“…This model assume the saturated monolayer of solutes molecules on the adsorbent surface is associated with the maximum degree of adsorption, and presupposes that both the energy of adsorption and the adsorbate. This model is suitable for single-layer adsorption, and it could be represented in the following equation (Alquzweeni et al, 2021).…”

Since organic dyes are the main component of many industrial wastes, it is necessary to be removed efficiently and instantaneously. The aim of this research focuses on the synthesizing of organoclay by modifying kaolinite with cetyl trimethyl ammonium bromide and applying it for the removal of (methyl-orange) dye from water by the mechanisms of adsorption. The effects of several parameters, mainly agitation time, water pH, adsorbent doses, and dye concentrations, on the adsorption process were optimised using the central composite design (CCD) method, which was performed using MINITAB package (version 17). Results showed that the dye was completely (100%) removed at pH of 4.0, adsorbent dose of 0.4 g, dye concentration of 50 mg/L, and agitation speed of 160 rpm. In addition, it was found that Freundlich and Sips isotherms were the best models to track lab data. Moreover, the Pseudo second order method was found to be more convenient compared to other models for studying kinetics of the sorption mechanism. For column testing, an appropriate hydraulic conductivity and reactivity were obtained by combining modificatory kaolinite and glass waste with weight proportions of 50:50. Thus, empirical simulations such as those in the kinetic model of Clark have provided satisfactory consent for using the simulated methyl orange.

“…In this sense, bioelectrochemical systems have the highest removal rate (>90%), followed by membrane bioreactors (>67%) and constructed wetlands (>63%). Other current alternatives, such as the use of Lemna minor systems, have reported elimination percentages of 100, 96 and 86.5% of antibacterials such as cefadroxil, metronidazole and cephalexin, respectively [53,54].…”

Currently, thanks to the development of sensitive analytical techniques, the presence of different emerging pollutants in aquatic ecosystems has been evidenced; however, most of them have not been submitted to any regulation so far. Among emerging contaminants, antimicrobials have received particular attention in recent decades, mainly due to the concerning development of antibiotic resistance observed in bacteria, but little is known about the toxicological and ecological impact that antimicrobials can have on aquatic ecosystems. Their high consumption in human and veterinary medicine, food-producing animals and aquaculture, as well as persistence and poor absorption have caused antimicrobials to be discharged into receiving waters, with or without prior treatment, where they have been detected at ng-mg L−1 levels with the potential to cause effects on the various organisms living within aquatic systems. This review presents the current knowledge on the occurrence of antimicrobials in aquatic ecosystems, emphasizing their occurrence in different environmental matrixes and the effects on aquatic organisms (cyanobacteria, microalgae, invertebrates and vertebrates).
