From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...
Fly Ash for use in the Stabilization of Industrials Wastes
Fly ash and other coal combustion by-products are used in the stabilization of industrial wastes. This paper describes the various types of fly ashes, the mechanisms of strength development,...
Properties of Solidified HLW and Their Changes Under Storage and Disposal Conditions
The paper gives the results of the studies of the properties of different solidified high level waste (HLW) - vitreous (phosphate and borosilicate) composites as well as glass ceramics...
Interim Storage of Solidified High Level Wastes
Indian approach to the problem of interim storage of vitrified high level wastes, indicating design philosophy adopted for air cooled vault at Tarapur has been described. Important design...
A Compact Nonlinear Solution Method for Two Phase Stefan Problems
Finite element formulations for fluid filling problems with solidification are derived using previously developed unified transformation techniques. The nonlinear formulation for two phase...
A Phenomenological Approach to Physico Chemical Phenomena Coupled with Damage in Massive Concrete
This paper presents the first experiments which have been done to support the bases of a thermomechanical model coupled with damage and to identify the characteristics parameters needed...
Chemical Treating Agents for Oil Spill Response?Recent Research Results
Laboratory effectiveness tests have been developed for four classes of spill-treating agents; solidifiers, demulsifying agents, surface-washing agents and dispersants. Currently-available...
Programmatic Challenges and the Value of Testing on the West Valley Demonstration Project's Vitrification Facility Design
The primary objective of the West Valley Demonstration Project (WVDP) is the solidification of approximately 2.1 million liters (560 thousand gallons) of high-level waste (HLW) which resulted...
No Feet of Clay
The methods of dealing with hazardous waste are evolving. At Superfund sites, for instance, excavation and removal was once the popular choice for treating pollutants, but stabilization...
Design of Solidified/Stabilized Sludge Landfills
Rehabilitation of highly moist, compressible, and heavy metal-containing wastewater treatment sludges for final disposal in a landfill setting requires consideration of several factors....
The Use of Polyurethane Grouts and Grout Tubes
Most polyurethane grouts used for seepage control are one-component, and water activated. They are prepolymers of a polyisocyanate with a polyol. Some of the polyurethane grouts use an...
EPA: Siting Permanent Solutions
EPA's SITE (Superfund Innovative Technology Evaluation) program is entering its third year. It is designed to speed up hazardous waste treatment technology. The program helps...
A Watery Grave
Subseabed disposal may be the most acceptable means of dealing with radioactive wastes. Land disposal sites are difficult to find and politically difficult to use. Little research has...
Field Scale Solidification/Stabilization of Hazardous Wastes
The selection of appropriate remedial action measures only takes place after a full evaluation of all feasible alternatives. An alternative to off site disposal is solidification/stabilization...
