Intrinsic kinetics for fixed bed bioreactor in hospital wastewater treatment

Variation in hospital wastewater (HWW) pollutants and differences with municipal wastewater (MWW), make the use of biokinetic coefficients obtained from activated sludge in the MWW treatment unprofitable for designing, modeling and evaluation of biological processes for HWW treatment. Since this study was conducted to evaluate the performance and biokinetic coefficients of a fixed bed ...

Virulence and plasmidic resistance determinants of <italic>Escherichia coli</italic> isolated from municipal and hospital wastewater treatment plants

Virulence and plasmidic resistance determinants of Escherichia coli isolated from municipal and hospital wastewater treatment plants

Escherichia coli is simultaneously an indicator of water contamination and a human pathogen. This study aimed to characterize the virulence and resistance of E. coli from municipal and hospital wastewater treatment plants (WWTPs) in central Portugal. From a total of 193 isolates showing reduced susceptibility to cefotaxime and/or nalidixic acid, 20 E. coli with genetically distinct fingerprint ...

Treatment of hospital wastewater effluent by nanofiltration and reverse osmosis

Considerable concern exists regarding the appearance and effects of trace and ultra trace pollutants in the aquatic environment. In this context, it is necessary to identify relevant hot spot wastewater – such as hospital wastewater – and to implement specific wastewater treatment solutions. Membrane bioreactor (MBR) technology seems to be a suitable pre-treatment approach for the subsequent ...

The impacts of sea-level rise on the California coast

Over the past century, sea level has risen nearly eight inches along the California coast, and general circulation model scenarios suggest very substantial increases in sea level as a significant impact of climate change over the coming century. This study includes a detailed analysis of the current population, infrastructure, and property at risk from projected sealevel rise if no actions are ...

Study on wastewater treatment systems in hospitals of Iran

Water resources shortage is one of the most important issues due to the population growth and ever increasing water demands as well as its conservation. Wastewater treatment can serve as a logical way to recycle water to consumption cycle. Due to variety of water uses, it seems that there are certain treatment techniques for different types of wastewater, such as municipal and hospital ...

Ranking Prescribed Pharmaceuticals in Terms of Environmental Risk: Inclusion of Hospital Data and the Importance of Regular Review

A newly available dataset on pharmaceuticals used in Scottish hospitals enabled an Environmental Risk Assessment that includes hospital consumption of pharmaceuticals, as previous UK rankings have been based on community prescription only. As health and the environment are devolved issues for the Scottish government, it is in any case merited to consider a Scottish ranking separately; regional ...

Discharge of pharmaceuticals into municipal sewers from hospitals and long-term care facilities

The presence of pharmaceutically active compounds in the aquatic environment has become well established, and their presence is of potential concern because they are designed to produce biological response in the target receptor, may bear intrinsic toxicity (e.g. cytostatic agents, antibiotics) and they possess the potential to foster and maintain drug resistance. For both risk assessment and ...

Survival of antibacterial resistance microbes in hospital-generated recycled wastewater

Hospital wastewater has the potential to be a threat to the hospital environment as it can contain pathogenic bacteria that may facilitate the resistant nature of organisms within effluent or water treatment plants. The recycling of hospital wastewater should have good quality. This study was carried out to highlight the incidence of antibiotic resistant bacteria in hospital-generated ...
