Abstract |
|
A study was undertaken to assess the characteristics like physical and chemical analysis of the wastewater of Gulbarga city. The characteristics involves the analysis of total solids, suspended solids, dissolved solids, volatile solids, biological oxygen demand, chemical oxygen demand, phosphates, ammonical nitrogen, nitrites, nitrates. The study was carried out for 6 different sources of discharge in the Gulbarga city comprising residential, commercial and educational institutional areas. After analyzing the physico chemical characteristics suitable interpretation analysis is carried out by statistical calculation viz. mean, standard deviation, coefficient of variation, correlation coefficient, rate of reaction and regression analysis are worked out. The present study shows the waste water is organic in nature having average values of BOD of 444 mg/l, COD of 815 mg/l, total solids of 1401 mg/l, dissolved solids of 1146 mg/l and suspended solids of 255 mg/l. Since BOD/COD ratio of all the sampling points lies near the the range of generally accepted ratio of 0.6, the average ratio of 0.55 for A1 to A6 are found, hence it is concluded that sewage is organic in nature and waste can be treated biologically. |
