Tannage Résumé : The effect of incremental increases in concentration of sulfates on anaerobic digestion was investigated using a laboratory-scale Upflow Anaerobic Sludge Blanket (UASB) reeactor fed semi-continuously with a synthetic wastewater. A concentration of up to 6000mg/l SO42- was found to have no effect on an acclimatized anaerobic digester with the exception of a decrease in the methane yield. The sulfides formed as a result of microbial sulfate reduction were distributed between soluble sulfides and hydrogen sulfide in the biogas. Precipitation of heavy-metal sulfides also occured in the digester. These results suggest that the concentration of sulfates and sulfides present in tannery wastewaters would be insufficient to cause failure of anaerobic digesters.

The effect of sodium chloride on anaerobic digestion / C. A. Jackson-Moss in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXIV (Année 1989)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXIV (Année 1989) . - p. 266-271 Titre : The effect of sodium chloride on anaerobic digestion Type de document : texte imprimé Auteurs : C. A. Jackson-Moss, Auteur ; J. R. Duncan, Auteur ; Desmond R. Cooper, Auteur Année de publication : 1989 Article en page(s) : p. 266-271 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The ability of anaerobic microbial populations to adapt to high sodium chloride concentrations was investigated. It was found that a sodium chloride (NaCl) concentration of up to 17.000 mg/L had no inhibitory effects on the anaerobic digestion process. There were no notable differences in digester performance relative to a control with the exception of an increase in the methane content of the biogas. These results suggest, therefore, that the concentration of NaCl present in tannery wastewaters, which ranges from 2.500 to 12.500 mg/L, would have no significant effect on an acclimatized anaerobic digester treating these wastes.

The effect of trivalent chromium on anareobic digestion / C. A. Jackson-Moss in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXIII (Année 1988)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXIII (Année 1988) . - p. 389-395 Titre : The effect of trivalent chromium on anareobic digestion Type de document : texte imprimé Auteurs : C. A. Jackson-Moss, Auteur ; J. R. Duncan, Auteur Année de publication : 1988 Article en page(s) : p. 389-395 Note générale : Biblio. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The effect of trivalent chromium an anaerobic digestion was investigated using a synthetic waste containing glucose as the organic carbon source. It was found that an influent concentration of 5000mg/l trivalent chromium could be tolerated by acclimatized methanogenic bacteria. However,if the concentration in the synthetic waste was further increased, inhibition of the methanogens resulted, with a corresponding decrease in degester performance. These results suggest,therefore, that the concentration of trivalent chromium present in tannery effluents and sludges,which ranges from 1 to 2500 mg/l would have no significant effect on an acclimatized, stable anaerobic digester treating these wastes.
