PHYSICO-CHEMICAL CHARACTERISTICS OF SUGAR MILL EFFLUENTS-CURRENT SCENARIO IN BHADRAVATHI TALUK, KARNATAKA, INDIA

Abstract

The physico-chemical profile of effluent from sugar mill was determined during 2003-04. The parameters measured are temperature (30°C) colour, turbidity (84.7 NTU) pH (8.1), electrical conductivity (5530μmhos/cm), BOD (6856 mg/L), COD (7432 mg/L), total dissolved solids (2516 mg/L), chloride (1894 mg/L) total alkalinity (254 mg/L), total hardness (342 mg/L), sulphate (540 mg/L), phosphate (224 mg/L), total acidity (45 mg/L), calcium (364 mg/L) and magnesium (151 mg/L). According to the permissible level suggested by Bureau of Indian Standards almost all the water quality parameters in the sugar effluents have been found to be very high and well above the permissible limits. It is concluded that the wastewater discharged from the sugar industry is highly polluted, as it exceeded the prescribed limits for irrigation and public use.
