| Abstract | The water availability is becoming limiting in several European Countries. Agriculture represents the main water user therefore the reuse of wastewater in agriculture could provide a valuable increase in freshwater resources for other needs. A plan for an effective wastewater reuse should be based on compact delocalized treatment plants located in the same area where water has to be reused. Sequencing Batch Biofilter Granular Reactor (SBBGR) technology could deal with this requirement. This system is characterized by excellent treatment performances in removing organic pollutants, suspended solids and nitrogen. However these parameter couldn't ensure a safely wastewater reuse because water could still contain microbial pathogens. The aim of this study was to evaluate the effectiveness of raw domestic sewage treatment by SBBGR for agricultural reuse. Particular attention was dedicated to microbiological quality of water monitoring a wide group of microbial indicators (total coliforms, E. coli, Salmonella, C. perfringens, Somatic coliphages, G. lamblia and C. parvum). The possibility of SBBGR enhancement with physical and chemical disinfection processes was also evaluated. |

L agriculture representant le principal utilisateur, la reutilisation des eaux usees dans l agriculture pourrait fournir des ressources supplementaires en eau douce pour d autres besoins. Un plan pour une reutilisation efficace des eaux usees devrait se baser sur des usines de traitement compacts et delocalisees, situees dans la zone ou l eau doit etre reutilisee. La technologie de Sequencing Batch Biofilter Granular Reactor SBBGR pourrait faire face a cette exigence. Ce systeme se caracterise par d excellentes performances pour l elimination des polluants organiques, des solides en suspension et de l azote. Cependant cela pourrait ne pas etre suffisant pour assurer une reutilisation des eaux usees en toute securite, parce que l eau pourrait encore contenir des agents pathogenes microbiens. Le but de cette etude est d evaluer l efficacite du traitement des eaux usees domestiques brutes par SBBGR pour la reutilisation agricole. Une attention particuliere a ete consacree a la qualite microbiologique de l eau par le suivi d un large groupe de micro organismes indicateurs. La possibilite d ameliorer les performances du SBBGR par des processus de desinfection physiques et chimiques a egalement ete evaluee.
