This article presents SimOx, the new simulator being currently developed by Anjou Recherche / ENSCR for oxidation steps in potable water treatment works. Whereas designing this new prediction engine was originally motivated by difficulties encountered when simulating a plant under on-site conditions, an increasingly stringent legal context and the emergence of micropolluants of concern clearly confirmed the need for a performing and innovative tool. The experience gained with the development of previous simulators is of advantage and opens interesting possibilities, in particular calculation capabilities upon which SimOx partly bases. Nevertheless, given the very characteristics of the new simulator SimOx (capacity to deal with sparse on-site data under changing water matrixes and hydrodynamic conditions), special modelling and calculation procedures are being implemented.
