BINDING AGENTS AND REAGENTS USED IN THE STABILIZATION/SOLIDIFICATION PROCESSES OF WASTE MATERIALS

摘要

This paper provides the possibilities of selection the additives depending on the type of waste material. Additives of inorganic origin have the highest use because they meet the required physical and chemical characteristics of the S/S materials.Using the technological process of stabilization/solidification (S/S) and corresponding additives, the waste material is transformed into inert material independently of the individual values of metal solubility or the components in the waste. Also of great importance is the fact that some physical or chemical parameters of solidified waste material (permeability, resistance to compression) can be easily controlled by selection of chemical additive and its share in the mixture (waste/additives). The process of S/S has a reasonable use in liquid waste or waste with a high content of liquid phase with impossible disposal on the landfills without prior treatment.
