Fall 2012

This semester I'm a member of Tube Floc team. The past members of this team have already tested how hydraulic retention time, coagulant dose, water solution properties influence the removal efficiency. My task for this semester is to break large flocs based on calculation of energy dissipation rate to see if this is helpful for improving flocculation performance. This task can be divided into 2 steps: first, I need to reproduce Dr. Karen Swetland's past experiments as a baseline for future experiments; second, in this baseline,  the residual turbidity will be measured under the same experimental conditions but with breakup of large flocs at regular intervals.
