Effluent sewer systems are a much less common sewage disposal method than gravity sewer systems that use gravity, as well as pumping where needed, to send raw sewage and other wastewater straight from consumers to a sewage treatment plant. There are two main types of gravity sewers, sanitary and combined. Sanitary sewers only treat the ...

The global 'resistome' based on sewage-based monitoring [45] Gene-sharing network between bacterial genera [45] In 2022, genomic epidemiologists reported results from a global survey of antimicrobial resistance (AMR) via genomic wastewater-based epidemiology, finding large regional variations, providing maps, and suggesting resistance genes are ...
But wastewater surveillance — the testing of sewage for signs of pathogens such as SARS-CoV-2, poliovirus and mpox virus — has yet to be employed in the tracking of H5N1 bird flu virus.
Newsy learned New York State, for example, suspended its sewage surveillance pilot after a month in part because of an equipment shortage. As a result, testing stopped in four places including ...
The sewage treatment plant includes primary-secondary treatment and the following advanced wastewater treatment processes: chemical clarification, two-stage recarbonation with intermediate settling, multimedia filtration, granular activated carbon adsorption, chlorination for disinfection and dechlorination.
