| Résumé : |
A major portion of total dissolved solids (TDS) in leather processing is contributed by common salt (sodium chloride) coming into the effluent during soaking of salt preserved raw hides and skins. If we can prevent or reduce the common salt going into water in the soaking operation, then TDS contributed by sodium chloride can be reduced considerably. TDS reduction is feasible when preserved skins are shaken intermittently in a saturated brine solution. The salt present in the preserved skins is removed and settles to the bottom of the saturated brine solution. The removed salt (from skin) is collected after decantation of the saturated brine solution. The collected salt is washed with fresh saturated brine solution and dried. It can be reused for preservation of skins. The contaminated saturated brine solution is regenerated and recycled again for the next operation. |
