Abstract:

- Environmental science and management is often the most discussed subject nowadays all over the world. In a number of countries, presently plenty of harms are associated with the effluent by industrial due to growing industrialization; this issue should be considered at large scale. Textile sector is one of the leading areas, which uses a high amount of chemicals and creating environmental pollution. Textile wet processing sector uses a lot of chemicals, surfactants and synthetic dyes, hence produce a large amount of wastewater having a high concentration of chemicals. This research is an effort to investigate the amount of residue remained in liquor after bleaching and reuses this liquor by adding a few chemicals according to the requirement. Afterward, the comparison was made between the bleached sample with fresh liquor and bleached sample with reused liquor. It was observed that bleaching with reused liquor shows good results though these results are insignificantly less than fresh bleaching liquor. On the other hand, fortunately, the color yield of dyed fabric bleached with reused liquor is higher than fresh liquor.
