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 ...
1. The characteristics of hospital sewage Hospital waste water contains some special pollutants, such as drugs, disinfectants, diagnostic agents, detergents, and a large number of pathogenic microorganisms, parasite eggs and various viruses (such as roundworm eggs, hepatitis virus, tuberculosis and dysentery) . In addition, there are radioactive substances such as radium 226, phosphorus, gold ...
In this study, the degradations of 2,3,4,5,6-pentabromotoluene (PBT), 2,3,4,5,6-pentabromoethyl benzene (PBEB), triclosan (TCS) and gemfibrozil (GFZ) in raw hospital wastewater were investigated with cerium (IV) oxide and titanium (IV) oxide nanoparticles considering the mechanisms of adsorption, photolysis, and photocatalysis with UV-C lamps. The effects of nano-CeO2 and nano-TiO2 ...
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 ...
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 ...
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 ...
The Bremen Overseas Research and Development Association (BORDA) has a mission to improve the living conditions of disadvantaged communities and to preserve the environment through decentralized sanitation projects. As part of this mission, the Association has developed modular, decentralized, and cost-effective wastewater treatment service packages that ...
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 ...
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) ...
A global market-leading manufacturer of mechanical fastening systems and precision components needed to reduce wastewater disposal costs. The Italian facility serves diversified end markets, including the automotive, construction supply, electrical/electronics, aerospace and medical components industry. Project Goals: 1) Reclaim and reuse oily wastewater from cleaning tunnels (Dürr ...
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 ...
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 ...

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 ...
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 ...
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 ...
Extracellular DNA in municipal wastewater and effluents from hospitals and R&D laboratories contains antimicrobial resistance and recombinant genes that are today considered as a new class of emerging contaminants. The objective of this research was to investigate the effect of disinfection agents on the integrity of DNA molecules by using real-time PCR. Escherichia coli cell suspensions and ...

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 ...
The objective of this study has been to develop technologies that can reduce the content of active pharmaceutical ingredients (APIs) and bacteria from hospital wastewater. The results from the laboratory- and pilot-scale testings showed that efficient removal of the vast majority of APIs could be achieved by a membrane bioreactor (MBR) followed by ozone, ozone + hydrogen peroxide or ...
