Given the increasing pressure on water bodies, it is imperative to explore sustainable methodologies for wastewater treatment and reuse. The simultaneous presence of multiples contaminants in complex wastewater, such as liquid effluents from biogas plants, can compromise biological effectiveness reclaiming water. Vertical subsurface flow constructed wetlands were established low-cost decentralized technologies treat fraction digestate municipal organic waste with metals, antibiotics, antibiotic resistance genes, allow its reuse irrigation. Twelve lab-scale planted assembled gravel, light expanded clay aggregate sand, testing four different treating conditions (liquid spiked oxytetracycline, sulfadiazine, or ofloxacin, at 100 μg/ L, without dosing) during 3 months. Physicochemical parameters (pH, chemical oxygen demand (COD), nutrients, antibiotics), microbial communities dynamics (through 16S high-throughput sequencing) genes removal (qPCR) monitored influents effluents. Systems removed 85.8%–96.9% matter (as COD), over 98.1% ammonium phosphate ions, 69.3%–99.4% nitrate nitrite no significant differences between absence antibiotics. Removal Fe, Mn, Zn, Cu, Pb Cr exceeded 82% all cycles. also sulfadiazine ofloxacin 99%, decreased intl1, tetA, tetW , sul1 qnrS gene copies. Nonetheless, after months dosing, started being detected. processes relied high HRT (14 days) various mechanisms including sorption, biodegradation, precipitation. Microbial community diversity changed significantly a decrease initial Firmicutes dominance, but clear effect antibiotics structure. Removals above 85% 94% observed Streptococcus Clostridium, respectively. Results suggest that vertical suitable technology irrigation agricultural systems, contributing circular bioeconomy concept. However, more profound understanding effective strategies needed avoid dissemination.

This study presents a successful synthesis of natural magnetic silica (NMM@SiO2) materials modified with hydrophobic groups for the adsorption two antibiotics, chloramphenicol (CAP) and ciprofloxacin (CIP). The NMM@SiO2 was prepared using material (NMM) isolated from iron sand, extracted quart methyltrimethoxysilane (MTMS) as precursor. synthesized were characterized various analytical techniques, including FTIR, XRD, VSM, TGA, TEM, SEM-EDX-Mapping. Subsequently, used to adsorb antibiotics an aqueous solution batch system, antibiotic concentration in measured UV-VIS spectrophotometry. characterization results confirmed incorporation MTMS onto NMM@SiO2. studies indicated that optimum pH CAP CIP 5 6, respectively, contact time being 120 min 90 CIP, initial concentrations 200 mg L−1. (1.5 g) 0.4 g (3.0 mmol) obtain NMM@SiO2/C1(3) exhibit highest capacities both (58.46 g−1 106.81 CIP). For tested, kinetics isotherms followed pseudo-second-order Freundlich models, respectively. thermodynamic negative ΔH (exothermic), positive ΔS (increase randomness), ΔG (spontaneous) CIP. These highlight performance this hydrophobic-based adsorbent demonstrate its potential effective aquatic environments.
