Industrial sector is understood to be one of the major offenders in polluting environment particularlywater among others. Sugar industry is one among the agro-based industry releasing high organicpollutants rich in BOD. Though conventional treatment methods have been employed in treating sugarindustry effluents at varied degrees, they come with their own setbacks. In this direction naturalcoagulants are explored and evaluated for their potential and efficiency towards treating sugar industryeffluents. The process of coagulation and flocculation removes impurities precisely colloidalimpurities through the phenomenon of destabilization, bridging and sweep coagulation. In order tohave an effective treatment factors governing coagulation are to be optimized to determine the dose,pH, mixing time etc. The prime objective of the present study is to characterize the sugar industryeffluents, test the efficiency of both chemical and natural coagulants to treat these effluents and bringout a comparison and potential of natural coagulants with that of chemical coagulants. Jar testapparatus was employed all coagulation studies and the results were promising with reduction inparameters like colour (99.28%), electrical conductivity (60.39%), turbidity (97.67%), chloride(69.23%) and total dissolved solids (60.42%) highest by ferric chloride followed by the naturalcoagulants. The findings of the study suggest that the lowest dose of 0.25g/l was optimum to removethe physico-chemical parameters both by chemical and natural coagulants and since natural coagulantswere equally competent with chemical coagulants these can be substituted towards achieving greentreatment options.
