The conventional rinsing after bleaching to remove the residual hydrogen peroxide, harmful to the dyes either in solution or on the fabric, was replaced by enzymatic cleaning using catalases. The catalasetreated bleaching liquor was reused for dyeing. Though no hydrogen peroxide was detected after the enzymatic process, the bleaching bath composition caused unacceptable colour changes on dyed f...

Abstract In recent days, the waste productions from industries are increased and direct discharge of wastes causes various pollution to environment. Wastewater treatment in textile dye industry mainly involves highly colored wastewater containing variety dyes different concentrations. The dyeing using types pigments concentration during their several production steps. These a which contains org...

A wide range of chemicals and dyes are being used in textile industry, and are often found in the wastewater produced. This study attempts to investigate the reduction of COD, TSS, and dye in effluents from the dyeing and washing unit of textile industry, using electrocoagulation process. The reactor is equipped with 10 iron electrodes, connected to a direct current (DC) source in a monopolar e...

The residual dyes from different sources (e.g., textile industries, paper and pulp industries, dye and dye intermediates industries, pharmaceutical industries, tannery, and Kraft bleaching industries, etc.) are considered a wide variety of organic pollutants introduced into the natural water resources or wastewater treatment systems. One of the main sources with severe pollution problems worldw...

Textile industry is one of the most important and rapidly developing industrial sectors. It has a high importance in terms of its environmental impact, as it consumed high amount of processed water and produce highly polluted discharge water in large amount. Dying and printing mills comprises various operations include desizing, scouring, washing, finishing etc so they produces large amount of ...
