Combined use of LS-PIV and CFD for the characterization of turbulent flow in the contact chamber of ‘COSTA AZUL’ wastewater treatment plant, Carlos Paz

The Costa Azul wastewater treatment plant is situated in Carlos Paz city (Córdoba, Argentina). The treated water is discharged to the San Roque reservoir, which is the source of water for the city of Córdoba and surrounding towns. Consequently, it is of great importance to evaluate the potential imp...
