Anaerobic digestion treatment of Tannery waste water

Abstract

In this article an attempt is made to study the highly complex and is characterized by high content of organic, inorganic and chromium, suspended solids and dissolved solids present in Tannery waste water. Treatment of tannery waste water is carried out by physical, chemical, biological or the combination of these methods. Up flow anaerobic sludge Banked Reactor (UASB) exhibited better performance for treating high strength tannery wastewater effectively, compared with conventional reactors. Both aerobic and anaerobic processes are employed for the treatment of tannery wastewater.
