Scope of the present study was the comparison of two advanced water treatment technologies – ozonation and powdered activated carbon adsorption (PAC) – with respect to the elimination of emerging contaminants. Main objective was the assessment of synergistic effects arising from the combination of both technologies in one wastewater treatment plant. The study was conducted at a full-scale plant...

The Pseudomonas aeruginosa-containing wastewater released by hospitals is treated by wastewater treatment plants (WWTPs), generating sludge, which is used as a fertilizer, and effluent, which is discharged into rivers. We evaluated the risk of dissemination of antibiotic-resistant P. aeruginosa (AR-PA) from the hospital to the environment via the wastewater network. Over a 10-week period, we sa...

There is growing evidence that patients with Clostridiumdifficile-associated diarrhoea often acquire their infecting strain before hospital admission. Wastewater is known to be a potential source of surface water that is contaminated with C. difficile spores. Here, we describe a study that used genome sequencing to compare C. difficile isolated from multiple wastewater treatment plants across t...

BACKGROUND Carbapenemase-producing Enterobacteriaceae (CPE) are an emerging infection control problem in hospitals worldwide. Identifying carriers may help reduce potential spread and infections. AIM To assess whether testing hospital wastewater for CPE can supplement patient-based screening for infection prevention purposes in a hospital without a recognized endemic CPE problem. METHODS Wa...

The bacteriological and physiochemical qualities of hospital wastewater discharged into the environment from University of Benin Teaching Hospital (UBTH), Benin City was investigated to assess the influence of the hospital wastewater in the receiving environment. The bacteriological parameters were carried out using the standard microbiological techniques. The bacteriological parameters examine...

Background & Aims of the Study: The most important compounds in hospital wastewater are antibiotics, disinfectants, anesthetics, radioactive elements, static cytotoxic agents, other chemicals and hazardous materials that caused to be different domestic sewage. The purpose of this study was the evaluation of performance of extended aeration biological system in pollutants remova...

Pharmaceuticals in wastewater have clearly raised concern and a broad range of analytical methods has been used to assess the risk as accurately as possible. The aim of our study was to measure and compare the concentrations of atorvastatin, bisoprolol, carbamazepine, ciprofloxacin, clofibric acid, diclofenac, fluoxetine, metoprolol, and sertraline in wastewater samples taken from one municipal...

background & aims of the study: antibiotics utilize with the aim of improving human, animal and plant health; also, for treating infections caused by pathogenic bacteria. when these compounds introduce into ecosystems, could affect the microbial community and jeopardize human health. therefore, the aim of present study is to determination of the presence of six common utilized antibiotics (amox...
