From the results of tracer test for the existing chlorine contactor in Y water treatment plant, T10 and T10/T were calculated as 130 min and 0.16, respectively. Therefore it required the modification schemes for improving hydraulic efficiency, surrogated by T10 and T10/T, and disinfection performance. In this study, in order to reduce dead zone within contactor, to install porous baffles in the near of each corner was suggested and verified using transient CFD(Computational Fluid Dynamics) simulation technique and tracer tests on dynamic condition. From the results of simulation and tracer tests, it was revealed that porous baffles installed have been effective to reduce dead zone within contactor, and increase plug flow fraction. |
