“…Yan model showed the highest average of the determination coefficients (R 2 = 0.9842) of all experiments, while the amounts adsorbed by the packed column were better predicted by Thomas equation (Franco et al 2018). The adsorption of ranitidine hydrochloride (RH) onto microwave-irradiated Aegle marmelos Correa fruit shell was also investigated in a fixed-bed column (Sivarajasekar et al 2018). The removal of total organic carbon from real industrial waste water using polyethylenimine-functionalized pyroxene nanoparticles (PEI-PY) embedded into diatomite by Hethnawi et al (2017).…”

Present paper involved the review of fixed-bed column studies for removal of various contaminants from synthetic wastewater. Basic concept of adsorption, its types (i.e., chemisorption and physisorption) and its mechanism, adsorbents and adsorbates were included. Comparison of batch and column adsorption study is mentioned. Complete study of breakthrough curve for designing adsorptive column is interpreted. This paper explicates the detailed explanation of various process parameters and isotherm models for column study. Fixed-bed adsorption studies using various adsorbates, i.e., metal, ion, dye and other hazardous materials, are reviewed, in which adsorption of chromium metal is most exploitable. Conclusion and some challenges for utilization in real world are also exposed.

“…Three factors namely, NaOH concentration (0.25-0.75 M, X 1 ), initial norfloxacin concentration (25-75 mg/L, X 2 ) and saponin concentration (0.01-0.03 g/100 mL, X 3 ) were considered to analyse the extraction efficiency of norfloxacin from aqueous solution. In order to investigate the combined effects of the selected variable on percentage norfloxacin removal the experiments were carried out according to the BBD [26][27][28][29]. The results for BBD are shown in Table 1.…”

Amongst the present water treatment technologies membrane separation is gaining focus nowadays. Emulsion liquid membrane is one of the advanced strategies used for pollution removal from waste water in which the use of biosurfactant makes this approach eco-friendly technique. The norfloxacin belongs to the fluoroquinolones class of antibiotic and extensively used for urinary tract infections, which is the model pollutant in this study. Saponin was solvent extracted from soapnuts and used as biosurfactant. The main and interactive effects of parameters such as saponin concentration (0.01-0.03 g/100 mL), NaOH concentration (0.25-0.75 M) and Initial Norfloxacin concentration (25-75 mg/L) were investigated using Response Surface Methodology (RSM)-Box Behnken Design (BBD) and Artificial Neural Networks (ANN) design. The results suggested that developed 3-8-1 ANN model evaluated in terms of performance measure (R 2 : 0.9806, Chi square: 0.02) and error functions (RMSE: 0.11, MAE: 0.09, SEP: 1.16, MPE: 1.76) demonstrated superiority more precisely than the RSM model in terms of both data fitting and prediction capability. The optimal conditions for ELM were found to be: initial norfloxacin concentration 67.65 mg/L, saponin concentration 0.021 mg/100 mL, and NaOH concentration 0.36 M and the extraction efficiency at these parameter settings would be 91.27%.

“…In batch mode operation, variables affecting the removal process such as pH, adsorbent dose, initial concentration of the contaminant, and contact time have also been optimised (El-Azazy et al 2020 ; El-Azazy et al 2021b ; El-Azazy et al 2021c ; Bardestani et al 2019 ; Beakou et al 2017 ; Kalderis et al 2017 ; Lenin Sundar et al 2021 ; Roy et al 2018 ; Turk Sekulic et al 2018 ; Zhao et al 2021d ). Variables such as fixed-bed height, flow rate, the particle size of the biochar adsorbent, pH, and concentration of the inlet solution are optimised in continuous mode operation (Biswas et al 2020 ; Blagojev et al 2019 ; Levio-Raiman et al 2021 ; Sivarajasekar et al 2018 ; Suárez‐Vázquez et al 2021 ). As a result, the target response (output) will vary according to the input variables assessed.…”

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.
