Tannage Résumé : During chromium tanning of wooly sheepskins, weathered areas of the wool take up chromium and the resultant green colour persists through to the finished product. Testing of skins using both recycled bath and single-bath situations after additions of aluminium sulphate to the tanning bath has shown reduction of the chromium content and colour of the wool on the tanned skins. Limited physical testing of these skins has aslo shown no change in properties tested compared with skins tanned without aluminium added, with the exception of lower tear strength.

Titre : Reduction of tannery waste volume through countercurrent reuse of process streams Type de document : texte imprimé Auteurs : M. Komanowsky, Auteur ; G. E. Senske, Auteur Année de publication : 1982 Article en page(s) : p. 206-223 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Tannery effluents are expensive to treat - biologically because of their high waste loads and physiochemically because of their large volumes. Countercurrent reuse of all prechrome processing streams in a manner similar to classical multistage leaching drastically reduced the effluent volume generated in the preparation of hides for tanning (to between 1/10 and 1/20 of the present volume). Pretreatment of process streams was limited, consisting only of ammonia recovery from the bating solution, sludge separation from the unhairing effluent, and pH adjustement of the post-relime and post-bate wash waters. The resulting leathers were comparable in physical strength and visual appareance to those made conventionally , although they had a slightly less uniform coloration when dyed than conventionally produced leather. This problem was partially eliminated by adding detergent, and by increased mechanical action. This report contrasts countercurrent with conventional processing in terms of the chemical composition of the hides and of the effluents at corresponding processing stages. The benefits derived from this processing approach with regard to pollution are also discussed.

Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The chrome tanning process is the most popular tanning method but it results a considerable discharge of chromium to the wastewater. Various processes have been developed to increase the up-take of chromium by the hide with success, but there remains a major chromium discharge to the wastewater.
The wastewater from the tanning process can be reused directly or indirectly but these recycling processes can present problems related to the accumulation of undesirable substances (salts, fat, protein, etc.) and irregularities from batch to batch. The present work is devoted to the development of a direct recycling process that associates a high chromium up-take process with recycling to the pickling bath and then disposal of this bath after pickling.
A reduction of the chromium offer to between 4.5% and 5.5% is achieved, against typical values of between 7% and 8%. Good results are obtained for chromium discharge to the wastewater especially when the splitting is done in the lime state where values of chromium about 50 mg/L are obtained.Note de contenu : - Initial high exhaustion tannage

Titre : Reduction of water demand and treatment cost in tanneries through reuse technique Type de document : texte imprimé Auteurs : Mariliz Gutterres, Auteur ; J. O. Trierweiler, Auteur ; L. S. Severo, Auteur ; P. M. Aquim, Auteur ; J. B. Passos, Auteur Année de publication : 2008 Article en page(s) : p. 138 - 143 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Tannery industries employ great amounts of water; because most of their processes occur in an aqueous medium. This leads to the generation of high wastewater flowrates which will have to be treated due to the relatively high concentrations of some pollutant species. The attending paper presents this problematic throughout a case study in Rio Grande do Sul, state of Brazil. It establishes the water consumption in each stage of leather processing. In order to achieve the reduction in the total water consumption, herein it is proposed the water reuse technique in some stages of the process. Experimental results, on industrial scale, are shown so that the methodology is demonstrated to be successful. Water reuse reduces the load of the wastewater treatment plant as well as it reduces the costs. Research on water demand in tanneries defines water consumption for each stage: beamhouse, tanning and pos-tanning operations. It is known that tanneries make use of water in an uncontrolled manner, usually higher than actually would be necessary. Additional, most of the stages use fresh waters from artesian wells or from rivers. Recycling technique is current in liming operation. This paper shows that reuse and recycle techniques could be applied for other operations. Alternatives of water reuse were evaluated through the analysis of the process's wastewater to estimate the concentration of some contaminant parameters. The study was carried out on industrial scale. These parameters are indicators to evaluate the water quality according with the objectives of the reuse system. During analysis, it was tested reuse in the pre-deliming and deliming stages, using 100% of the effluent from bating washing. The parameters analyzed in the process's wastewater with reuse practice did not present any considerable difference when one compared with the conventional process. It demonstrates the viability of reuse practice in tannery industry. This study is of great importance to the environmental and to tannery industry, because the reuse technology aims at a solution to water minimization that results in the maximum environmental protection and cost reduction.
