Effluent Decolorization for Sustainable Textile: Wastewater Treatment, Environmental Risk and Human Health

Abstract

Merely 0.4% of the world's water is accessible for human and animal consumption, a stark reminder of our planet's limited freshwater resources. With the escalating demands driven by population growth and industrial pollution, wastewater generation rates have surged. Of particular concern is the textile industry's heavy reliance on water in production processes, coupled with the challenge of treating wastewater laden with significant concentrations of dyestuffs, underscoring the urgent need for ecologically sound solutions. In this study, we explore the efficacy of various parameters, including mechanical agitation and ozone dosage, in the decolorization using Fuzzy Logic estimation techniques. Our findings reveal that higher mechanical agitation enhances ozonation rates, albeit at the expense of decreased efficiency in degrading dyeing auxiliary chemicals.
