Summary: Factors affecting the adsorption of diclofenac on sewage sludge were evaluated in this study. Over 80% diclofenac was removed at an initial concentration of 1 mg/L. Adsorption increased at higher concentrations, and more than 99% of diclofenac was adsorbed at a concentration of 100 mg/L. Significant removal of diclofenac was observed after 5 minutes of contact time, and the adsorption efficacy was over 98% after 50 and 60 minutes. The results of pseudo-first and second order kinetics showed a reasonable regression value, indicating a good fit for the model. Diclofenac adsorption was more effective at acidic pH levels than alkaline levels. The sludge samples contained multi-drug resistant bacteria, including vancomycin-resistant entemcoccus stains, methicillin-resistant Staphylococcus aureus positive strains, and extended-spectrum betal-lactamaseharbouring Entembacteriacea. Klebsiella pneumoniae, E. coli, and Enterobacter were among the drug-resistant Entembacteriaceae strains found. In conclusion, activated sludge can effectively be used for the removal of diclofenac from wastewater.

Summary: This study experimentally elucidated the role of extracellular polymeric substances (EPS) in minimizing excess sludge yield in tannery wastewater treatment using a hybrid activated sludge system (MANODOX). The results showed that the MANODOX system significantly reduced sludge yield compared to the conventional p-CAS system, with lowered EPS accumulation and sludge generation. The strict maintenance of sludge retention time and the stimulation of cell-lysis in the MANODOX system were identified as key factors in influencing floc characteristics and EPS degradation.

Summary: This article reports a long-term (2.5-year) full-scale study conducted in two activated sludge wastewater treatment plants (WWTPs) to investigate practical strategies for controlling pharmaceutical compounds (PhCs). The results showed that some of the most abundant influent PhCs were highly removed, while others had variable removals and some were recalcitrant. The study established a 4-class PhC framework based on biodegradation and solid-water distribution, which was particularly sensitive to the biodegradation rate. Statistical analysis revealed key operational variables and highlighted the importance of optimizing conditions for nitrifiers to improve PhC control.

Summary: HMF deteriorates the removal performance of activated sludge, reducing the removal rates of COD, TP and NH4+-N, while increasing EPS content and affecting the settleability and dewatering capacity of activated sludge. HMF also inhibits dehydrogenase activity in activated sludge and alters microbial functions. Microbial community analysis shows that some microbes are adversely affected by HMF while others better tolerate it.
