Abstract

The technologies of solidification/stabilization (S/S) are used as final stages of residue treatment, before its final disposition. The objectives are to improve the physical characteristics and the handling of the residue to decrease the superficial area, hindering the pollutants transfer. These objectives are quantified by leaching tests, regarding environmental aspects. For the final disposition of sludge generated by industrial laundries in the area of Maringá - state of Paraná - Brazil, it will be incorporated to the cement by S/S, aiming its final disposition and turning it into raw material for future use. In this work the solidified material is evaluated regarding S/S, through leaching. With the results of the leaching tests, basing on an adaptation of NBR10005/87-ABNT norm, the variation of the concentration is taken into account in function of the time and data are generated for mathematical modeling, for obtaining the adjusted modified diffusion coefficient. Results show that the main mechanism in the leaching tests for the metals Fe and Al is the diffusion
