Abstract

Water is the most important in shaping the land and regulating the climate. It is one of the most important compounds that profoundly influence life. The quality of water usually described according to its physical, chemical and biological characteristics. Due to rapid industrialisation, daily industries are discharging polluted water causing heavy and varied pollution in aquatic environment leading to depletion of aquatic biota. Due to this contaminated water human suffers from water borne diseases. It is therefore necessary to check the water quality by physic-chemical parameters like pH, conductivity, alkalinity, acidity, DO, BOD, COD, sulphate, chloride, nitrite-nitrates etc. The present work has been carried out to know the physico-chemical contents in the industrial effluent from Hebbal area. The concentration of calcium and magnesium is 94.18 ppm and 94.12 ppm respectively. The values are greater than WHO rating i.e., 2.5 ppm. Hence it causes hardness of water. Sulfate is lower 33.62 ppm compared to WHO rating 62.5 ppm. It doesn’t cause dehydration. The concentration of nitrite was found to be 0.09 ppm lower than WHO rating 12.5 ppm, indicating not harmful to the environment. Concentration of chloride content in the given water sample was found to be 162.94mg/100ml. In the industrial effluent, the concentration of chloride is 162.94 ppm greater than WHO ranging 62.95 ppm. High level of chloride can have negative impact on an ecosystem. Hence the above industrial effluent cannot be released into any water bodies without treatment.
