| Abstract: | Radiation processing of municipal sewage and sludge has been considered not only for disinfection but also for solids and organic matter removal in Brazil. The improvement of irradiated systems were demonstrated by the elimination of indicator bacteria and by the reduction on the total bacteria count, on the chemical and biochemical oxygen demand from raw sewage and biologically treated effluents. The selected doses of radiation to be applied to sewage and sewage sludge are in the range of 3.0 to 4.0 kGy to sewage and 4.0 to 6.0 kGy to sewage sludge. |
