| Résumé : |
The beamhouse process is known to contribute around 75% of the wastewater pollution charge in a typical tanning process. Water consumption from raw to the end of deliming process is about 10-12 litres per kg of salted hide, a value which increases in calves and small skins. This process contributes 83% of BOD5, 73% of COD, 60% of suspended solids and 75% of the salinity of the complete process. From the organoleptic point of view the beamhouse processing steps contribute negatively to a tannery's image, mostly because of sulphides. The idea of an alternative oxidative beamhouse process is to recover proteins, reduce the environmental impact of the tannery and generate new opportunities of useful clean by-products, while at the same time reducing the bad smell. This paper considers some practical issues on the industrial implementation of a sulphide free beamhouse process that aims for total water recycling, and the generation of useful by-products. |
