“…However, conventional treatment (based mainly on mechanical and biological processes) is not efficient enough [49][50][51]. New treatment processes (see examples in Table 4) include various membrane bioreactors, nanomaterials, ferrates, Fenton reaction, ozonation, heterogeneous catalysis, ultrasound, aquatic plants, and adsorption e.g., on biochar or activated carbon [51][52][53][54]. Hospital wastewaters often contain significant amounts of fecal coliforms, which exhibit resistant or multi-resistant properties to various types of antibiotics [52,53,[58][59][60].…”

Hospital wastewaters often contain significant amounts of fecal coliforms, which exhibit resistant or multi-resistant properties to various types of antibiotics [52,53,[58][59][60]. Therefore, the degradation processes are investigated in terms of removal efficiency not only for a wide range of micropollutants but also for pathogenic microorganisms, so the disinfection ability is evaluated [61,62].…”

Municipal wastewaters can generally provide real-time information on drug consumption, the incidence of specific diseases, or establish exposure to certain agents and determine some lifestyle consequences. From this point of view, wastewater-based epidemiology represents a modern diagnostic tool for describing the health status of a certain part of the population in a specific region. Hospital wastewater is a complex mixture of pharmaceuticals, illegal drugs, and their metabolites as well as different susceptible and antibiotic-resistant microorganisms, including viruses. Many studies pointed out that wastewater from healthcare facilities (including hospital wastewater), significantly contributes to higher loads of micropollutants, including bacteria and viruses, in municipal wastewater. In addition, such a mixture can increase the selective pressure on bacteria, thus contributing to the development and dissemination of antimicrobial resistance. Because many pharmaceuticals, drugs, and microorganisms can pass through wastewater treatment plants without any significant change in their structure and toxicity and enter surface waters, treatment technologies need to be improved. This short review summarizes the recent knowledge from studies on micropollutants, pathogens, antibiotic-resistant bacteria, and viruses (including SARS-CoV-2) in wastewater from healthcare facilities. It also proposes several possibilities for improving the wastewater treatment process in terms of efficiency as well as economy.

“…COVID-19 pandemic contributes and enhances development and dissemination of antibiotic resistance due to widespread biocide use and increased consumption of antibiotics also by COVID 19 patients. From this point of view, efficient disinfection of wastewater is needed [ 5 ]. The presence of viruses and their fragments in wastewaters raises considerable concern due to their ability of possible resistance to disinfection procedures [ 6 ].…”

“…Recently, in addition to pure ferrate(VI), various water soluble polymeric capsules containing ferrate(VI) powder were designed [ 25 , 26 ]. Capsules were used for wastewater treatment not only in the case of various pharmaceuticals (efficiency over 80%), but also for antibiotic resistant bacteria elimination with promising results (complete removal) [ 5 , 25 ]. During the current pandemic situation, the issue of the virus occurrence in wastewater arises as a risk factor for spreading of infectious diseases.…”

Waterborne pathogens including viruses, bacteria and micropollutants secreted from population can spread through the sewerage system. In this study, the efficiency of unique effervescent ferrate-based tablets was evaluated for total RNA and DNA removal, disinfection and degradation of micropollutants in hospital wastewater. For the purpose of testing, proposed tablets (based on citric acid or sodium dihydrogen phosphate) were used for various types of hospital wastewater with specific biological and chemical contamination. Total RNA destruction efficiency using tablets was 70–100% depending on the type of acidic component. DNA destruction efficiency was lower on the level 51–94% depending on the type of acidic component. In addition, our study confirms that effervescent ferrate-based tablets are able to efficiently remove of SARS-CoV-2 RNA from wastewater. Degradation of often detected micropollutants (antiepileptic, antidepressant, antihistamine, hypertensive and their metabolites) was dependent on the type of detected pharmaceuticals and on the acidic component used. Sodium dihydrogen phosphate based tablet appeared to be more effective than citric acid based tablet and removed some pharmaceuticals with efficiency higher than 97%. Last but not least, the disinfection ability was also verified. Tableted ferrates were confirmed to be an effective disinfectant and no resistant microorganisms were observed after treatment. Total and antibiotic resistant bacteria (coliforms and enterococci) were determined by cultivation on diagnostic selective agar growth media.

This work compares the prevalence of antibiotic resistant coliform bacteria in hospital wastewater effluents in Slovak (SR) and Czech Republic (ČR). It also describes selected antibiotic resistant isolates in view of resistance mechanism and virulence factor. The highest number of multidrug resistant bacteria was detected in samples from the hospital in Valašské Meziříčí (ČR). More than half of resistant isolates showed multidrug resistance phenotype as well as strong ability to form biofilm. In 42% of isolates efflux pump overproduction was detected together with tetA and tetE genes. The production of extended-spectrum β-lactamases in coliform isolates was encoded mainly by blaTEM, blaCTX-M-2 and blaCTX-M-8/25 genes. About 62% of resistants contained a combination of two or more extended spectrum beta-lactamases (ESBL) genes. Our results strengthen the fact that hospital effluents are a source of multidrug resistant bacteria which can spread their resistance genes to other bacteria in wastewater treatment plants (WWTPs). Accordingly, hospital wastewater should be better treated before it enters urban sewerage.
