The use of geomembrane plastic in salt production has been effectively used since 2012. Geomembrane can increase the growth by almost 100%. is a relatively thin, interconnected polymer sheet. repeatedly for approximately two years and exposed to sunlight. This research was conducted determine traces components dried sun using drying mat. UV-Visible detect presence functional groups FTIR spectro...

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...

landfill is the major method of solid waste disposal in developing countries. to protect soil andgroundwater from contamination, anti-seepage systems have to be installed in landfills. however, during theconstruction of anti-seepage system, many factors can result in holes in geomembrane liners. for the purpose of improving construction quality, the construction company needs to find the leaks ...

This paper presents the construction of multi-layer geosynthetic containment systems as part improvements to a stormwater management system mitigate groundwater contamination at coal combustion residual landfill in southeastern USA. The consisted lining perimeter ditch and sedimentation pond contain ash sediments minimize infiltration into groundwater. A composite liner comprised HydroTurf synt...

iran has limited water resources that require preservation and reducing water loss from reservoirs, especially in arid and semi arid regions. there are a number of methods available for to control water loss from reservoirs and canals. concrete linings in water reservoirs and ponds are durable, but their efficiency is limited. geomembrane sheets are another method of controlling leakage from wa...

Geotextile layers are arranged on and below the geomembrane to prevent from being punctured damaged. The geotextile not only plays a role in physical protection, like anti-puncture but also makes great difference mechanical properties of geomembrane’s air expansion deformation. In this paper, bulging deformation is simplified as spherical under ring-restrained conditions. Using special test equ...
