Using CFD to Optimize Unit Treatment Processes in a Waste Water Treatment Works
« All Publications

Computational Fluid Dynamics can be used to generate a computational model of a treatment unit in order to calculate the process performance.

The advantage of a computational model developed during the design stage is that optimization can be undertaken by assessing either geometric changes or process conditions. In its most basic form, the Activated Sludge Process (ASP) comprises a reactor, in to which waste water continually flows, followed by a settling tank to remove the biomass. Some of the biomass is surplus and removed from the system and some is returned back to the reactor. A waste water activated sludge plant includes several operational stages where the hydraulic behavior is key to achieving optimum efficiency. This includes distribution chambers, anoxic zones and Final Settlement Tanks (FSTs).
