Abstract:
This invention provides a method for stabilization of flyash and scrubber residues subject to acid and water leaching tests or leach conditions by addition of stabilizing agents and pH reducing agents, such that leaching of lead is inhibited to desired levels. The resultant waste after stabilization is suitable for disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of combined heavy metal bearing materials and wastes subject to acid and water leaching tests or leach conditions by addition of stabilizing agents such that the leaching potential is inhibited to desired levels and the material or waste is free flowing. The resultant material or waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of paint residue subject to acid and water leaching tests or leach conditions by addition of stabilizing agents in slurry or solution form to blast media such that leaching of heavy metals are inhibited to desired levels. The resultant waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of lead smelter slag and matte subject to acid and water leaching tests or leach conditions by addition of stabilizing agents into the smelter feed such that leaching of lead is inhibited to desired levels. The resultant waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of paint residue subject to acid and water leaching tests or leach conditions by addition of stabilizing agents within an OSHA containment building or collection device such that leaching of lead is inhibited to desired levels. The resultant waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of lead bearing slag, matte and bottom ash subject to acid and water leaching tests or leach conditions by addition of pulverized dry and/or dissolvable stabilizing agents such that leaching of lead is inhibited to desired levels. The resultant waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of chromium subject to acid and water leaching tests or leach conditions by addition of solution, reducing, precipitating and stabilizing agents such that leaching of chromium is inhibited to desired levels. The resultant material or waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of combined heavy metal bearing materials and wastes subject to acid and water leaching tests or leach conditions by addition of dry stabilizing agents such that the leaching potential is inhibited to desired levels and the material or waste is free flowing, more permeable, less weight and permits immediate handling and disposal or reuse. The resultant material or waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of flyash and scrubber residues subject to acid and water leaching tests or leach conditions by addition of stabilizing agents and agglomeration effort, such that leaching of lead and regulated heavy metals are inhibited to desired levels. The resultant waste after stabilization and compaction is suitable for disposal as RCRA non-hazardous waste.
Abstract:
This invention provides a method for stabilization of flyash and scrubber residues subject to acid and water leaching tests or leach conditions by addition of stabilizing agents and pressure compaction effort, such that leaching of lead and regulated heavy metals are inhibited to desired levels. The resultant waste after stabilization and compaction is suitable for disposal as RCRA non-hazardous waste.
