Treatment of a Food Industry Dye, Brilliant Blue, at Low Concentration Using a New Photocatalytic Configuration

et al. 2023

Food coloring has become one of the main sources of water pollution. Brilliant blue (BB) is one of the dyes used in the food industry. Heterogeneous photocatalysis is increasingly used to decontaminate polluted water from food industries. The objective of this paper was to treat this pollution using a photoreactor at the laboratory (batch) and pilot scales. The photodegradation of the brilliant blue dye, chosen as a model of pollutant, was performed at room temperature in an aqueous solution of titanium dioxide supported on cellulosic paper in the presence of an external UV lamp. The surface morphology of this photoactive tissue was characterized by SEM and FTIR. The performances of two geometric configurations were examined (batch reactor and annular recirculation reactor) in accordance with degradation and pollutant mineralization. The performance of the photocatalytic system was optimized by a parametric study to improve the impact of the different parameters on the efficiency of the degradation process, namely the initial concentration of the pollutant, the TiO2 cycle, the pH of the solution with the recirculating reactor, and the flow rate. The results showed 98% degradation of brilliant blue at the laboratory scale and 93.3% and 75% at the pilot flow rates of 800 and 200 L·h−1, respectively. The supported semiconductor showed good photodegradation ability during BB decomposition, showing that photocatalysis is a promising technique for water purification.

“…The eye nerves of humans and animals is disturbed when they are in contact with MB for a long time and the MB enter into aquatic plants to interfere with the original balance system between ions, resulting in normal the absorption, transportation, regulation and penetration of ions are hindered, which causes metabolic disorders and severely damages the ecosystem [5] . Therefore, the remove of MB from wastewater has attracted more and more attention, and the remove method mainly including that adsorption, [6] membrane separation, [7] coagulation‐flocculation, [8] air flotation, advanced oxidation, [9] Fenton oxidation, [10] light catalysis, [11] anaerobic biodegradation and aerobic biodegradation [12] . Due to low cost and convenient operation, the adsorption method is the most suitable and reasonable choice for removing organic pollutants and inorganic heavy metal ions from wastewater [13]…”

A series of hydrogels were successfully prepared with low grade palygorskite and hydroxypropyl methyl cellulose as raw materials by free radical graft copolymerization method. The morphology, functional groups, crystalline phases and thermal stability of the hydrogels were characterized by SEM, FT‐IR, XRD and TG, respectively. The adsorption properties of hydrogels were tested. The water absorption rate of hydrogel with Jiangsu Xu Yu palygorskite (PGSH), Gansu Linze white grey palygorskite (WPGSH) and Gansu Linze red palygorskite (RPGSH) as raw materials was 1332 g/g, 1204 g/g and 1146 g/g, respectively. The three hydrogels showed excellent adsorption capacity for 100 mg/L methylene blue solution at room temperature, and the maximum adsorption capacities of PGSH, WPGSH and RPGSH were 236.44 mg/g, 227.72 mg/g and 223.01 mg/g, respectively. The adsorption kinetics of methylene blue over hydrogels was a pseudo two stage kinetic equation.

Simultaneous hydrogen production and decolorization of denim textile wastewater: kinetics of decolorizing of indigo dye by bacterial and fungal strains

et al. 2020

This study proposes the treatment and valorization of denim textile effluents through a fermentative hydrogen production process. Also, the study presents the decolorizing capabilities of bacterial and fungal isolates obtained from the fermented textile effluents. The maximum hydrogen production rate was 0.23 L H 2 /L-d, achieving at the same time color removal. A total of thirtyfive bacteria and one fungal isolate were obtained from the fermented effluents and screened for their abilities to decolorize indigo dye, used as a model molecule. From them, isolates identified as Bacillus BT5, Bacillus BT9, Lactobacillus BT20, Lysinibacillus BT32, and Aspergillus H1T showed notable decolorizing capacities. Lactobacillus BT20 reached 90% of decolorization using glucose as co-substrate after 11 days of incubation producing colorless metabolites. Bacillus BT9 was able to utilize the indigo dye as the sole carbon source achieving a maximum decolorization of 60% after 9 days of incubation and producing a red-colored metabolite. In contrast, Bacillus BT5 and Lysinibacillus BT32 exhibited the lowest percentages of decolorization, barely 33% after 16 and 11 days of incubation, respectively. When Aspergillus H1T was grown in indigo dye supplemented with glucose, 96% of decolorization was reached after 2 days. This study demonstrates the valorization of denim textile effluents for the production of hydrogen via dark fermentation with concomitant color removal.
