Described herein is a composition for use in a geosynthetic clay liner, the composition comprising particles, at least some of which are discrete particles and each comprise: a compacted swelling clay, the clay having been compacted such that it at least partially surrounds a fluid-loss preventing polymer. Also described herein is a clay liner formed from the composition, a method for producing particles for use in a geosynthetic clay liner, and a method of forming a clay liner.

A method of detecting faults and ensuring integrity of membranes having magnetically functionalized particles, including moving a magnetometer over the membrane to measure at least one magnetic property, mapping the location of the measured properties, identifying anomalies among measured properties including the location of such anomalies, and repairing the membrane at the location where anomalies are identified.

Systems and methods are disclosed for landfill systems, comprising waste, a geosynthetic product, and a layer of foam glass aggregates interposed between the waste and the geosynthetic product.

A flow barrier for wastewater disposal ponds or pits used in oil and gas operations. The flow barrier includes a flake component, a fiber component, and a granular component. The disposal pond flow barrier may prevent the infiltration or leakage of aqueous fluids from the wastewater disposal ponds into the surrounding environment and ecosystems. A process for manufacturing and using the flow barrier in a wastewater disposal pond is also provided.

A cover system for preventing water ingress having a geomembrane layer and a wind-disturbing open-pore layer thereon and defining an asperity extent, said open-pore layer for forming in situ an air-flow turbulence zone between the geomembrane layer and a boundary space proximate the open-pore layer as a transition from turbulent flow of wind in the turbulence zone to laminar flow of the wind remote from the geomembrane layer, said open-pore layer inducing disturbance of a wind flow into and through the layer, whereby a suction force on the geomembrane is disturbingly broken by turbulent wind shear events therein and exerted downward pressure deflections, wherein the wind speed and pressure differential lessen and the geomembrane resists uplift. A method of covering a large area surface with a cover system that resists wind uplift is disclosed.

Systems and methods of the present invention include a method for the treatment of drilling wastes and coal combustion residues, comprising combining at least a first drilling waste with coal combustion residues to form a paste, combining at least a second drilling waste with coal combustion residues to form a compactable fill, and placing the paste and the compactable fill in a landfill. Other embodiments include a method of treating drilling wastes and coal combustion residues, comprising combining at least one drilling waste with a coal combustion residue to form a paste. Further embodiments include containing the paste within at least one geotextile container. Still further embodiments include placing the geotextile container in a landfill.

A pressing-pulling device includes: a pressing-pulling bracket, wherein slotting oil cylinders are symmetrically and vertically mounted on the pressing-pulling bracket, and a piston rod of each of the slotting oil cylinders faces downwardly; a bottom end of the piston rod is connected to a connecting plate, and a through-hole is provided in a middle of the connecting plate; a continuous lifting mechanism is installed in a middle of the pressing-pulling bracket, and a slotting rod is vertically inserted into the continuous lifting mechanism; a lifting ring is installed at a top end of the slotting rod; a bottom end of the slotting rod extends downwardly through the through-hole to connect to a slotting cutter; a locking device is fixed on the connecting plate near the through-hole for fixing the slotting rod.

Systems and methods are disclosed for landfill systems, comprising waste, a geosynthetic product, and a layer of foam glass aggregates interposed between the waste and the geosynthetic product.
