EVALUATION OF INDUSTRIAL AND CITY EFFLUENT QUALITY USING PHYSICOCHEMICAL AND BIOLOGICAL PARAMETERS

Industrialization comes with its effects on life if left with untreated discharge leading to water, soil and sediment pollution. Current study aimed to evaluate industrial effluent discharge using physicochemical and biological parameters. Effluent discharge samples were taken from sugar mills, ghee mills, PVC pipe city waste, Indus river and Hand pump located at back of River Indus. PH ranged from 6.28-8.17, EC 153-615|is/cm, TDS 77-412.05mg/L TSS 2-393.6mg/L, Dissolved O2 4.29-719 mg/L and Turbidity 0-630 NTU. Titrimetric analysis (chemical) reported Ca/Mg 1-6.84mg/L HCO3- 420-1300mg/L, Cl- 24-500mg/L and no CO3- were reported Spectrophometric analysis represented both U.V and Visible light active compounds. Heavy metal reported for Fe 043-2.23, Zn 0.008-4.566, CU 0.045-1.45, Pb0.005-1.89 and Ni 001-0.522(10-6). Biological assessment showed presence of microves including Staphylococcus aurous, Pseudomonas areginosa, and enterobacter and antamoeba histolytica. As all samples were found to have increasing trends towards pollution limits therefore Industrial effluents need a continuous monitoring and proper management before discharge in order to reduce future hazards in reference to aquatic and human life .
