Treatability Study of Tannery Effluent by Enhanced Primary Treatment
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 1
Abstract
Abstract: This project work has been focused on the study of enhanced primary treatment of tannery effluent by coagulants which includes analysis of physico-chemical parameters of tannery effluent as well as the treatment efficiency of alum, ferric sulphate and their combination (alum + ferric sulphate). Sample collection and analysis were performed using standard methods for the examination of water and wastewater (1998). Tannery effluent has been treated with the coagulants. The influences of pH and coagulant dosages were studied. Conditions were optimized according to the pollutant removal efficiencies measured in terms of reduction in concentration of total suspended solid (TSS), biological oxygen demand (BOD5), chemical oxygen demand (COD) and Chromium(Cr). The reduced concentration of pollutants have been analyzed with industrial effluent discharge standards to determine the efficiency of coagulants in enhanced primary treatment of tannery effluent.
