The elimination of chromium in the treatment of tannery industrial wastewater

Abstract

Presents the findings of a study conducted to examine the efficiency of the combined anaerobic‐aerobic reactors for the treatment of three different tannery industrial wastewaters, focusing on the fate of chromium and other associated metals. Examines elimination rates of such metals with respect to each successive treatment process. Discusses the correlation between the chemical characteristics of the wastewater influent and effluent along with the level of heavy metals in such wastewater and the produced sludge. Confirms that the use of such sludge in agriculture should be restricted and recommends the recovery of Cr from the tanning sludge.
