In this work, the removal of dye using thermally modified sludge from a drinking water treatment facility (DWTS) was evaluated. This study gives value to waste coagulation flocculation process (waste sludge) in order remove an emerging organic agent (Bordeaux B). The sustainability leads circular economy, which represents important environmental contribution. physicochemical characterization DWTS carried out by standard methods. DRX and FTIR spectroscopy, SEM, superficial specific area SBET N2 at 77 K were used. Thermal activation processes (200–600 °C) obtain best activated thermal conditions for (T: 500 °C). Muscovite other minerals found DWTS. Experimental (batch mode) determined: contact time (CT), pH, adsorbent dose (AD), initial concentration (Co). = 54.77 67.90 m2/g TA-500. efficiency achieved °C (R 85.57 ± 0.76 %, q max 37.45 0.14 mg/g), which, compared unconventional adsorbents, is more reliable competitive. adsorption adjusted Langmuir mathematics model, following pseudo-second-order kinetics (R2 0.99).

In this study, we utilized drinking water treatment sludge (WTS) to produce adsorbents through the drying and calcination process. These were then evaluated for their ability remove azithromycin (AZT) from aqueous solutions. The L-500 adsorbent, derived (at 500°C) of WTS generated under conditions low turbidity in plant, presented an increase specific surface area 70.745 95.471 m 2 g -1 total pore volume 0.154 0.211 cm 3 , which resulted a significant AZT removal efficiency 65% distilled after 60 min treatment. synthetic wastewater, rate increased 80%, comparison, real effluent municipal wastewater 56% was obtained. Kinetic studies revealed that experimental data followed pseudo-second-order model (R : 0.993–0.999, APE: 0.07–1.30%, Δq: 0.10–2.14%) suggesting chemisorption is limiting step adsorption using L-500. This finding aligns with FTIR analysis, indicates mechanisms involve π-π stacking, hydrogen bonding, electrostatic interactions. equilibrium analyzed nonlinear Langmuir, Freundlich, Langmuir-Freundlich isotherms. best fitting 0.93, 2.22%, 0.06%) revealing numerous interactions energies between adsorbent showed reduction 19% its four consecutive reuse cycles. line circular economy principles, our study presents interesting prospect valorization WTS. approach not only offers effective but also represents forward advancing sustainable solutions within framework economy.
