CFD software for Water Treatment?
 

Hi, I am interested in using CFD software for the water treatment field and I am not sure which should I use: Fluent, CFX or Star-CD? My purpose is to do CFD simulations for aeration tanks, sand filters and RBM (membrane bio-reactor), so it is important that simulates correctly multiphase and discrete particles in a fluid (water).

Has anyone had any experiences in this field? Thanks!!!
