“…Crude textile effluent is a complex mixture of inorganic, organic, polymeric and elemental products, as well as bases, acids, salts, detergents, mordants and fasteners; and predominantly a variety of colouring agents and dyes. The toxicity of textile effluent and dyes poses a major threat to the developing countries, who are not capable of effectively remediating such toxicants economically, and thus, these xenobiotics contaminate their valuable water resources (Khandare et al ).…”

This pilot study evaluated the effects of bacterial augmentation on the efficiency of floating treatment wetlands (FTWs) to remediate textile wastewater. Two wetland plants, Phragmites australis and Typha domingensis, were used to develop FTWs, which were then augmented with a bacterial consortium of three strains (Acinetobacter junii, Pseudomonas indoloxydans, and Rhodococcus sp.). Results showed that both plant species removed colour, organic matter, toxicity, and heavy metals from textile wastewater and their removal efficiency was further enhanced by augmentation with bacteria. The maximum removal efficiencies of colour, COD and BOD after an 8‐day period were 97, 87 and 92%, respectively, by FTWs carrying P. australis inoculated with the bacterial consortium. Furthermore, the same combination showed 87–99% reduction of heavy metals in the textile wastewater as well. These results indicate that FTWs can be used for the treatment of textile effluent and their working efficiency can be improved by plant‐bacterial synergism.

“…The peak at 3410 cm À1 could be assigned C-H stretching. The peaks at 1610, 1430, and 1150 cm À1 could be attributed to C¼O, O-H, and S¼O, respectively (Khandare et al, 2013). These results showed that the real ink wastewater would have the various functional groups and ions in its components.…”

“…The real ink wastewater had the several peaks located in 3550, 3410, 1610, 1560, 1430, and 1150 cm À1 . The peaks at 3550 and 1560 cm À1 could be related to N-H bonds (Khandare et al, 2013). The peak at 3410 cm À1 could be assigned C-H stretching.…”

Bamboo chars and bamboo activated carbons prepared by steam activation were applied for ink wastewater treatment. Bamboo char at 800 °C was the best for the removal of color and chemical oxygen demand (COD) from ink wastewater compared to bamboo chars at 300 to 700 °C due to higher surface area and mesopore volume. Bamboo activated carbon at 600 °C (S600) was the best compared to bamboo activated carbon at 800 °C (S800), although S800 had larger surface area (1108 m(2)/g) than S600 (734 m(2)/g). S600 had higher mesopore volume (0.20 cm(3)/g) than S800 (0.16 cm(3)/g) and therefore achieved higher color and COD removal. All bamboo activated carbons showed higher color and COD removal efficiency than commercial activated carbon. In addition, S600 had the superior adsorption capacity for methylene blue (0.89 mmol/g). Therefore, bamboo is a suitable material to prepare adsorbents for removal of organic pollutants.

“…The spectrum of the control dye showed a peak at 3445 cm -1 for free OH (O-H stretching vibration), 1632 cm -1 for the azo bond N=N stretching vibration, 1227 cm -1 for the S=O stretching vibration, 1030 cm -1 for the C-N stretching vibration, and 719 cm -1 for the C-C bond of a mono-substituted benzene ring with adjacent free H atoms. The differential spectrum of extracted metabolites obtained in the individual SBR effluents shows a peak at 3030 cm -1 for N-H stretching, with the appearance of peaks at 2920.40 and 2847.80 cm -1 indicating C-H stretching, and a peak at 1449 cm -1 related to O-H deformation [28]. Peaks at 1117 and 1027 cm -1 are representative of S-O stretching.…”
