“…Studies of these authors [27, 36] reported TDS values of textile effluents as 860 mg/L and 1260 mg/L, respectively, which are much higher than the TDS values recorded in the present study. The mean values of TDS at sampling sites U and D were within standards of [30] since water with a TDS < 1200 mg/L generally had an acceptable taste for drinking purposes.…”

The study was conducted in 2013/14 with the objective of determining the effects of Bahir Dar textile factory effluents on the head of Blue Nile River water quality. Dissolve oxygen was higher at the upstream site of the river, whereas BOD5, TDS, and total alkalinity values were higher at wastewater outlet of the factory site. The mean values of dissolved oxygen, BOD5, and total alkalinity were above maximum permissible limits set by WHO for drinking water at head of Blue Nile River. The mean value of BOD5 was above permissible limit of IFC for textile effluents to be discharged to surface water. A total of 836 aquatic macroinvertebrate individuals belonging to 21 families were collected. The Shannon-Wiener Diversity Index, the Hilsenhoff family-level biotic index, family richness, and percent dipterans were calculated. Hilsenhoff family-level biotic index and percent dipterans metrics differed significantly among sampling sites (P < 0.05). Hilsenhoff family-level biotic index was higher at the most downstream site but percent dipterans were higher at site of discharge of effluent to the head of Blue Nile River. Therefore, there is indication that effluent demands frequent control and proper treatment before being discharged to the environment.

“…A substantial amount of these colorants is released into water during the dyeing and washing processes, which is of serious concern due to their potential role in mutagenesis and carcinogenesis . Apart from this, these dyes disturb aquatic ecosystems by reducing the rate of photosynthesis . Application of dye‐containing textile wastewater to the soil may alter soil biological properties including the microbial community composition and activities of soil enzymes .…”

Azo dyes can be degraded by azoreductases that achieve initial decolorization of the dye molecule through cleavage of the azo bond. Here we characterized membrane-bound azoreductase enzyme expressed by Shewanella sp. strain IFN4, which is a particularly efficient azo dye degrading bacterium. Initial studies showed that this bacterium was capable of decolorizing a wide variety of azo dyes including Reactive Black 5, Acid Red 88, Direct Red 81, Acid Yellow 19, and Disperse Orange 3. These structurally different azo dyes were also found to be reduced by the membrane-bound azoreductase showing the wider substrate specificity of the enzyme. Maximum enzyme activity was observed at pH 8 and 45°C with Reactive Black 5 as a substrate, and was stimulated on the addition of flavin or quinone compounds. The azoreductase was partially purified using a combination of ammonium sulfate precipitation followed by anion exchange chromatography. The cell membrane azoreductase was identified by non-denaturing gel electrophoresis and was shown to have a molar mass of 33 AE 0.5 kDa. Analysis of protein fragments by mass spectrometry showed high similarity with a Na(þ)translocating NADH-quinone reductase, previously identified in different species of the genus Shewanella. This enzyme is the first to be identified as a primary functional membrane-bound azoreductase used by members of the genus Shewanella to degrade azo dyes.Abbreviations: AQDS, anthraquinone-2,6-disulfonic acid; AQS, anthraquinone-2-sulfonic acid; AR 88, acid red 88; AY 19, acid yellow 19; CID, collision-induced dissociation; DO 3, disperse orange 3; DR 81, direct red 81; DTT, dithiothreitol; EDTA, ethylenediaminetetraacetic acid; MudPIT, multidimensional protein identification technology; Nano-LC/MS, nano liquid chromatography-mass spectrometery; NADH, nicotinamide adenine dinucleotide (reduced); RB 4, reactive blue 4; RB 5, reactive black 5; SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis. 1523

“…COD reduced 69% from the textile effluent with the combined treatment of Nostoc, Eichhornia crassipes and Pistia stratiotes. With combined treatment of only Nostoc and Eichhornia crassipes, COD reduced 65% in glass containers (Roy, 2008;Roy et al, 2010). pH reduction from 11.2 to 8.6, showed the algae can reduce textile wastewater metallic contaminants (Shrivastava and Praksh, 1991).…”

Textile wastewater contains large quantities of organic and inorganic compounds, which cause toxic and hazardous pollutants in the environment. Efficacy, efficiency and feasibility of the biological treatment method using macrophytes and algae were investigated, and various physicochemical parameters (TSS, TDS, pH, color, EC, DO, BOD, COD and metal concentration) were also analyzed. In pre-treated sample, TSS, TDS, pH, temperature, DO, BOD, COD, EC and color were recorded as 913 mg/L, 2250 mg/L, 9.4, 41°C, 2.84 mg/L, 358 mg/L, 721 mg/L, 1555 μS/cm and 1347 TCU respectively. As, Cr, Pb and Cu (heavy metals) were observed exceeding the limit stipulated by WHO. COD and the pH reduction was effective in biological treatment with aquatic plants, algae and their combination, but not significant for color removal. Eichhornia treatment found most effective in reducing BOD, COD, TDS and TSS. Mixed treatment reduced the pH from 9.4 to 7.5. Both macrophytes and algae exhibited appreciable heavy metal uptake tendency, but Eichhornia crassipes was identified as the most effective in heavy metal removal because of its extensive root system. An Eichhornia based adsorbent was prepared for removal of color from the wastewater and found to be capable of removing 58% of the color. The investigation erected pathway towards phytoremediation of polluted surface water in lakes and rivers, too.
