Studies on Treatment of Tannery Industry Effluent by Coagulation Process

Abstract

The tannery industry is well known as a high consumer of water. It can newlinecreate heavy pollution from effluents containing high levels of salinity, organic newlineloading, inorganic matter, dissolved and suspended solids. The presence of residual newlineimpurities such as chromium, COD, color, turbidity, organic material etc in tannery newlineindustry effluent is aesthetically undesirable and causes problems for the aquatic newlinebiosphere due to the reduction of sunlight penetration and depletion of the dissolved newlineoxygen. Wastewater characterization is an important step in designing effective newlinetreatment facilities for industrial wastewaters. This is especially true for tanneries newlinewhich exhibit significant differences in their production processes generating newlineeffluents of unique and complex nature newline
