Wpływ konstrukcji komór kontaktowych na skuteczność ozonowania wody

The objective of the study was to relate the hydrodynamic performance of the multistage ozone contactor to some of the major geometrical parameters (e.g., the number and type of baffles), and the efficiency of oxidation and disinfection to the location of the diffusers. Experiments were carried out with a model of a 0.259 m[3] volume four-stage ozone contactor. The application of single or double baffles allowed the contactor to act as a one-, two- or four-compartment model. When use was made of double baffles, the hydraulic behaviour of the contactor shifted towards that of a plug-flow reactor. Total and partial aeration was tested in the four-stage ozone contactor. Total gas flow was either sent to the first compartment or was distributed into all or some of the diffusion chambers. The study evidenced a strong influence of the investigated parameters not only on the hydrodynamics of the contactor, but also on the efficiency of ozone transfer and effective of oxidation/disinfection.
