The modeling approach used was a three dimensional, multi-phase simulations with solids transport and removal included, and reflected the state of the art in clarifier modeling. Special attention was paid to the inlet baffles and outlet weirs in the model setup. The techniques used within and the general results of the model will be presented. The results include vector plots, sludge blanket levels, effluent solids concentrations and detailed residence time distribution (RTD) curves.", pages = "6695-6706", url = "http://www.ingentaconnect.com/content/wef/wefproc/2006/00002006/00000005/art00030", doi = "doi:10.2175/193864706783761310" }
