| Résumé : |
A low cost computer-controled system to recycle chromium containing liquid and solid waste from the tanning industry is described. The mathematical model for the recycling technology is based on the chemical-physical engineering description of the heterogeneous kinetics of the process. Regressive analysis was used to determine values for the parameters in each kinetic equation from experimental data. The idea for the recycling technology lies in using the reaction of non-environmentally friendly chromium containing liquid and solid wastes and creating new products that are not toxic and can be used in other industrial applications. The proposed model was used for a simulation test and for an optimum calculation in connection with minimum operating costs of the recycling technology. The process, including the computer control system, was demonstrated with laboratory equipment using real chromium-containing liquid and solid waste obtained from a beam house. |
