QGIS evaluation and treatment of liquid wastes collected from industries of West Tamil Nadu

Distillery effluents damage aquatic plants and species, causing eutrophication of water bodies, soil solidification, salinity, water logging and anaerobiosis. Water quality indices of the wastewater samples collected from sugar, oil and eucalyptus distilleries were analyzed as per standard methods. The recorded values pertaining to certain parameters exceeded the prescribed levels and were mapped and interpolated using Inverse Distance Weighting and Graphical Modeling using Quantum Geographical Information System software 3.16. Native tamarind hull (NTH) and native corn husk (NCH) were utilized to minimize the exceeding values of the tested parameters. Native tamarind hull (NTH) was subjected to chemical modification, which (modified tamarind hull - MTH) exhibited efficient reduction of higher concentrations of the tested parameters and showed a noticeable difference in the removal ability as compared to the native materials. The results revealed MTH as a promising solution for the treatment of distillery wastewaters.
