ABSTRACT

 

Manufacturing of leather, leather goods, leather boats and fur produces numerous bye products, solid waste, high amounts of waste water containing different loads of pollutant and emitions in to the air. The uncontrolled release of tannery effluent to natural water bodies increases health problems for human beings and environmental pollution. Hence, the contaminants have to be removed in order to avoid significance environmental impacts. This paper presents the results obtained from pilot scale study developed in the tannery district of Erode in Tamil Nadu (India). The present study also aimed at evaluating the reuse of waste water produced in the retanning process. For this purpose, the pilot scale study based on the combination of the activated sludge process and reverse osmosis process was considered. From the result it can be seen that the combination of sludge process (Biological process) with membrane system showed satisfactory results in case of waste water treatment reuse and recovery in the tannery industry.
