ABSTRACT

 

The physico-chemical parameters in wastewater of seven stations of Bahana nala and Sapua nala in Berhampur Municipal Corporation, Odisha (India) were studied during January-2009 to December-2009. The pH, dissolved oxygen, biological oxygen demand, chemical oxygen demand, total dissolved solid, total suspended solid, calcium hardness, magnesium hardness, total hardness, electric conductivity, nitrate and phosphate were studied. The pH varied from 6.8 to 8.2 the dissolved oxygen content was highest being 8.1 mg/l and lowest DO content was 2.0 mg/l. Biochemical oxygen demand varied between 1.6 mg/l to 15.6 mg/l. Chemical oxygen demand varied from 8.6 mg/l to 85 mg/l. Total suspended solids and total dissolved solids varied from 15 mg/l to 600 mg/l and 22 mg/l to 4750 mg/l respectively. Similarly, electric conductivity varied from 22.4 mg/l to 3979.5 mg/l. Total hardness varied from 33 mg/l 5850 mg/l. Calcium hardness and magnesium hardness varied from 12 mg/l to 2600 mg/l and 21 mg/l to 3550 mg/l. Nitrate value varied between 0.106 mg/l to 8.15 mg/l. The phosphate value varied between 0.001mg/l to 2.031 mg/l. The physico-chemical parameter values varied between the station and almost all parameters were lower as compared to the permissible limit prescribed by the United State Environmental Protection Agency and World Health Organization (WHO).
