Technical Article: Energy Saving Potential for Mixing of Horizontal Flow Systems

13.02.2013 -

In a study of a Danish wastewater treatment plant Computational Fluid Dynamics simulations shows a potential of energy savings of more than 50%. For submersible mixing in an activated sludge tank this can be realized by changing from medium speed small diameter propeller mixers to slow speed large diameter propeller flowmakers without altering the flow field in the tank.
