3D-CFD simulations will be used to improve an ozonation reactor and a dissolved air flotation reactor in wastewater treatment plants. The goal is to reduce investment and operational costs, improve wastewater quality by removing micropollutants, and optimize purification efficiency.
Start date: 01/06/2021
Duration in months: 18
Problem Description
The use-case concerns the improvement of an ozonation reactor to optimize wastewater purification
Goals
New services
Challenges
The degradation efficiency of micropollutants depends on the flow pattern, the transition from the gaseous ozone to the liquid phase and the even distribution of the ozone over the total inflow. These aspects need to be modelled appropriately.
Innovation results
The experiment resulted in higher efficiency of the ozone reactor geometry, gassing plate, and system mechanism to increase wastewater purification.
Business impact
Reduce upfront and ongoing costs of up to 20%
