A method for economically separating chemical contaminants such as volatile organic chemicals (VOC's) and polychlorinated biphenyls (PCB's), even if the contaminants are present at low concentrations, from inert materials such as soils or sludges, comprising subjecting inert materials contaminated with chemical compounds to a temperature effective to volatilize the contaminants but below incineration temperature, with continuous removal of evolved vapors, for a period of time sufficient to effect the desire degree of separation of contaminants. The evolved vapors may be subjected to catalytic oxidation to destroy the volatilized chemical compounds.

Process and apparatus for separating organic contaminants from

A method for stabilizing a mercury-containing waste comprising adding elemental sulfur and cement kiln dust to the waste in amounts effective to reduce the amount of leachable mercury to an environmentally acceptable level.

Stabilization of mercury-containing waste

A waste material compression tester is provided and having a reservoir or chamber for holding a sample of waste material containing liquid, a pressure source to apply pressure to the waste material under a pre-set pressure and a predetermined time period and a detector to indicate whether liquid was exuded from the waste material after the pressure is removed.

Waste material compression tester

A method for treating hydrazine-fuel contaminated wastewater in which hydrazine, monomethyl hydrazine, unsymmetrical dimethyl hydrazine and dimethylnitrosamine pollutants are effectively decomposed at a controlled pH of about 5 by an ultraviolet induced chlorination treatment of the wastewater.
