In mining, due to the high environmental responsibility and load supported, geomembrane-soil interface must guarantee parameters (such as friction angle adhesion) that contribute stability of barrier system. The use a textured High-Density Polyethene (HDPE) geomembrane, known structured guarantees uniformity in asperity height manufacturing process (flat-die). present work presents results dire...

The interfacial friction performance of the liner system has an important influence on overall stability modern landfills, but interface using conventional geomembranes may have problems such as shear failure and slip along system. Accordingly, concept a ribbed geomembrane was proposed. Based laboratory model tests, variation laws p–s curves additional stress sand were studied under different v...

Recently, biodigesters have attracted much attention as an efficient alternative for energy generation and organic waste treatment. The final performance of a biodigester depends heavily on the quality its building process selection raw material: geomembrane. geomembrane is coat that covers used to control migration fluids. Therefore, proper geomembrane, in terms thickness, resistance, flexibil...

Abstract Seawater is used to produce salt. For 10–15 years, geomembrane plastic has been in salt fields Indonesia prevent contamination and increase quality productivity. However, it unfortunate that currently, seawater polluted by waste, which degraded gradually into small pieces about <5 mm size called microplastics. In addition microplastics, also heavy metals. Previous research indicated...

Composite liners with a geomembrane and either a compacted clay or a geosynthetic clay liner are widely used to minimize leakage from landfills and other containment systems such as leachate lagoons. While much work has been done to quantify the rates of leakage, few papers assess the impact of this leakage on groundwater quality. This is particularly important for organic contaminants because ...
