The elimination of chromium in the treatment of tannery industrial wastewater
نویسنده
چکیده
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. Introduction

متن کاملScope of biological treatment for composite tannery wastewater
Tannery wastewater is heavily polluted containing appreciable biodegradable matters as well as inorganic substances like chromium, sulphide, chloride etc. Thus the composite tannery wastewater appears to be incompatible for direct biological treatment .Wastewater emanated from various sub-processes of tannery operation showed variable characteristics and also differential treatability. The pres...
