“…They illustrate the variation of copper concentration along the column for a value of Q of 1 ml min −1 . Next to each image, a color scale is shown; it depicts the equivalent concentration value according to the color (Vera et al, 2021). The predicted concentrations solved numerically indicate that after passing of the copper solution through CVR in the fixed bed column, the biosorbent CVR sorbs copper until saturation time.…”

The main purpose of this investigation is to model the results related to biosorption using COMSOL (Multiphysics 4.3a), and to solve the advection‐dispersion equation by using both linear and Langmuir models. A bidimensional model was then proposed to study the mass transfer in the process of copper ions sorption in a dynamic mode on cider vinegar residues. Sorption tests were realized by evaluating the influence of flow rate (0.75, 1, and 2.65 ml min−1), bed height (3.5, 7 and 8.5 cm), and copper initial concentration (169 and 300 mg L−1). For all cases, the mathematical formulation was solved by assuming that the column is homogeneous and the sorption is instantaneous. The corresponding results were exploited through breakthrough curve profiles, where it was shown that the solutions obtained by the “Langmuir COMSOL” model coincide with the experimental values. In contrast, the linear model has been unable to fit them. The optimal results were analyzed by Thomas, Adam‐Bohart Yoon Nelson, and Ogata‐Bank models, which proves that the Thomas method is well adapted with a satisfactory correlation coefficient (0.93). Further, the model validation was performed by determining the residual root mean square error, which was found less than 0.3, thereby indicating a reasonable concordance between the estimated and experimental points. The high sorption capacity obtained was around of 41.37 mg g−1, which suggests that the cider vinegar residues can be exploited as a low‐cost, available, and effective sorbent biomass in the field of the treatment of industrial effluents. Practitioner Points Cider vinegar residues (CVR) as low cost biosorbent were studied for continuous biosorption. A successful COMSOL model was proposed and validated. CVR is an effective biosorbent for copper fixed bed biosorption. High sorption capacity was around of 41.37 mg g−1 under optimal conditions.

“…These tools are used to screen a vast array of materials, including metal-organic frameworks (MOFs), to identify the most effective adsorbent candidates. MOFs, with their customizable structures and functionalities, have shown great promise in adsorption applications due to their high porosity and tunable chemical properties [ 40 ].…”

“…In fact, there is a consensus that improving material properties alone is not sufficient to realize next-generation separations systems. , Yet, promising materials are rarely evaluated in the context of a process at scale to assess feasibility, economics, and sustainability for specific applications. , Instead, modeling efforts are often siloed to traditional domains and length scales. For example, equilibrium models , and fluid dynamics equations , are used to study the evolution of concentration profiles in adsorption systems, with model parameters estimated by fitting data obtained from bench-scale column tests to the model predictions . Scale-up is then achieved by increasing the throughput and sorbent mass loading by resizing the bench-scale equipment while keeping the operating velocity and theoretical plate height constant and minimizing mass-transfer resistances defined using empirical correlations. , On the process scale, partial differential algebraic equation-constrained optimization is used to synthesize the best regeneration cycles for pressure swing adsorption, simulated moving beds, and similar processes for given application specifications. − None of these adsorption modeling paradigms facilitate rapid assessment of new materials in the context of specific separation applications.…”

Material Property Targets to Enable Adsorptive Water Treatment and Resource Recovery Systems

Novel separation technologies are necessary to use Earth's limited resources while maintaining a high standard of living. The availability of potable water is stressed due to contamination with trace elements such as lead (Pb). The demand for lithium (Li) due to vehicle electrification will exceed its supply from primarily brine sources within a decade. Adsorption processes are promising cost-effective solutions to challenging low-concentration separations. Yet, there is a lack of quantitative modeling to assess emerging sorbents, which hinders the translation of novel materials into transformative technologies. This work proposes a generalized multiscale process targeting framework to rapidly screen candidate sorbents and set material property targets to develop adsorptive systems including Pb remediation and Li recovery applications. Langmuir isotherm and sorbent structure–property calculations explicitly link molecular properties, including affinity, saturation capacity, and pore size; device design decisions, including sorbent cross-sectional area and bed length; and system design decisions, including sorbent mass and number of parallel beds. The framework predicts that for Pb removal, there is limited scope to improve materials in isolation; instead, integration of sorbents into devices (e.g., membranes, packed beds) may be the larger barrier to realizing future technologies. Similarly, for Li recovery applications, improved materials processing techniques have the potential to accelerate the process. Moreover, the Li case study demonstrates the utility of the framework based on dimensionless formulas as an easy-to-use tool for the broader membrane science and environmental engineering communities to assess the feasibility of emerging materials to meet process demands. Finally, these dimensionless models are used to identify three distinct regions of relative performance between batch and semicontinuous processes. These results give caution to applying scale-up heuristics outside their valid region, which can lead to under- or overdesign during bottom-up studies from the bench to the process scale. The presented targeting framework bridges a crucial gap between material and technology development by identifying the potential for optimized materials processing and device design techniques to fully utilize the characteristics of emerging materials for sustainable separations of the future.
