“…Although the subsequent ozonation enabled significant reduction of RR and textile effluent toxicity towards both organisms, the results changed disproportionately according to the ozone dose [ 230 ]. Goswami et al [ 234 ] coupled a packed bed bioreactor (PBBR) filled with Arjuna ( Terminalia Arjuna ) seeds biochar immobilized with Providencia stuartii with ozonation for the degradation of Congo Red (CR) dye. Although the biological step was aerobic, it led to 92% color removal.…”

In the last 3 years alone, over 10,000 publications have appeared on the topic of dye removal, including over 300 reviews. Thus, the topic is very relevant, although there are few articles on the practical applications on an industrial scale of the results obtained in research laboratories. Therefore, in this review, we focus on advanced oxidation methods integrated with biological methods, widely recognized as highly efficient treatments for recalcitrant wastewater, that have the best chance of industrial application. It is extremely important to know all the phenomena and mechanisms that occur during the process of removing dyestuffs and the products of their degradation from wastewater to prevent their penetration into drinking water sources. Therefore, particular attention is paid to understanding the mechanisms of both chemical and biological degradation of dyes, and the kinetics of these processes, which are important from a design point of view, as well as the performance and implementation of these operations on a larger scale.

“…3(b). The biochar isolated from Providencia stuartii for congo red dye removal was reported to cost around 0.92$/kg of the biochar used [65]. The cost of wood based biochar was estimated around 0.5$/kg which was around one-sixth the cost of commercial grade activated carbon [66].…”

As(III) presence in low concentration (1-5 mg/L) in water presents a challenging problem in its removal. In the present study, biochar prepared by pyrolysis of mustard cake and loaded with Fe-Mn binary oxides through hydrothermal technique was used for adsorptive removal of As(III) from water in batch and continuous mode. The synthesised biochar exhibited mesoporous structures in the range of 2-50 nm (based on BET analysis). The maximum adsorption capacity (95.7 mg/g) obtained using biochar loaded with both Fe-Mn oxides was found to be 1.4 times higher than that of pristine biochar. The adsorption equilibria was best described by Freundlich isotherm (based on R 2 and χ 2) suggesting that the As(III) adsorption was multilayered. The external mass transfer coefficients (β L = 10-5 cm 2 /s) were observed to be higher than film (D f = 10-7-10-9 cm 2 /s) and intraparticle (D i = 10-9 cm 2 /s) diffusivities in batch mode. In column studies, Thomas model gave the best correlation coefficient (R 2 > 0.95) and the adsorption was limited by external mass transfer. Kinetic rate constant decreased with increase in initial As(III) concentration and flow rate. The oxide loaded biochar exhibited reusability up to three times for As(III) removal.

“…After model fitting, the authors reported that the adsorption behaviour of MB was better explained by the Langmuir model (R 2 = 0.996, 0.998 and 0.998) when compared to the Freundlich isotherm model (R 2 = 0.972, 0.952 and 0.715). In another study, Khan et al [38] reported the MB removal using cow dung biochar, rice husk biochar and sludge biochar and ascertained the log q e values for the two models as 17.50, 17.97, 19.21 mg/g and 1.243, 1.254, and 1.283 mg/g, respectively. Goswami et al [39] studied the adsorption of Congo red dye using Arjuna seed biochar and reported >90.0% removal in a hybrid treatment system containing biochar, microorganisms and ozone treatment.…”

Biochar prepared from Sterculia alata fruit shell showed a better performance for dye removal than the biomass from Sterculia alata fruit shell. The important process parameters—namely the pH, the amount of biochar, the initial dye concentration and the contact time—were optimized in order to maximize dye removal using biochar of Sterculia alata fruit shell as the bio-sorbent. The results from this study showed that the maximum adsorption of dye on the biochar was obtained at a biochar dosage of 40 g/L, at a contact time of 5 h, and an initial dye concentration of 500 mg/L (pH 2.0; temperature 30 ± 5 °C). The increase in the rate adsorption with temperature and the scanning electron microscopic (SEM) images indicated the possibility of multilayer type adsorption which was confirmed by better fit of the Freundlich adsorption isotherm with the experimental data as compared to the Langmuir isotherm. The values n and R2 in the Freundlich isotherm were found to be 4.55 and 0.97, respectively. The maximum adsorption capacity was found to be 11.36 mg/g. The value of n > 1 indicated physical nature of the adsorption process. The first and second order kinetics were tested, and it was observed that the adsorption process followed the first-order kinetics (R2 = 0.911).
