Titre : Biodiesel from waste pigskin oil- a two-step process Type de document : texte imprimé Auteurs : Yu Lingyun, Auteur ; Zhao Tiantian, Auteur ; Zhang Xinshen, Auteur ; Zhan Wenxue, Auteur Année de publication : 2009 Article en page(s) : p. 149-151 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : This paper provides a general description of a new continuous biodesel production process, where the transesterification reaction is promoted by two catalysts. The process has been applied on a laboratory scale. The acid value of waste pig oil was greater than 100mgKOH/g oil, but the acid value of biodesel was less than 0.80mgKOH/g oil, and the ester conversion rate was more than 80 percent. The density, residual carbon contents, and acid value of biodesel were met the performance standards of 0# diesel - standard road vehicle oil.

Epilage enzymatiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Il existe de nombreux procédés biochimiques alternatifs à l'épilage au sulfure de sodium, mais ceux-ci ne sont pas reproductibles sans utiliser de sulfures ou de dérivés soufrés à faible dose.
La commission technique tannerie-mégisserie, particulièrement sensible aux problématiques d'épilage des peaux de veaux, a demandé à CTC de mener des travaux sur cette thématique.Note de contenu : - recherche d'une enzyme pure à action kératinolytique

CuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Biogenic means something that is produced or brought about by the action of living organisms. Trees, plants, bacteria, fungi and cows are all examples of organisms that could be said to be producers of biogenic products. The separation of biogenic meat from a biogenic hide is a culmination of the livestock farming and it is at this point that the marketing of a unique material as a biogenic material must be remembered. It is not only a biogenic material, but it is a material that should be used (al long as humans consume meat). Note de contenu : - Is it all biogenic ?

Titre : Biokinetics and toxicity assessment of tannery wastewater using batch reactor system Type de document : texte imprimé Auteurs : R. A. Ramanujam, Auteur ; M. Mariappan, Auteur ; R. Ganesh, Auteur Année de publication : 2004 Article en page(s) : p. 468-473 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The design of an activated sludge process involves the establishment of fundamental reaction kinetics using batch laboratory scale biological oxidation system and integration of the batch kinetics with mixing theory to predict the performance of a continuous process. Batch tests can be used successfully for the determination of kinetic parameters and toxicity of wastewater. The results obtained in the present study show that pre-treated tannery wastewater is not toxic to microorganisms. The design criteria evolved using the batch study were loading rate (0.09 BOD/mixed liquor volatile suspended solids) and hydraulic retention time (> 24 hours) for meeting the effluent BOD standard. These design values suggest that the extended aeration system is the most appropriate activated sludge treatment method for tannery wastewater. The half-velocity constant (Ks) evaluated was in the range 245 - 312 mg/l on BOD basis and 963-1138 mg/l on COD basis. Ks defines the substrate uptake characteristics. The relatively higher value of Ks for tannery wastewater compared to domestic wastewater indicates that substrate removal is slower and hence longer retention time is required for complete biodegradation of tannery wastewater. The regression analysis of the batch experimental data in a coordinate system InS/S0 versus tXa for the determination of specific rate constant (KE) resulted in a satisfactory correlation coefficient (r = 0.99). Estimating biokinetic constants for tannery wastewater according to a first order reaction using a batch reactor was satisfactory.

Titre : Biological nitrogen control - a comparison of methods Type de document : texte imprimé Auteurs : Curtis C. Panzer, Auteur Année de publication : 1982 Article en page(s) : p. 149-160 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The EPA has identified extended aeration as a method "appropriate" for the biological treatment of tannery wastes. In this paper a conventional extended aeration (nitrification) system is contrasted with an extended aeration system designed for combined nitrification and denitrification (N/D) now under development at the Eastern Regional Research Center for secondary treatment of cattlehide tanney wastes. Parallel laboratory scale treatment studies were conducted, with each system held at 18-22°C and a sludge residence time of 20 days. Pretreated unhairing effluent was used as the model waste. Results indicate that in order to meet EPA proposed best available technology (BAT) limitations for chemical oxygen demand (COD) with either system, it is likely that a physical-chemical pretreatment of the unhairing effluent and other streams will be required.
The combined N/D system demonstrated the capacity to handle a nearly 40 percent greater COD loading rate than the conventional system, while producing the same degree of waste removal in terms of COD and TKN (total Kjeldahl nitrogen).Note de contenu : INTRODUCTION : Experimental influent
