ABSTRACT:
A process and apparatus for transforming contaminated material such as liquid wastewaters, into a solid and chemically stable composition which can be utilized as construction material, or which is safe for land disposal. The contaminated material is blended with solidification agents such as cement or lime until substantial amalgamation of the agent and material is completed. The contaminated material is contained within microencapsulation matrices which physically isolate the contaminated material from the environment. The apparatus is transportable and can be brought to the contamination site to transform the contaminated material into the solid and chemically stable composition.
