A High Rate Sedimentation (HRS) process that uses upward flow and less area than traditional tanks was investigated. The objective was to analyze parameters affecting HRS tank performance including velocity, density of the floc blanket and location of plate settlers in a laboratory scale HRS tank. Different velocities were set during the experiment, and the resulting performance of the floc blanket was evaluated through continuous turbidity measurements. Results demonstrated that the lab-scale tank allows the creation of a floc blanket and is a versatile design with constraints of visibility and accessibility. In addition, performance of the sedimentation tank improves at lower up flow velocities; however, the study suggests that plate settlers at the top of the tank stabilized the floc blanket at higher velocities, as a consequence of denser floc blankets created by the plates. 2019 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43065097002 https://www.redalyc.org/journal/430/43065097002/ https://www.redalyc.org/journal/430/43065097002/html/ https://www.redalyc.org/journal/430/43065097002/43065097002.epub https://www.redalyc.org/journal/430/43065097002/movil 10.17533/udea.redin.n90a02 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.90 |
