The wastewater sample was poisonous after reactive printing, because it has to be diluted 20 times to achieve poison-free water, as shown by the toxicity tests with D. magna. The findings of the study conclude that the ultrafiltration step was not sufficient for treatment of such textile wastewater.

Membrane filtration of wastewater after textile printing with reactive dyes is described. The wastewater from a Slovenian factory, whose output is approx. 80% reactive dyes printed and dyed on cotton, was studied. In particular, the presence of urea, sodium alginate, oxidation agent and reactive dyes, used for the printing paste preparation, in

Reactive dyeing wastewater samples were taken from a cotton textile dyeing plant in Denizli, Turkey. The dyeing process consists of four steps, namely dyeing (1), hot rinsing (2), soap washing (3) and warm rinsing (4) as shown in Table 1.In the dyeing step, water, dyes, salt, caustic, soda and other auxiliary chemicals are added to the tank.

treatment and reuse of reactive dyeing effluents

Treatment and reuse of reactive dyeing effluents

The wastewater produced by a reactive dyeing contains: Hydrolyzed reactive dyes not fixed on the substrate, representing 20–30% of the reactive dyes applied (on average 2 g L −1 ). This residual amount is responsible for the coloration of the effluents and cannot be recycled.

Removal of dyes using agricultural waste as low-cost

Color removal from wastewater has been a matter of concern, both in the aesthetic sense and health point of view. Color removal from textile effluents on a continuous industrial scale has been given much attention in the last few years, not only because of its potential toxicity, but also mainly due to its visibility problem. There have been various promising techniques for the removal of dyes

Reactive dyes are non-degradable and toxic to environments and human being, and their solutions have some color even after wastewater treatment. To remove toxic dyes, adsorption is common choice. In this study, to improve the adsorption capacity, the effect of cationic surfactant was studied to remove reactive black 5 (RB5) by activated carbon
