| Résumé : |
The process of pickle-tanning results in the significant pollution of wastewaters through the presence of chrome and chlorides. A new process has been studied in order to reduce the negative environmental effect that pickle-tanning causes on leather making. The new process involves a pickle without float and with minimum salt offer as well as the substitution of the inorganic acid by a sulphoaromatic acid. By doing so, the required additions of chrome salt and salt are minimized and this results in high levels of chromium exhaustion in the residual float. When this process is compared to the traditional one, the results obtained indicate that there is a 78 percent reduction in residual float volume, a 93 percent reduction in chlorides content in the effluent and a 95 percent reduction in chrome content in the float. |
