“…10,11 Although the use of these dyes is exciting, however, their over-exposure may cause serious health problems such as hyperactivity in children, chromosomal aberrations, and allergic reactions. 12,13 Therefore, the removal of these dyes from the contaminated waters has been a hotspot-target in recent years. 14 To date, various chemical, physical, and biological treatment methods have been used for the removal of organic dyes.…”

“…As time increases, a less adsorption rate might be observed and explained due to the lack of available sites; they become unavailable when the adsorption process attains equilibrium [74,76]. Based on the zero-charge point study, the great adsorption e ciency of MB dye was favored by interaction between cationic dye molecules and anionic functional groups on the adsorbent's surface.…”

Activated carbon (AC) produced from agro-industrial waste is an interesting adsorbent in water purification and effluent treatment processes. In this work, activated biochar (BFAC) from banana peel waste (BPF) was prepared by chemical activation (NaOH) followed by pyrolysis at 600 °C to remove methylene blue (MB) from wastewater. BFAC was characterized by TGA, XRD, SEM, and FTIR techniques. The influence of dye concentration (10, 25, 50, 100, 250, and 500 mg L−1) and zero point charge (ZPC) were investigated. Besides, a Life Cycle Assessment (LCA) was conducted to evaluate and analyze the environmental effects of the developed process. BFAC presented a well-developed pore structure with a predominance of mesopores and macropores, influencing the MB removal capacity. The highest efficiency for dye removal was 62 % after 10 min to an initial concentration of 50 mg.L-1. Temkin, Langmuir, and Freundlich, isotherm models defined the adsorption isotherms well. The Langmuir model represented the best fit of experimental data for BFAC with a maximum adsorption capacity of 417 mg g−1. Regarding LCA, a prospective approach at the early stage of development was conducted to orient the transition from laboratory to industrial scale, aiming at providing a competitive CO2-based technological route. The proposed scenarios suggest that this route is promising either from the life cycle assessment or the circular economy perspective. Thus, BFAC can be considered as an adsorbent of great practical application for post-treatment of wastewater effluents aiming to remove contaminants.

“…Physical and chemical treatment methods followed by biological technology are the most widely used in the textile wastewater, such as chemical setting, adsorption, membrane filtration. Generally, the dye can not be effectively destroyed by conventional treatment methods, which may generate harmful or toxic substances 2 . Advanced oxidation processes have been studied extensively in chemically degrading various organic contaminants, such as electrochemical oxidation, photocatalytic oxidation 3 , 4 .…”

Two low-pressure ultraviolet (UV) lamps at 185/254 nm with sodium persulfate in a pilot UV device were utilized for the degradation of reactive red (B-3BF) dye wastewater compared with two UV lamps at 185/185 nm and two UV lamps at 254/254 nm. The degradation performances of UV irradiation (254/185 nm) with sodium persulfate under different degradation times, flow rates, initial pH, initial Na2S2O8 concentrations and initial dye concentrations were investigated. The experimental results illustrated that the degradation percentage of B-3BF dye could reduce to 90.42% with the energy consumption of 85.1 kWh/kg and the residual dye concentration of 1.92 mg/L by UV irradiation (254/185 nm) with initial Na2S2O8 concentration of 1.5 mmol/L and initial dye concentration of 20 mg/L. In addition, degradation performance of B-3BF dye wastewater by UV irradiation (254/185 nm) with sodium persulfate was more effective than those of UV irradiation (254/254 nm) and UV irradiation (185/185 nm). Therefore UV irradiation (254/185 nm) with sodium persulfate was promising for the degradation of B-3BF dye wastewater.
