Abstract:The present work studies the influence of the design of active sludge inlet structure (influent well) and treated water outlet structure (position and shape of effluent weir), in the performance of a secondary clarifier for waste water treatment. The study has been carried out through CFD simulations with the openFoam software, in which different combinations of input and output structures have been analysed. The obtained results show a great influence of these structures in the velocity fields and the solids distribution inside the clarifier. These structures have shown to be a key factor regarding clarifier performance, both in transport and extraction of sludge, as well as in suspended solids content in the effluent. Results have shown a great dependency of flow fields on sludge density and rheologic properties. Secondary
