“…Substantial load of SARS-CoV-2 arriving at WWTPs should raise concerns for its aerosolization and ultimate implications in public health. Due to the significant concentrations of SARS-CoV-2 RNA in wastewater, WWTPs are gaining attention for early tracking and removal of this virus [29]. The viral loads can be decreased in WWTPs by wastewater disinfection and filtration [3,30].…”

The existence of SARS-CoV-2, the etiologic agent of coronavirus disease 2019 (COVID-19), in wastewater raises the opportunity of tracking wastewater for epidemiological monitoring of this disease. However, the existence of this virus in wastewater has raised health concerns regarding the fecal–oral transmission of COVID-19. This short review is intended to highlight the potential implications of aerosolized wastewater in transmitting this virus. As aerosolized SARS-CoV-2 could offer a more direct respiratory pathway for human exposure, the transmission of this virus remains a significant possibility in the prominent wastewater-associated bioaerosols formed during toilet flushing, wastewater treatment, and sprinkler irrigation. Implementing wastewater disinfection, exercising precautions, and raising public awareness would be essential. Additional research is needed to evaluate the survival, fate, and dissemination of SARS-CoV-2 in wastewater and the environment and rapid characterization of aerosols and their risk assessment.

“…Thus, MBR has the ability to retain microbial community to degrade organics, produce high solid and pathogen-free effluents as well as the capacity to recover the energy potential of soluble organic matter [51,61]. MBR technology has demonstrated to be a more effective system in removing pathological micro-organisms, including SARS-COV-2 [63]. Researchers have determined the diameter of SARS-COV-2 to range between 60 and 140 nm [62][63][64], where viral load in WWTP has been found to range between 2 and 3.10 3 copies/mL, depending on the level of the epidemic [64,65].…”

“…Therefore, its efficiency in removing the viral load is expected to be higher. This technology can also shorten the reaction time (approximately 1.5 min, 2.5 to 5% of traditional wastewater treatment process), viably save disinfectant consumption (chlorine addition can diminish to 1.0 mg/L), and achieve a decent impact of inactivation of micro-organism [63,65]. Higher disinfection viability is accomplished in MBR effluents at a lower dose of disinfectant with fewer disinfection by-products (DBPs) [66].…”

“…Higher disinfection viability is accomplished in MBR effluents at a lower dose of disinfectant with fewer disinfection by-products (DBPs) [66]. In the past, MBR was considered inappropriate in WWTP due to its high operating cost; however, decreasing cost and stringent standards are making the use of MBR systems more economically viable [61,63]. For instance, when the limit of MBR plants is increased from 20 to 1000 m 3 /d, their operating cost is projected to reduce sharply [67].…”

The coronavirus (COVID-19) pandemic is currently posing a significant threat to the world’s public health and social-economic growth. Despite the rigorous international lockdown and quarantine efforts, the rate of COVID-19 infectious cases remains exceptionally high. Notwithstanding, the end route of COVID-19, together with emerging contaminants’ (antibiotics, pharmaceuticals, nanoplastics, pesticide, etc.) occurrence in wastewater treatment plants (WWTPs), poses a great challenge in wastewater settings. Therefore, this paper seeks to review an inter-disciplinary and technological approach as a roadmap for the water and wastewater settings to help fight COVID-19 and future waves of pandemics. This study explored wastewater–based epidemiology (WBE) potential for detecting SARS-CoV-2 and its metabolites in wastewater settings. Furthermore, the prospects of integrating innovative and robust technologies such as magnetic nanotechnology, advanced oxidation process, biosensors, and membrane bioreactors into the WWTPs to augment the risk of COVID-19’s environmental impacts and improve water quality are discussed. In terms of the diagnostics of COVID-19, potential biosensors such as sample–answer chip-, paper- and nanomaterials-based biosensors are highlighted. In conclusion, sewage treatment systems, together with magnetic biosensor diagnostics and WBE, could be a possible way to keep a surveillance on the outbreak of COVID-19 in communities around the globe, thereby identifying hotspots and curbing the diagnostic costs of testing. Photocatalysis prospects are high to inactivate coronavirus, and therefore a focus on safe nanotechnology and bioengineering should be encouraged.

Presently, the coronavirus (COVID‐19) epidemic presents a major threat to global communal fitness also socio‐financial development. Ignoring worldwide isolation as well as shutdown attempts, the occurrence of COVID‐19 infected patients continues to be extremely large. Nonetheless, COVID‐19's final course, combined with the prevalence of emerging contaminants (antibiotics, pharmaceuticals, nanoplastics, pesticides, and so forth) in wastewater treatment plants (WWTPs), presents a major problem in wastewater situations. The research, therefore, intends near examine an interdisciplinary as well as technical greet to succor COVID‐19 with subsequent COVID cycles of an epidemic as a framework for wastewater treatment settings. This research investigated the potential for wastewater‐based epidemiology to detect SARS‐CoV‐2 also the enzymes happening in wastewater conditions. In addition, a chance for the incorporation into the WWTPs of emerging and robust technologies such as mesmeric nanobiotechnology, electrochemical oxidation, microscopy, and membrane processes to enhance the overall likelihood of environmental consequences of COVID‐19 also strengthen such quality of water is resolved.
