“…Advanced biological processes like MBR have received much attention in treating HWW due to their high removal efficiency of organics and ECs ( Majumder et al, 2021a ; Vo et al, 2019 ). For instance, Kovalova et al (2012) have discussed the performance of a pilot-scale MBR (effective volume of 1.2 m 3 ) installed at a hospital in Switzerland for treating the wastewater discharged from the hospital.…”

“…PhACs like ibuprofen, naproxen, trimethoprim, and sulfamethoxazole were removed with an average removal efficiency of 85%, with ibuprofen showing high removal of more than 99% ( Prasertkulsak et al, 2016 ). Vo et al (2019) studied the performance of a lab-scale sponge-MBR for treating raw HWW collected from a hospital in Vietnam ( Table S3 ). The system achieved a removal efficiency of 97% for COD, 94% for ammonia nitrogen, and 47% for TP.…”

Hospitals release significant quantities of wastewater (HWW) and biomedical waste (BMW), which hosts a wide range of contaminants that can adversely affect the environment if left untreated. The COVID-19 outbreak has further increased hospital waste generation over the past two years. In this context, a thorough literature study was carried out to reveal the negative implications of untreated hospital waste and delineate the proper ways to handle them. Conventional treatment methods can remove only 50%–70% of the emerging contaminants (ECs) present in the HWW. Still, many countries have not implemented suitable treatment methods to treat the HWW in-situ. This review presents an overview of worldwide HWW generation, regulations, and guidelines on HWW management and highlights the various treatment techniques for efficiently removing ECs from HWW. When combined with advanced oxidation processes, biological or physical treatment processes could remove around 90% of ECs. Analgesics were found to be more easily removed than antibiotics, β-blockers, and X-ray contrast media. The different environmental implications of BMW have also been highlighted. Mishandling of BMW can spread infections, deadly diseases, and hazardous waste into the environment. Hence, the different steps associated with collection to final disposal of BMW have been delineated to minimize the associated health risks. The paper circumscribes the multiple aspects of efficient hospital waste management and may be instrumental during the COVID-19 pandemic when the waste generation from all hospitals worldwide has increased significantly.

“…Interesting results have been achieved in the removal of a selection of antibiotics with the system tested by ( 32 ) consisting of an enhanced MBR (equipped with hallow fibre membranes) coupled with ozonation. The MBR system is that originally proposed by ( 33 ) and then investigated by ( 34 ) for the effluent of Trung Vuong Hospital in Vietnam.…”

Recently, investigations of hospital effluent management and treatment have not only interested research groups with acquired experience in the field but have also attracted the interest of new groups over the world. The most recent literature provides new insights into the occurrence of pharmaceuticals and other contaminants of emerging concern, pathogens, viruses, antibiotic resistant bacteria and genes in hospital effluent in various new developing and developed countries. It also provides information on the effective removal of key compounds (mainly antibiotics, analgesics, beta-blockers and chemotherapy drugs) by means of enhanced biological treatments and advanced oxidation processes. The current debate among the scientific community is mainly about the proper treatment to reduce the spread of antibiotic resistant bacteria and genes, and about the feasibility (from a technical and economic point of view) of treatment trains tested at lab and pilot scale.

“…Currently, many different methods for the treatment of wastewater from healthcare facilities are being researched, which often combine chemical and biological degradation procedures in different ways [ 63 , 64 , 65 ]. A combination of ozonation with active sorbent (e.g., activated carbon), UV-C and H 2 O 2 , MBR (membrane bioreactor), and AOPs (advanced oxidation processes) dominates [ 52 , 66 , 67 , 68 , 69 ].…”

Hospital Wastewater—Source of Specific Micropollutants, Antibiotic-Resistant Microorganisms, Viruses, and Their Elimination

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.
