Parametric optimization of biological process for the treatment of textile wastewater

The textile industry accounts for two thirds of the dye market and is the largest consumer of dye in the world. During production and use in packaging, about 10% of the dye is directly lost in contaminated water causing significant damage to the environment. [3]. Bioremediation based techniques has been proved to be the most an effective and inexpensive way to reduce contamination of textile dyes. In Bioremediation microorganisms are used to decolorize and metabolize dyes used by textile dyes. In this work, bacterial strains were isolated and screened for their ability to produce enzymes and eventually to decolorize two widely used textile dye-Reactive Black 5. The dye degradation products analyzed by U-VIS techniques and biochemical tests were performed on the sample. Different bacterial cultures were analyzed for different dyes, parameters such as contaminant conc., and inoculum conc. were studied to find the % removal of dyes.
