“…So, the unmatched results may be a reflection of underestimation over circulation of NoV GII.17. Sewage analysis is an important molecular surveillance tool to understand the genetic diversity of enteric viruses in a human population (La Rosa et al, 2017;Mabasa et al, 2015;Montazeri et al, 2015;Prado et al, 2018). WHO used sewage to monitor poliovirus circulation in communities worldwide as a part of the Global Polio Eradication Initiative with combining clinical surveillance (Benschop et al, 2005).…”

“…In other words, raw sewage may act as a valuable source to characterize the prevalence of enteric viruses in a human population. Accordingly, several studies have used raw sewage for molecular epidemiology as a source of information on the viruses circulation through the fecal-oral route (Fumian et al, 2019;La Rosa et al, 2017;Montazeri et al, 2015;Nenonen et al, 2008;Prado et al, 2018).…”

Norovirus (NoV) prevalence was investigated in 100 sewage samples collected from 35 individual septic tanks around the drainage basin of Jaran Bay, Korea in January, May, and July of 2017. Genotypes and diversity of NoV strains detected in sewage samples were also assessed using the conventional RT-PCR and phylogenetic analysis. NoV GI or GII were detected in 22 (22.0%) and 24 (24.0%) samples, respectively. Thirteen genotypes were identified with three dominant genotypes (GI.9, GII.5 and GII.17) and GII.17 showed relatively higher prevalence during the survey period. GII.17 strains were clustered into recombinant type variant or NoV GII.17 Kawasaki variant. NoV GII.17 strains were considered emergent epidemic variants with widespread circulation. NoV surveillance strategy should include both environmental (sewage) and clinical data to reveal minor NoV genotypes likely cause of asymptomatic or underreported infections in the local population.

“…Activated carbon was selected because it is a material with a high degree of porosity and a high internal surface (Krahnstöver & Wintgens, 2018). The angular shape of anthracite is ideal retain the solids (Prado et al., 2019), and the zeolite material was chosen due to the fact that suspended or colloidal particles can be retained in its pores (Hosseini Hashemi et al., 2019).…”

The biodegradation of domestic wastewater contaminants has been carried out using microorganisms immobilized in sodium alginate gel (Alg‐Na). A fixed bed reactor with immobilized microorganisms was used for the treatment of domestic wastewater. A wastewater pretreatment was carried out to remove the larger particulate matter, which consisted of a reactor packed with different materials (anthracite, zeolite, and activated carbon). Later, a second reactor packed with balls with immobilized microorganisms was used to eliminate organic matter and nutrients. 2.5% w/v of Alg‐Na was used as a support to immobilize the microorganisms. According to the results, a total phosphorus (TP) and chemical oxygen demand (COD) removal of 94.26% and 78.25% was obtained, respectively. In addition, the degradation rate for both organic matter and phosphorous was studied by using the kinetic model for fix bed reactor. © 2020 Water Environment Federation Practitioner points Phosphorous and organic matter removal by adsorption and immobilized microorganisms. High removal efficiency of phosphorous and organic matter was found. An innovative wastewater treatment alternative is proposed. Kinetic model for fixed bed reactor is also proposed for scaling‐up purposes.

“…Viral removal between 2 and 3 log10 has been reported for different types of viruses during membrane bioreactor (MBR) treatment (Prado et al, 2019;Miura et al, 2018;Purnell et al, 2016). Other studies have reported Log removal of viral particles greater than 4 (Chaudhry et al, 2015;Kuo et al, 2010).…”

The last 17 years have seen three major outbreaks caused by coronaviruses, with the latest outbreak, COVID-19, declared a pandemic by the World Health Organization. The frequency of these outbreaks, their mortality and associated disruption to normal life calls for concerted efforts to understand their occurrence and fate in different environments. There is an increased interest in the occurrence of coronaviruses in wastewater from the perspective of wastewater-based epidemiology. However, there is no comprehensive review of the knowledge on coronavirus occurrence, fate and potential transmission in wastewater.This paper, provides a review of the literature on the occurrence of coronaviruses in wastewater treatment processes. We discuss the presence of viral RNA in feces as a result of diarrhoea caused by gastrointestinal infections. We also reviewed the literature on the presence, survival and potential removal of coronaviruses in common wastewater treatment processes. The detection of infectious viral particles in feces of patients raises questions on the potential risks of infection for people exposed to untreated sewage/wastewater. We, therefore, highlighted the potential risk of infection with coronaviruses for workers in wastewater treatment plants and the public that may be exposed through faulty plumbing or burst sewer networks.The mortalities and morbidities associated with the current COVID-19 pandemic warrants a much more focused research on the role of environments, such as wastewater and surface water, in disease transmission. The current wealth of knowledge on coronaviruses in wastewater based on the reviewed literature is scant and therefore calls for further studies.
