Tannage Résumé : Reuse of pickling wastewater after treating it electrochemically has been studied. Pickling wastewater has been neutralised to pH 7.0 and subjected to electrooxidation. electrooxidation has been carried out using graphite electrodes at a current density of 0.012 A/cm2 for 2 hrs. Pickling wastewater has been analysed prior to and after the treatment. Treated wastewater has been reused and the cycle continued for seven times. The pickled pelts were chrome tanned and further converted into crust leathers. Shrinkage temperature, chromium uptake and chromium distribution of wetblue were tested. Crust leathers were tested for physical chrateristics. Characteristics of treated pickling wastewater indicated that electrooxidation reduced the pollution load in terms of COD and TKN significantly. Results indicated that the recycling did not influence the characteristics of wetblue and crust leathers.
