Spring 2011 Mid-Semester Contributions

As the Sedimentation Tank Hydraulics Team is working on a new project, much of the initial research so far has been in was design. I worked with Yiwen to design the tube flocculator so that the energy dissipation rate is approximately but does not exceed 10 mW/kg, the scouring velocity is sufficient to prevent settling out, the flow is laminar, and the residence time is such that flocs of reasonable size are produced. Much of the design work has also included contributing to a Research Rationale with figures drawn to scale, and working together to create a materials list for our new set-up.flocculator to produce reasonably size flocs for our sedimentation tank. The flocculator was designed for an energy dissipation rate to encourage floc formation, for a sufficient scouring velocity and laminar flow, and for a residence time to produce flocs of a predicted size. Following, considerations about diffuser height and spacing were examined so as to design a manifold with no dead zones along the length of the sedimentation tank.

Subsequent experimental contributions include working the team to determine the minimum angle of repose needed to form a floc blanket.
