The aim of the project is to design such parameters of sludge sanitation processes that will safely ensure the removal of ARB and ARG so that the sludge can be used as an agricultural fertilizer.
The project will test the effectiveness of available sewage sludge sanitation technologies in terms of their ability to remove antibiotic resistance and SARS-CoV-2 contamination. Process conditions leading to the removal of these pollutants will be sought for all technologies. Sludges from thermophilic and mesophilic anaerobic stabilization, sludges after aerobic stabilization, sludges from grease separators, and wastes exported to the WWTP will be selected as tested sludges.
In addition, the presence of ARG and SARS-CoV-2 virus in the Prague sewer network will be monitored in localities selected with regard to the type of settlement and potential sources of infection.
