“…Biological treatments include aerobic treatments (activated sludge, trickling filtration, oxidation, ponds, lagoons, and aerobic digestion) and anaerobic treatment (anaerobic digestion, septic tanks and lagoons) [72]. It also includes the treatment by fungal biomass, such as Aspergillus fumigates, effectively used to remove reactive dyes from textile wastewater [77]. A large number of microbes can degrade dyes, and this approach is gaining momentum [78].…”

The textile industry is one of the most chemically intensive industries, and its wastewater is comprised of harmful dyes, pigments, dissolved/suspended solids, and heavy metals. The treatment of textile wastewater has become a necessary task before discharge into the environment. The textile effluent can be treated by conventional methods, however, the limitations of these techniques are high cost, incomplete removal, and production of concentrated sludge. This review illustrates recent knowledge about the application of floating treatment wetlands (FTWs) for remediation of textile wastewater. The FTWs system is a potential alternative technology for textile wastewater treatment. FTWs efficiently removed the dyes, pigments, organic matter, nutrients, heavy metals, and other pollutants from the textile effluent. Plants and bacteria are essential components of FTWs, which contribute to the pollutant removal process through their physical effects and metabolic process. Plants species with extensive roots structure and large biomass are recommended for vegetation on floating mats. The pollutant removal efficiency can be enhanced by the right selection of plants, managing plant coverage, improving aeration, and inoculation by specific bacterial strains. The proper installation and maintenance practices can further enhance the efficiency, sustainability, and aesthetic value of the FTWs. Further research is suggested to develop guidelines for the selection of right plants and bacterial strains for the efficient remediation of textile effluent by FTWs at large scales.

Cobalt/copper-based bimetallic metal−organic frameworks (Co/Cu-MOFs) are synthesized using two organic ligands in the presented research work. Subsequent incorporation of bismuth oxyiodide (BiOI) into the MOFs via a hydrothermal approach formed composite materials (Co/Cu-MOFs@BiOI) that exhibit an efficient photocatalytic activity. The synthesized materials were thoroughly characterized by using X-ray diffraction, Fourier transform infrared, and scanning electron microscopy techniques. Co/Cu-MOF @BiOI was employed as a novel photocatalyst for the degradation of cationic methylene blue (MB) dye in aqueous solution under visible light. The combination of Co/Cu-MOFs with BiOI significantly enhanced the photocatalytic degradation efficiency of MB relative to that of bimetallic MOFs (Co/Cu-MOFs) owing to increased visible light absorption and reduced charge-carrier recombination. A Box−Behnken design (BBD) statistical study is employed in conjunction with response surface methodology (RSM) to optimize the dye degradation process. The BBD-RSM methodology successfully identified the optimal dye degradation conditions, including an initial dye concentration of 6 ppm, irradiation time of 120 min, and catalyst dosage of 0.14 g L −1 . Furthermore, the predicted coefficient of regression (R 2 ) value under these optimal conditions using BBD-RSM was 99%, indicating a strong correlation between the prediction and experimental observation. These results demonstrate the strong potential of the Co/Cu-MOF @BiOI composites as efficient photocatalysts for the removal of organic dyes.

“…Wastewater contains both organic and inorganic chemicals consisting of dangerous compounds including dyes and surfactants, and also other contaminants such as dissolved and suspended solids, salts, dispersing agents, acids, alkalis, softeners, fixing agents, and other toxic compounds [1]. These dye wastes and contaminants can remain in the environment for a very long period if adequate treatment is not administered, and subsequently, they become oncogenic and mutagenic through compositional changes [2].…”

Textile wastewater including a large number of dyes and heavy metals can have adverse impacts on human health and surface water. In this work, biosorption Toluidine Blue from aqueous media onto natural Polypourus squamosus fungi as a low-cost biosorbent was investigated. Central Composite Design (CCD) in Response Surface Methodology (RSM) was successfully applied to optimize the biosorption condition. Medium parameters affected the biosorption of Toluidine Blue were determined to be initial pH, initial Toluidine Blue (Tb) concentration, temperature, and absorbent dosage. All experiments were carried out in a batch system using 250 mL flasks containing 100 mL of Toluidine Blue solution with a temperature-controlled magnetic stirrer. The Tb concentrations remaining in filtration solutions after biosorption were analyzed using UV-Spectro. With the obtained quadratic model, the optimal conditions for maximum biosorbed Toluidine blue were calculated to be 7, 27.5 mg/L, 35°C and 0.05 g for pH, C°, T (°C) and adsorbent dosage, respectively. Furthermore, most known isotherm models such as Langmuir and Freundlich were computed to find the best-fitted model.
