Summary

Disinfection is the destruction of viable, potentially infectious pathogens. Disinfection can be achieved through several operational processes at wastewater treatment systems. Thermophilic processes such as aerobic and anaerobic digesters and sludge composting reduce the number of viable pathogens. Mesophilic aerobic and anaerobic digesters also destroy viable pathogens.
