Characterisation of medical-waste sterilisation-plant wastewater and a preliminary study of coagulation–flocculation treatment options

Wastewater from a medical-waste sterilisation plant (MWSP) contains unique pollutants and requires on-site treatment to prevent contamination of the municipal sewage system and receiving water bodies. Therefore, to meet the prescribed discharge standards and comply with the legal regulations, pre-treatment must be applied to MWSP wastewater. In this study, the capabilities of ...

Decentralized Wastewater Treatment System for LORMA Medical Center – San Fernando City: A LORMA-funded Project to Better Manage its Wastewater

In cities lacking a centralized sewerage system, hospitals can pose a significant sanitation threat. Their often high population of patients and staff creates a large wastewater problem that could easily overwhelm a normal septic tank. Worse yet, the wastewater generated is often much higher in pathogen levels, due to the waste outputs of infected patients. Thus, hospitals need to take a ...

The contribution of pharmaceutically‐active compounds from healthcare facilities to a receiving sewage treatment plant in Canada

Concentrations and percent loadings of pharmaceutically‐active compounds (PhACs) and other emerging contaminants (ECs) released from healthcare facilities (2 hospitals and a long‐term‐care facility) to a sewage treatment plant (STP) in a large urban sewershed was evaluated. An additional hospital outside the sewershed was also monitored. Fourteen of the 24 steroids /hormones and 88 of the 117 ...

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 ...

Management of hospital wastewaters: the case of the effluent of a large hospital situated in a small town

Hospitals are the main source of pharmaceutical compounds (PhCs) released into the environment. Generally, their discharges are co-treated with domestic wastewaters, resulting in a decrement of the recalcitrant compound concentrations in the final effluent due to water dilution. However, as many PhCs resist normal treatments, pollutant load does not change. This paper compares the chemical ...

Modeling of hospital wastewater pollution by pharmaceuticals: first results of Mediflux study carried out in three French hospitals

A study has been carried out in three French hospitals in order to assess and model the pharmaceutical load in hospital wastewater and its impact in WWTP. This study, called Mediflux, consisted of three successive steps: first, an original prioritization procedure developed in our laboratory enabled us to select a list of relevant molecules from different Anatomical Therapeutic Chemical (ATC) ...

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 ...

Quality and quantity survey of hospital wastewaters in hormozgan province

Nowadays in many societies, access to healthy water and the amount of water consumption are considered as aspects of sanitation situation and development of societies. The consumed water in daily life is recycled to primary source in some ways, but it is in the form of a liquid containing the consumed water and different contaminants that are entered during consumption. One of the important ...

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 ...

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 ...
