“…The performance of various filtration-based treatment methods in terms of removal of ECs is presented in Fig. 4 d. Furthermore, these systems have several advantages over other treatment techniques, including the ability to produce high-quality effluent with minimal sludge generation, low energy use, and operation in a wide range of pH and temperature ranges ( Fu and Wang, 2011 ; Hocaoglu et al, 2021 ). However, filtration-based systems are quite expensive, and they are susceptible to membrane fouling, resulting in a decrease in permeate flux.…”

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.

“…Wastewater generated from various sources like agricultural [ 1 , 2 ], industrial [ 3 , 4 , 5 , 6 ], commercial [ 7 , 8 , 9 ], the institution [ 6 , 10 ], and domestic [ 11 , 12 ] with different contents of pollutants that affect the natural condition of the environment [ 6 , 11 ]. Rendering to [ 6 , 13 ] hospital is an institution that needs a huge quantity of water and abstemiously releases wastewater to an environment that contains toxic pollutants such as metal oxides, hazardous liquid waste from various units, radioactive waste, bacteria, viruses, blood, fluids, different concentration of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) that affects environments in different aspects [ 14 , 15 ]. A number of technologies are functional to minimize effects of hospital wastewater generated such as ion-exchange [ 16 ], adsorption [ 6 , 17 , 18 , 19 ], coagulation-flocculation [ 6 , 18 ], electro-dialysis [ 20 ], chemical oxidation [ 6 , 21 ], reverse osmosis [ 19 , 22 , 23 ], filtration [ 24 ], ultrafiltration [ 23 , 25 , 26 , 27 ] and activated sludge [ 21 , 28 , 29 , 30 , 31 ], etc., Based on the fundamentals of wastewater treatment techniques, their advantages and disadvantages are summarized in Table 1 .…”

Hospital wastewater contains heavy metals that threaten environmental and human health through bioaccumulation and biomagnification. Each heavy metal contributes a different impact on human health and the environment. Monitoring the heavy metals in wastewater is essential to prevent those severe impacts. However, it is still rare for a study to assess heavy metals obtained from the discharge of hospital wastewater in Indonesia. Therefore, this study investigated 14 parameters of heavy metals in hospital wastewater. We tested wastewater quality from September 2021 to February 2022, with SNI 6989-59-2008 sampling methods with 14 parameters. Results show that over 14 parameters are still below the threshold value and other previous studies. It might be because the biological treatment used in the hospital wastewater treatment plant (HWWTP) reduces these micropollutants efficiently. The fluidized bed biofilm reactor (FBBR) system is an aerobic process with microorganisms attached to the bio-green. This technique is to form suspensions of solid particles in sparse media with gas streams for chemical or physical processes. The sewage discharge reveals the occurrence of heavy metals in hospital wastewater, even though it does not reveal a high concentration due to the effectiveness of the FBBR system in HWWTP.
