in solute restriction and
chemico-osmosis. Thus, the containment function of engineered clay-based barriers used …

The purpose of hydraulic barriers, such as geosynthetic clay liners (GCLs), is to isolate
waste liquids from the environment. Bentonite clay is widely used in GCLs because of its …

Extensive research conducted over the past several decades has indicated that
semipermeable membrane behavior (ie, the ability of a porous medium to restrict the …

Chemically modified bentonites are being developed with the aim of preserving low
hydraulic conductivity in the presence of potentially aggressive permeants in pollutant …

The ability of bentonite-based barriers to act as semipermeable membranes that inhibit the
passage of solutes (ions) is well documented. This behavior induces chemico-osmotic liquid …

The potential for membrane behaviour of a chemically modified bentonite (MSB) is
evaluated. Test results showed that MSB exhibited initial membrane behaviour. However …

This paper presents the development of a mathematical and numerical model describing
isothermal contaminant flow of a binary electrolyte through clay soils. It is based on a system …

Contaminant flow parameters are commonly derived from experimental results using
analytical solutions to the well-known advection-dispersion-reaction equation or ADRE. The …

The potential for membrane behaviour of a chemically modified bentonite (MSB) is
evaluated. Test results showed that MSB exhibited initial membrane behaviour. However …

Waste liquids in the environment may result from several sources, eg, uncontrolled dumping
of pure solvents, spills, or infiltration of water through solid waste in landfill disposals …
