Geosynthetics for CCR, PFAS and energy applications

October 1st, 2021

This issue of Geosynthetics magazine delves deep into two innovative uses of geosynthetic clay liners (GCLs) in very different applications: coal combustion residual (CCR) leachates and per- and polyfluoroalkyl substances (PFAS) mitigation in landfills. We also examine three case studies of energy companies using high-density polyethylene (HDPE) geomembranes for flowback water in water evaporation/recycling ponds. […]

Hybrid geosynthetic clay liners for attenuation of PFAS in landfill leachates

October 1st, 2021

An exponential increase in understanding of the provenance, migration, and fate of per- and polyfluoroalkyl substances (PFAS) is evident over the past decade. The environmental and health concerns from this group of contaminants are well recognized, but they are still evolving with advancing studies. A key property of PFAS compounds at a molecular level is […]

Seaming dissimilar geomembranes Q: I kindly request your technical support in the questions below: A nonpolyethylene geomembrane was used in phase 1 of the tailings dam waterproofing system of a gold mine. For the expansion (phase 2), the use of a high-density polyethylene (HDPE) geomembrane is being evaluated. How can the HDPE geomembrane join the bituminous […]

CETCO launches FLUORO-SORB adsorbent for the remediation of PFAS

June 3rd, 2019

Amid a deeper awareness of the health and environmental impact of per- and polyfluoroalkyl substances (PFAS), CETCO is pleased to announce the launch of FLUORO-SORB® adsorbent, a proprietary, NSF-certified product that effectively treats multiple variants of PFAS.  Unlike other sorbent products that are selective and unpredictable in adsorbing PFAS, FLUORO-SORB adsorbent binds the entire spectrum […]

Geomembranes for canal lining Q: Our company is an international member of the Industrial Fabrics Association International (IFAI). Our government is planning to line their water canals with a geomembrane to prevent water seepage into the soil. We have been approached by many to suggest the most suitable material with specifications to guide them in […]
