| Résumé : |
The traditional leather industry is far from sustainable. Therefore, many new leather-making processes, so called 'cleaner technologies', have been proposed to reduce the levels of pollutant emission. The objective of this study is to make an environmental impact evaluation of such processes not only based on the quantity of wastes generated but also on the wastewater treatability. This paper is mainly concerned with the settleability of wastewater. Such an evaluation might be of great significance due to the enormous amount of wastewater and increased treatment costs. The research is typified by enzyme assisted soaking and unhairing (ESU) processes that are encouraged in beamhouse processes for protecting the environment. The chemical sedimentation behavior of ESU wastewater and the wastewater generated by conventional soaking and unhairing (CSU) processes are described and compared with each other. It was found that ESU wastewater showed better sedimentation property than CSU wastewater, indicating that the enzyme assisted soaking and unhairing processes have environmental friendliness in terms of wastewater settleability. |
