RISBacterial Leaching of Metals from Tannery Sludge by Indigenous Sulphur-Oxidizing Bacteria—Effect of Sludge Solids Concentration
Publisher: American Society of Civil Engineers
Abstract: An investigation on the effect of sludge solids concentration on bioleaching of Cr(III) and other metals from tannery sludge by indigenous sulphur-oxidizing bacteria was carried out. The sludge solids concentrations ranged ...
Laboratory Pilot Test of Chromium (III) Isolation from Acid Extract of Tannery Sludge
Publisher: American Society of Civil Engineers
Abstract: High concentrations of Al, Fe, Ca, Mg, and Zn in the tanning agent are detrimental to the properties of tanned leather. To recycle the Cr(III) from the tannery sludge to the tanning agent, these five metals must be removed ...
Chromium(III) Isolation from Acid Extract of Tannery Sludge
Publisher: American Society of Civil Engineers
Abstract: High concentrations of Al, Fe, Ca, Mg, and Zn in the tanning agent are detrimental to the properties of tanned leather. To facilitate removal of chromium from the tannery sludge and recycle to the tanning agent, these five ...
Effect of Sulphur Concentration on Bioleaching of Cr(III) and Other Metals from Tannery Sludge by Indigenous Sulphur-Oxidizing Bacteria
Publisher: American Society of Civil Engineers
Abstract: An investigation on the effect of elemental sulphur concentration on bioleaching of Cr(III) and other metals from tannery sludge by sludge indigenous sulphur-oxidizing bacteria was performed. Elemental sulphur concentrations ...
