The well known models of idealreal mixing, ideal displacement (plug flow) and (onedimensional axial) dispersion model were combined in order to identify the structure that gives the best fitting of the experimental data for each equipment of the pilot plant. RTD experimental results have shown that pilot plant hydrodynamics can be quite well approximated by a combination of simple mathematical models, structure which is suitable for engineering applications. Validated hydrodynamic models will be further used in the evaluation and selection of the most suitable coagulationflocculation reagents, optimum operating conditions (injection point, reaction times, etc.), in order to improve the quality of the drinking water.</abstract> <index>Open Science Index 52, 2011</index> </article>
