Sulfonic textile wastewater

For Reactive Blue 19 [2580-78-1] (Cl 61200 its reactive form, the vinyl sulfone (5), was found in the effluents of a textile mill and a wastewater treatment plant. The hydrolysis product of the vinyl sulfone was detected only in the effluent of the textile mill (257). 

Benzene and naphthalene sulfonate moieties are present in the structures of many dyes that can be found in large amounts in wastewaters from textile and food industries. Even if wastes are decolored before the final discharge, not enough attention is nowadays devoted to the identification of possible uncolored degradation products, potentially toxic, that form during the decolorization process and are discharged into the aquatic systems. Besides sulfonate derivatives, aromatic amines have also been reported as possible degradation products of dyes [109],... 

Chlorine-mediated electrolysis has also been used efficiently for the treatment of real wastewater such as landfill leachate (Chiang et al. 1995 Vlyssides et al. 2003), textile effluents (Lin and Chen 1997 Vlyssides et al. 2000 Yang et al. 2000 Iniesta et al. 2002), olive oil wastewater (Israilides et al. 1997 Panizza and Cerisola 2006c), industrial effluent containing aromatic sulfonated acids (Panizza et al. 2000), and tannery wastewaters (Vlyssides and Israilides 1997 Szpyrkowicz et al. 2001 Panizza and Cerisola 2004a). 

Nanohltration membranes allow partial permeation of monovalent salts such as sodium chloride, while they completely reject bivalent salts and hardness from aqueous solutions. This has led to the use of NF membranes as water softeners by removal of total hardness and sulfates from seawater and for removal of NaCl from cheese whey. NF membranes have also been successfully utilized for treating textile dye and olive processing wastewaters to recover recyclable water. Another common application is removal of color from effluents and process solutions. One such example is the separation of color causing compounds such as lignin sulfonates from paper pulping wastewater. 

Benzene (BS) and naphthalene sulfonates (NPS) are commonly used in the textile industry as dye bath auxiliaries and in the tannery industry as dispersants and wetting agents. After application, these compounds are discharged into surface waters and their presence in industrial effluents was not reported due to the lack of an appropriate analytical technique. Recently, ion-pair chromatography-ESI-MS and LC-ESI-MS was developed to determine BS and NPS with the final goal of determining polar, ionic, and water-soluble pollutants in wastewater [7],... 

Synthetic dyes, including azo compounds, are widely used as coloring agents in a variety of products such as textiles, paper, leather, gasoline, and foodstuffs. Synthetic dyes persist even after conventional water treatment procedures due to their hydrophilic character and high solubility (they usually bear carboxylic or sulfonic acid groups in their structure) and, therefore, can be distributed in the environment from urban and industrial wastewater.
