Abstract:

The effect of treated textile dye effluent on morphology and growth pattern of Sorghum bicolor (L.) Conrad Moench. in different concentrations (0, 20, 40, 60, 80, 100%) has been studied. For this  research work  the samples from Kaveri  river near Bhavani area were taken and analysed for BOD, COD, EC, pH and concentration of reactive red (R-red)    and   reactive   black (R-black) textile dyes. The BOD at 27°C, for 3 days was observed to be 92 mg/l. The COD level was very high (2325 ppm), and the EC was  13 mS/cm at 25°C  R-red dye concentration was 242 ppm and  absorbance was 0.791. R-black dye concentration was 301 ppm. pH ranged from 4-7.  Chemical analysis was found to be far away from EPA standard of potable water. The high values of the parameters    BOD, COD, pH and EC demands pretreatment of the effluent before its discharge into water bodies. Also, the high conductivity observed shows that sufficient ions are present in the effluents, thus suggesting that the treatment may be required. The treated effluent concentration of up to 40% was supporting the germination and growth of sorghum plants with improved biomass to a considerable extent.
