This semester, I am continuing research as part of the Sedimentation Tank Hydraulics Team. I will be conducting experiments and collecting quantitative data to evaluate the design requirements for floc blanket formation and maintenance. The goals for the semester are:
- Test a hypothesis that describes the conditions required for floc blanket formation. The hypothesis is that the hydrodynamic pressure of the jet must exceed the hydrostatic pressure of the debris flow in order for flocs to be resuspended.
- Determine the maximum upflow velocity in the sedimentation tank that will reliably give a performance of 2-3 NTU.
- Evaluate the effect of high jet velocities on floc breakup and effluent performance.
- Develop an understanding of how floc consolidation works, and determine design guidelines for the floc hopper.
