The well known models of ideal\/real\r\nmixing, ideal displacement (plug flow) and (one-dimensional axial)\r\ndispersion model were combined in order to identify the structure\r\nthat gives the best fitting of the experimental data for each equipment\r\nof the pilot plant. RTD experimental results have shown that pilot\r\nplant hydrodynamics can be quite well approximated by a\r\ncombination of simple mathematical models, structure which is\r\nsuitable for engineering applications. Validated hydrodynamic\r\nmodels will be further used in the evaluation and selection of the\r\nmost suitable coagulation-flocculation reagents, optimum operating\r\nconditions (injection point, reaction times, etc.), in order to improve\r\nthe quality of the drinking water.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 52, 2011"}
