Abstract:
The present experiment is focused to know the physico-chemical characteristics of sewage at different concentrations following its dilution with drinking tap water under the laboratory conditions. Selected physico-chemical parameters viz. pH, turbidity, total dissolved solids, dissolved oxygen, bio-chemical oxygen demand and chlorides were analyzed during this study. Biochemical oxygen demand showed maximum fluctuation while the pH showed minimum fluctuation among all the parameters. The related difference pH was 10.29% lower, Turbidity was 14150 % higher, Total dissolved solids was 4366.66 % higher, Dissolved Oxygen was 406.25 % lower, Bio-chemical oxygen demand was 3513% higher while the chlorides were 73.25 % higher in sewage in comparison of drinking water.

Keywords: pH, turbidity, TDS, DO, BOD and chlorides, sewage
