Abstract
The operation of a continuous-flow sludge blanket clarifier is simulated by use of the continuity equations. The result of including an orthokinetic flocculation term due to the small-scale turbulence generated by the falling particles is examined and compared with the results obtained when only a “catch-up” flocculation mechanism is included. Turbulence flocculation permits the agglomeration of fines and results in an increase in clarifier efficiency. The effects of hydraulic loading and influent solids volume fraction are studied.Keywords
