Summary: Pharmaceuticals are at the forefront of environmental research due to their complex bioactivity, and conventional wastewater treatment methods are inadequate for their removal. Advanced oxidation processes offer efficient solutions for pharmaceutical degradation, but face challenges with operating costs. Combining AOPs with biological treatments can provide a comprehensive solution for complete pharmaceutical degradation with advantages including low energy costs and generation of non-toxic by-products.

Summary: Extracellular antibiotic resistance genes (eARG) play a crucial role in the spread of antimicrobial resistance (AMR) in wastewater treatment and aquatic environments. Membrane bioreactors (MBRs) are more effective at removing ARGs from wastewater compared to traditional activated sludge processes. However, the removal of eARGs may be limited by their size, preventing them from passing through microfiltration (MF) membranes.

Summary: The clinoptilolite zeolite has been tested for its ability to remove lead from polluted groundwater in water wells. Batch and fixed-bed column experiments were conducted to assess its performance. The results showed that the highest lead removal efficiency was achieved at pH = 6 and 298 K within 90 minutes. The Freundlich model accurately predicted the adsorption behavior, and the pseudo-second order equation was the best-fitting kinetic model for clinoptilolite. Column experiments indicated that a flow rate of 1 mL/min, a bed height of 10 cm, and a grain size of 0.6 to 0.8 mm resulted in the highest removal efficiency. The Thomas and Yoon-Nelson models accurately predicted the breakthrough curves.
