Description 770-782
This study focuses on the quantitative and qualitative characterization of coloured wastewater of an institutional dyeing
laboratory and its treatment via coagulation/flocculation (CF), where the cumulative volume of wastewater is large and
generally discharged without any treatment. Primarily woven fabric pieces of cotton, wool, silk, nylon, acrylic, and polyester
are dyed using standard dyeing procedure maintaining the liquor ratio of 50. Total 23 dyes from the different class of dyes
viz., direct, reactive, acid, cationic, sulfur, vat, and disperse are used for dyeing of fabric samples. The generated colored
wastewater is characterized for its volume, pH, total dissolved solids, turbidity, colour concentration, and biological and
chemical oxygen demand. The qualitative characteristics of generated coloured wastewater influenced the preparation of
two types of simulated coloured wastewaters which later subjected to CF using the coagulants (ferric chloride and a
commercial polymeric coagulant). The pH of coagulation bath, coagulant dose and type influenced the color removal
efficiency, where the polymeric coagulant performed better as compared to ferric chloride. Adaptable approaches and
strategies have also comprehended in this study, which are adaptable to reduce the colored wastewater volume, thus leading
to achieve the sustainability.
