The paper presents a critical overview of the first 50 years in the evolution of the activated
sludge process. Recognition of the role of aeration and microbial activity in the purification of …

EPS can affect the migration of antibiotics in biofilm reactors, however the roles of biofilm
EPS on the fate of antibiotics and the protective mechanisms to bacterial community remain …

The occurrence and fate of antibiotics in biological wastewater treatment facilities have
given rise to significant concerns. This study assessed the effects of fluoroquinolones (FQs) …

The formation of environmental sulfonamide transformation products (TPs) has only been
investigated for very selected compounds, and their transformation pathways are …

This study investigated the chronic impact of sulfamethoxazole (SMX) on activated sludge
sustaining an enriched nitrifying biomass. For this purpose, a laboratory scale fill and draw …

With increasing production and consumption, more antibiotics are discharged into
wastewater treatment plants and generally cannot be sufficiently removed. Because of the …

Current study aimed to discover both kinetic and microbial response of activated sludge
biomass to continuous exposure to tetracycline, one of the most frequently detected …

Abstract Oxic-settling-anoxic (OSA) process is one of the promising variants that produces
lower amounts of sludge and has been applied to aerobic and nutrient removal systems …

The processes controlling antibiotics fate in ecosystems are poorly understood, yet their
presence can inhibit bacterial growth and induce the development of bacterial resistance …

The study evaluated impact of sulfamethoxazole on acetate utilization kinetics and microbial
community structure using respirometric analysis and pyrosequencing. A fill and draw …
