“…Wastewater discharged from the textile industry is characterised by high chemical demand, low biodegradability, and high salt content (Alinsafi et al 2005;Wu et al 2004;Karthik and Gopalakrishnan 2012a, b, c, d). Some of the dyes such as azo dye are carcinogenic and cause serious health problems such as cancer (Karthik and Gopalakrishnan 2013a, b;Rita Kant 2012;Joshi et al 2004).…”

In the whole world today there has been a growing awareness of the damage caused to the environment by the haphazard use of chemicals, some of which are very poisonous and carcinogenic. The textile industry has been strongly criticised as being one of the world's worst lawbreakers in terms of pollution because it demands a large amount of water and chemicals. Although air, water, and noise pollution are created at every step of fabric treatment, the most problem-filled is fabric wet processing, in terms of the huge amount of water and goodly number of chemicals used in wet processing and on completion of the process, leftover dyes and chemicals together with water are discharged as effluents. As the amount of sludge created by wastewater treatment increases, effective reuse and safe disposal of sludge becomes most important. This chapter provides comprehensive information about the various methods and techniques in recycling textile effluents and sludge treatment process of textile effluents.

“…The shift of bands belonging to Si-O and all of -OH vibrations and/or change in their intensities imply the presence of strong electrostatic interactions and also hydrogen bonds between dye molecules and these functional groups. 32 The -OH plays a significant role for the adsorption of adsorbate molecules via hydrogen bonding.…”

Abstract:The main aim of this study was to evaluate the efficacy of montmorillonite clay for the adsorption of C.I. Basic The adsorbent dosage was found to be the key factor that controlled dye adsorption. The adsorption kinetic and isotherm were also investigated. The rate of adsorption showed the best fit with the pseudo-second order model (R 2 = 1). The results of the isotherm study fit the Freundlich model (R 2 > 0.9). The physicochemical properties of the sample were determined by XRF, XRD, FT-IR, and N 2 adsorption-desorption.
