Description

This paper presents some results obtained by using electron beam accelerator applied to sewage and sludge as a disinfectant technology. the samples were collected at two different wastewater treatment stations from Sao Paulo. The disinfection efficiency was observed by the enumeration of total and fecal coliforms and total aerobic bacteria, which were selected for this study once they are universal indicators for biological contamination of water. Doses to be applied were selected in the range of 3.0 to 4.0 kGy for sewage, and 5.0 to 15.0 kGy for sludge. The irradiation induced other benefits than disinfection. The chemical and biochemical removal demand was slightly reduced as well as the total solids residues. (author). 4 refs., 4 figs., 1 tab
