“…Continuous biosorption experiments were performed at ambient temperature, in a fixed‐bed column (in a simple glass with a length of 12.5 cm, and an internal diameter of 1 cm) filled with a fixed quantity of CVR with a particle size distribution ranged between 0.31 and 0.4 mm (Turkman et al, 2019). At the bottom of the column, a glass sieve was attached and a glass wall was connected to it, to prevent the leaking of the sorbent, which may clog the drainage area (Thirunavukkarasu et al, 2021). Also at the top of the column, a glass wall was placed.…”

“…Numerous studies on the copper removal by biosorption in discontinuous and/or continuous modes (fixed bed columns) on biosorbents based on various natural or modified biomasses were performed (Kajeiou et al, 2020; Song et al, 2014; Xavier et al, 2018). Biosorption on continuous mode remains an attractive method because it allows more efficient use of sorbent capacity (Thirunavukkarasu et al, 2021). However, the effective design of a column sorption system requires the expectation of the profiles (concentration‐time) that are also called breakthrough curves (Gutiérrez‐Ortiza et al, 2019).…”

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.

“…Typically, fixed bed technology operates as a function of bed height and adsorbate flow rate, which are used to construct breakthrough curves for subsequent analysis. While evaluating the purification process via column studies is more practical than batch studies, this does not negate the importance of batch studies (Thirunavukkarasu et al 2021 ).…”

“…In a fixed-bed system, the inlet flow rate significantly affects the profile of the breakthrough curve due to variations in the feed superficial velocity and interaction time. Reduced flow rates maximise the interaction time between the feed solution and the packed biochar, ensuring a sufficient residence time for adsorption (Thirunavukkarasu et al 2021 ). Jung et al investigated the adsorption performance of electrochemically modified biochar calcium-alginate beads towards phosphate at flow rates of 2.5, 5.0, and 7.5 mL min −1 , with a fixed amount of biochar and a fixed concentration of primary phosphate.…”

In the context of climate change and the circular economy, biochar has recently found many applications in various sectors as a versatile and recycled material. Here, we review application of biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, and energy storage. The ultimate storage reservoirs for biochar are soils, civil infrastructure, and landfills. Biochar-based fertilisers, which combine traditional fertilisers with biochar as a nutrient carrier, are promising in agronomy. The use of biochar as a feed additive for animals shows benefits in terms of animal growth, gut microbiota, reduced enteric methane production, egg yield, and endo-toxicant mitigation. Biochar enhances anaerobic digestion operations, primarily for biogas generation and upgrading, performance and sustainability, and the mitigation of inhibitory impurities. In composts, biochar controls the release of greenhouse gases and enhances microbial activity. Co-composted biochar improves soil properties and enhances crop productivity. Pristine and engineered biochar can also be employed for water and soil remediation to remove pollutants. In construction, biochar can be added to cement or asphalt, thus conferring structural and functional advantages. Incorporating biochar in biocomposites improves insulation, electromagnetic radiation protection and moisture control. Finally, synthesising biochar-based materials for energy storage applications requires additional functionalisation.

“…Biosorption is a significantly more proficient strategy for the elimination of numerous pollutants, which include heavy metals, because of the accessibility of a diverse range of biosorbents that have low prices and adapt to various circumstances [21][22][23][24]. In this way, different sorts of microorganisms (bacteria, yeasts, algae, fungi) [25][26][27] have affirmed that they can recover heavy metals from aqueous solutions via biosorption [7,[27][28][29].…”

The examination of the performance of raw and immobilized S. (Saccharomyces) cerevisiae in the simultaneous abatement of metal ions from wastewater effluent is the focal point of this article. The optimal storage time for raw and immobilized S. cerevisiae, during which they can be utilized, was estimated. The outcomes revealed that as the initial metal ion concentrations increased, the adsorption capacity improved, while the removal efficiency of S. cerevisiae yeast cells decreased, with the highest uptake obtained at the optimal conditions: pH = 5.0, 2.0 g S. cerevisiae/L, 25 °C, and a contact time of 25 min. The maximum adsorption capacities (qmax) for Pb(II), Cd(II), and Ni(II) ions are shown by Langmuir at 65, 90, and 51 mg/g, respectively. It was discovered that the metal ions’ biosorption reactions were spontaneous and were fitted by the pseudo-second-order model. The mechanisms of the metal ions’ abatement were explained by using XRD (X-ray diffraction), FTIR (Fourier transform infrared spectroscopy), (BET) Brunauer–Emmett–Teller, and TEM (transmission electron microscopy) outputs. EDTA and citric acid can eliminate more than 70 ± 4 and 90 ± 5% of the adsorbed ions, respectively. The experiment of storage demonstrated that the immobilized S. cerevisiae was more stable for 8 months than the raw yeast.
