Environmental impact evaluation of typical beamhouse processes in leather manufacture based on wastewater settleability / Qiang He in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. C, N° 12 (12/2005)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. C, N° 12 (12/2005) . - p. 473-480 Titre : Environmental impact evaluation of typical beamhouse processes in leather manufacture based on wastewater settleability Type de document : texte imprimé Auteurs : Qiang He, Auteur ; Bi Shi, Auteur ; Danhong Sun, Auteur ; Kai Yao, Auteur Année de publication : 2005 Article en page(s) : p. 473-480 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure 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.

Biosensor based toxicity dissection of tannery and associated environmental samples / Mwinyikione Mwinyihija in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. C, N° 12 (12/2005)

Tannage Résumé : Kenyan tannery and associated environmental samples were selected for ecotoxicological assessment. A tool-kit of techniques was developed, including whole cell biosensor and chemical assays. A luminescence based bacterialbiosensor (Escherichia coli HB101 pUCD607) (via a multi-copy plasmid) was used for toxicity assessment. Samples were manipulated prior to biosensor interrogation to identify the nature of the toxic contaminants. Untreated samples (before any manipulations) showed a strong toxic effect at the discharge point in comparison to other sampling points. Sparging was used to identify toxicity associated with volatile organics. The toxicity of contaminants, removed by treatment with activated charcoal, was identified for all the sampling points except for those upstream of effluent discharges. Filtration identified toxicity associated with suspended solids. Changes in availability of toxic contaminants due to pH adjustment of most samples from the tannery effluent treatment pits were also associated with the extreme pH values (4.0 and 8.0). The approach used has highlighted the complexity of toxic pollutants in effluent from the tanning industry. Dissection of toxicity points suggests possible remediation strategies for effluents from the tanning industry.
