Fine Tuning for Water Purification

Amsterdam Water Supply (AWS) of the Netherlands produces some of the cleanest drinking water in the world using an environmentally benign ozone disinfection approach. To clean up the 100 million cubic meters per year they handle requires giant turbulent disinfection reactors. COMSOL Multiphysics simulations help AWS researchers Dr. Jan Hofman and colleagues fine tune what happens inside these big rigs.

In the header assembly for the turbulent ozone reactors, filtered water passes through large pipes and empties into a long conduit or header roughly 1m in diameter. The header mixes the filtered water and feeds it into the turbulent ozone reactors through relatively small pipes or "streets".
