Water Purification Reactor
Application ID: 14049
Water purification for turning natural water into drinking water is a process constituted of several steps. At least one step must be a disinfectant step. One way to achieve efficient disinfection in an environmentally friendly way is to use ozone. A typical ozone purification reactor is about 40 m long and resembles a maze with partial walls or baffles that divide the space into room-sized compartments. When water flows through the reactor turbulent flow is created along its winding path around the baffles towards the exit pipe. The turbulence mixes the water with ozone gas that enters through diffusers just long enough to inactivate micro-pollutants. When the water leaves the reactor, the remaining purification steps filter off or otherwise remove the reacted pollutants.
In analyzing an ozone purification reactor, the first step is to get an overview of the turbulent flow field. The results from the turbulent-flow simulation can then be used for further analyses of residence time and chemical species transport and reactions by adding more physics to the model. The current model solves for turbulent flow in a water treatment reactor using the Turbulent Flow, k-epsilon interface.
