CFD in the water and wastewater industry: aeration tank
This multiphase simulation uses a Euler-Euler approach to analyse the gas-liquid system. Thanks to this kind of CFD simulation, not only the velocity and the pressure field can be analysed but also the total air hold-up and standard oxygen transfer rate can be calculated.
CFD in water and wastewater treatment: rectangular clarifier
This animation shows a transient multiphase simulation of a rectangular clarifier. Clear water is collected with a system of perforated piping system at 0.5 m of submergence. The sludge is recollected at the bottom-left part of the basin with two suction pipes.
