Anaerobic Digester Designs: Critical Liner Issues to Avoid Whales was presented at GeoAmericas 2016 (10 – 13 April 2016, Miami) ABSTRACT In 2014, shortly after being placed in service, one of two geomembrane-lined and covered anaerobic digesters generated extensive whales (cover uplift). Attempts to remove the apparent gas from under the cover were made unsuccessfully until it was realized t... »
Repairing of a Geomembrane Lining System (GLS) Used for Raft Waterproofing of Civil Engineering Buildings
Repairing of a Geomembrane Lining System (GLS) Used for Raft Waterproofing of Civil Engineering Buildings was presented at GeoAmericas 2016 (10 – 13 April 2016, Miami) ABSTRACT The use of a geomembrane lining system (GLS) as tanking system for civil engineering buildings is difficult, especially when the GLS cannot be visited for maintenance in case of waterproofing deficiency during its ser... »
Geosynthetic Closure System Allows Local Government Municipality to Turn Landfill into Solar-Powered Generation Facility
Geosynthetic Closure System Allows Local Government Municipality to Turn Landfill into Solar-Powered Generation Facility was presented at GeoAmericas 2016, Miami ABSTRACT: In 2011, the Connecticut Resources Recovery Authority, now known as the Materials Innovation and Recycling Authority (MIRA), identified alternative landfill capping systems, including an Engineered Synthetic Turf System (EST) as... »
ABSTRACT Approved alternative final cover systems for landfills – and now coal ash ponds and piles – include geosynthetic systems along with exposed geomembrane in some cases. Exposed geosynthetic materials are susceptible to damage from environmental factors such as wind, ultraviolet (UV) radiation, and thermal oxidation. Field UV exposure and effects measurements have become available to c... »
ABSTRACT Since the early beginnings, geomembranes have continuously evolved to meet the more and more demanding needs of the different industries. Project requirements and environmental constraints have rendered what was acceptable leakage over half a century ago, obsolete in today’s world. In 1997, the Geosynthetic Research Institute published a now worldwide recognized standard for HDPE geomembr... »
Performance of Ethylene Vinyl Alcohol (EVOH) Geomembranes for the Containment of Organic Solvents Versus Traditional Geomembranes
ABSTRACT As the geosynthetic industry continues to find ways to reduce leakage through holes, the molecular diffusion of contaminants through geomembranes becomes more significant. Since around 2009, new high barrier geomembranes containing at least one thin layer of ethylene vinyl alcohol (EVOH) have been proposed and are providing another class of geomembranes to the industry. This new class of ... »
Effect of Compatibilizing Agent on the Mechanical, Thermal, and Barrier Performance of HDPE Nanocomposite Membranes for Application as a Geomembrane
ABSTRACT: The emergence of new resource development technologies and industrial processes combined with increased concerns for the environment bring new challenges as well as new opportunities to geomembranes. Nanocomposites give an innovative method to increase geomembrane mechanical, thermal and barrier performance. For instance, clay nanoparticles dispersed in the polymer matrix appear to be a ... »
ABSTRACT: Chlorine has the third highest electronegativity of all chemical elements (after fluorine and oxygen); thus, chlorine is a very strong oxidizing agent. This paper investigates the rate of antioxidant depletion from different geomembranes immersed in chlorinated water at 85oC. Free chlorine is introduced to the incubation solution by mixing sodium hypochlorite with deionized water with a ... »
