Textile Dye Wastewater Biotreatment—A Project Empowering Female Leadership through International Exchange
Publication: World Environmental and Water Resources Congress 2018: International Perspectives, History and Heritage, Emerging Technologies, and Student Papers
ABSTRACT
International exchanges and sponsorships allow female scholars opportunities for broader engagement in the scientific community. In 2016, Noshaba Hassan Malik, a Ph.D. student at Quaid-i-Azam University in Islamabad, Pakistan, conducted research with Dr. Heidi L. Gough, faculty at the University of Washington. The exchange allowed both scholars to expand their knowledge base and to better understand differences between the two academic institutions. Particularly, because women tend to be less engaged in international scientific exchanges, this model serves as an example of the power of long-term exchange in improving female engagement in global water research. During the exchange, Dr. Gough and Ms. Malik worked together to characterize the biotreatment potential of newly isolated bacteria that were capable of degrading dyes found in textile wastewater. The approach of using of bacteria capable of decoloring dyes has been proposed for development of biologic treatment options for wastewater produced during textile dyeing. Specialized bacteria have been reported that decolor textile wastes. However, knowledge of the kinetics of decolorization is needed to develop and model a treatment approach. This study documented the ability of newly-isolated bacteria to degrade a mixture of three dyes (reactive red, blue, and yellow) in batch reactors, and established their kinetic rates of degradation; this data is presented in the main text. An over-arching goal of the project is to apply kinetics knowledge for development of larger-scale reactor systems that can be used in developing nations where currently available treatment is often not an economically viable option.
