“…The above results clearly show that the service and saturation time were longer for the lowest volumetric flux tested and shorter for the highest volumetric flux of the influent AR27 solution assayed. Similar results were found previously for the biosorption of yellow dye tartrazine onto Moringa oleifera seeds 45 , remazol reactive dyes onto Rhizopus arrhizus NCIM 997 46 , acid blue 25 onto NaOH-treated fallen Ficus racemosa leaves 47 , and reactive blue BF-5G onto malt bagasse 48 in packed-bed columns.…”

In this work, the biosorption behavior of acid red 27 (AR27) dye using Eichhornia crassipes leaves (LECs) in a packed-bed column was investigated by varying relevant operational parameters and assessment of mathematical models. Results showed that the zero-charge point of LECs was 2.37 and that optima pH and volumetric flux of the influent solution for AR27 biosorption were 2.0 and $$56.5\ \hbox {L}/\hbox {m}^{2}\cdot \hbox {h}$$ 56.5 L / m 2 · h , respectively. The maximum specific and volumetric biosorption capacities were observed at influent AR27 concentrations and with LEC bed heights ranging between 50 and 400 mg/L and 2 and 8 cm, respectively. It was also found that if LEC bed height was increased and volumetric flux and AR27 concentration of the influent solution decreased, service and saturation time increased. Modeling results revealed that the Thomas, bed depth service time, Yoon–Nelson, dose-response, and logistic models accurately described the dynamic performance of the packed-bed column in terms of pH, AR27 concentration, and volumetric flux of influent AR27 solution, as well as that of LEC bed height. The findings revealed that LECs exhibited remarkable potential for the biosorption of AR27 from aqueous solutions in a packed-bed column and could potentially be useful for the treatment of AR27-laden wastewater.

“…In a dynamic regime, biosorption refers to the use of biosorbents in a continuous flow system, where the liquid or gas containing the pollutants is passed through an equipment that contains biological material and the pollutants are sorbed onto the biosorbent as the liquid or gas flows through the column [ 27 , 28 , 29 ]. The effectiveness of this process depends on several factors, including the type of biosorbent used, the flow rate of the liquid or gas, the concentration and composition of the pollutants, and the contact time between the pollutants and the biosorbent [ 12 , 13 , 14 , 19 , 24 , 27 , 28 , 29 , 30 ]. The advantages of biosorption in a dynamic regime include: low cost, high efficiency, and ability to remove a wide range of pollutants.…”

“…To reduce channeling and to improve fouling resistance, fluidized bed systems are used. They are more efficient as they allow an increased mass transfer (the biosorbent fluidization in the column creates a high surface-area-to-volume ratio and improves contact with the wastewater and are much easier to scale up, being suitable for a wide range of treatment applications [ 29 , 30 , 32 , 34 ].…”

The use of residual microbial biomass from various industries in emerging pollutant removal strategies represents a new area of research in the field. In this case, we examined how to remove reactive dyes from an aqueous solution utilizing a biosorbent made of residual biomass from immobilized Saccharomyces pastorianus (S. pastorianus) in a polymer matrix using a dynamic system. Fluidized bed column biosorption investigations were carried out on a laboratory scale. Brilliant Red HE-3B was chosen as the target molecule. The main parameters considered for this purpose were the flow rate (4.0 mL/min; 6.1 mL/min), initial pollutant concentration (51.2 mg/L; 77.84 mg/L), and biosorbent mass (16 g; 20 g). The experimental data of the fluidized bed study were evaluated by mathematical modeling. The Yoon–Nelson, Bohart–Adams, Clark, and Yan models were investigated for an appropriate correlation with the experimental data. An acceptable fit was obtained for a flow rate of 4 mL/min, an initial pollutant concentration of 51.2 mg/L, and a biosorbent amount of 20 g. The obtained results indicate that the biosorbent can be used efficiently in a dynamic system both for the removal of the studied dye and in extended operations with a continuous flow of wastewater. As a conclusion, the investigated biocomposite material can be considered a viable biosorbent for testing in the removal of reactive dyes from aqueous environments and creates the necessary conditions for the extension of studies toward the application of these types of biosorbents in the treatment of industrial effluents loaded with organic dyes.
