Physicochemical Characteristics, Identification of Bacteria and Biodegradation of Industrial Effluent
C. M. Noorjahan
Abstract :
An investigation was carried out to analyse Physico–chemical parameters like colour, odour, pH, EC, TSS, TDS, BOD, COD, chromium and copper of untreated tannery effluent and to degrade the effluent using native bacteria. The results of the parameters analysis revealed that untreated tannery effluent was black in colour with offensive odour. pH was alkaline with high organic load such as EC, TSS, TDS, BOD and COD which were higher than the permissible Since the effluent had high organic load, microbes (bacteria) present within the effluent was identified and isolated. The results of the study revealed the occurrence of 4 species of bacteria namely Escherichia coli, Klebsiella sp., sp., Pseudomonas sp. and Staphylococcus aureus. The presence of bacteria indicates the pollutional status of the untreated tannery effluent suggesting that it should be treated before its disposal using the biological method particularly native bacteria for compå their degrading efficiency. The results of the degradation study shows that native bacteria E.coli was found to be very much successful in reduction of toxic substances at the percentage range of 54–91% and the biotreated water can be reused for the agricultural and aqua cultural purposes.
