“…The ability of P. aeruginosa to reduce COD level have been reported in several studies. In one study, the potential use of P. aeruginosa in textile wastewater degradation have been explored (Selvakumar et al, 2010). The study showed that 90% COD removal was achieved with combination of bio-treatment and electrooxidation process under aerobic and anoxic conditions.…”

“…Pseudomonas aeruginosa is unable to grow in the absence of glucose and thus affects the decolorization activity (Selvakumar et al, 2010). Many studies supported this factor where very few microorganisms are capable of using dye as their sole carbon source because of the complex structure of these compounds.…”

Azo dyes are widely used in the textile industry. The release of these undesirable dye effluents to the environment can be toxic and carcinogenic towards humans and other organisms. The removal of these dyestuff wastes using the biodegradation method is to consider eco-friendlier compared to physical and chemical methods. Thus, this study was conducted to identify and analyze the biodegradation activity of the azo dye by the potential bacteria isolated from textile dye effluent. For decolorization analysis, the isolated bacteria were inoculated into flasks containing mineral salt medium added with Reactive Green 19 dye (50 mg/L) and was incubated for 9 days at 37°C. Spectrophotometry analysis was carried out at 635 nm to analyze the level of azo dye degradation. From the analysis, we found that the optimum pH, temperature, and dye concentration for the decolorization were detected at pH 7, 37°C, and 50 mg/L, respectively. The identified bacteria Pseudomonas aeruginosa showed 94% decolorization of Reactive Green 19 dye after 9 days of incubation. The result of decolorization activity by this bacterial strain can be used in the biological treatment of textile effluent.

“…Dyes have high chemical and biological stability which requires effective remediation methods. Removal techniques of dye molecules from waste water include physical (Eren 2009;Silva et al 2012), chemical (Nawi and Sabar 2012;Saravanan et al 2013) and biological processes (López et al 2006;Selvakumar et al 2010). Among these methods, adsorption using porous materials and heterogeneous photocatalysis (Gnanasekaran et al 2015) had been demonstrated as promising techniques.…”

An immobilized clay composite (BEN-PVAG) on a glass plate (GP) was fabricated using bentonite powder (BEN) and glutaraldehyde cross-linked polyvinyl alcohol (PVAG) as the adsorbent and adhesive, respectively. The immobilized bentonite composite (BEN-PVAG) was characterized using SEM, EDX, FTIR, and BET analysis. The adsorption capacity of BEN-PVAG was examined using methylene blue (MB) as the model pollutant. The results indicated that the adsorption of MB onto BEN-PVAG obeyed pseudo-second-order kinetics. In addition, the adsorption of MB by the immobilized BEN-PVAG was controlled by intra-particle diffusion. In contrast, the adsorption of MB by the suspended BEN-PVAG composite was dominated by film diffusion. The immobilized BEN-PVAG was then applied as the adsorbent sublayer for the fabrication of P-25TiO 2 /BEN-PVAG/GP bilayer system where P-25TiO 2 was deposited as the top layer. The fabricated bilayer system exhibited synergistic photocatalytic-adsorptive removal of MB upon irradiation with a light source, while experiment in the dark yielded only adsorption process. The rate of the synergistic photocatalytic-adsorptive removal of MB by the P-25TiO 2 / BEN-PVAG/GP was 5.3 times faster than the suspended P-25TiO 2 . The result implied the positive impact of the BEN-PVAG adsorbent sub-layer on the immobilized P-25TiO 2 photocatalyst. Most important, the immobilized P-25TiO 2 /BEN-PVAG/GP provided a convenient reuse of the catalyst over time where the treated water could be directly discharged without the need of filtration.
