Utilization of the interactive LED software for modeling a drinking water treatment plant
Résumé
Building models which take into account all the collected data of a process represent a difficult problem due to the following facts: great number of data and observations, outliers, inconsistent data, missing data, correlation between data, redundancy of some variables ... The following example illustrate this matter. The first step of a drib king water treatment plant at Morsang sure Seine, located upstream from paris, is presented here. This plant (150 000 m3/day), which treats water from the Seine; consists of two different lines. In the first one, prechlorination with addition of activated carbon powder, floculing)settling and sand filtration, followed by ozonation and chlore disinfection are carried out. In the second line, no carbon powder is used during prechlorination and after ozonation, a filtration step on granular activated carbon is added. The first part of this work dealt with data handling and presents the building of the models for this plant; the second part is devoted to the presentation of the software LED which was used for modeling purposes.
