Disinfection of faecal indicator organisms by iron electrocoagulation for reuse of sewage water

Due to the quick growth in human population and subsequently a high rate of urbanization, fresh water sources are under pressure. Estimated 1.8 billion people drink water from potentially sewage-contaminated sources and also the presence of antibiotic resistant bacteria in sewage has made the improper treatment of wastewater effluent an emerging...

Removal of bacterial and viral indicator organisms in full-scale aerobic granular sludge and conventional activated sludge systems

The aim of this study was to evaluate the effectiveness of the novel aerobic granular sludge (AGS) wastewater treatment technology in removing faecal indicator organisms (FIOs) compared to the conventional activated sludge (CAS) treatment system. The work was carried out at two full-scale wastewater treatment plants (WWTP) in the Netherlands,...

Source tracking of Enterococcus moraviensis and E. haemoperoxidus

Enterococciwere detected occasionally in 100 L samples ofwater abstracted froma shallowaquifer in a natural dune infiltration area for drinking water production. Enterococcus moraviensis was the species most frequently identified in these samples. Because there are no existing reports of faecal sources of E. moraviensis and the closely...
