Fall 2008 Goals

Resetting Tube Flocculator (9/4/08)

...

Start up tube flocculator with vacuum pump (9/1819/08)

• all Repair leaks in the pilot plant system must be fixed so system so that the plant can run in order to run tube flocculator.

Write Midterm Report (10/21/08)

Compare results from the uniform and non-uniform baffle configuration results from the flocculation tank (11/12/08)

• Baffles had to be reconifgured to the correct arrangement.
• Correct spacing between the baffles had to be determined.

Create floc profile for tube flocculator (911/2620/08)

• The turbidity of the flocculator will be measured at various points along the flocculator.
• A profile similar to the one measured for the tapered flocculator will be made. Gtheta for maximum floc size will be determined.

...

Measure settling velocity of flocs in the tube flocculator with and without upflow (11/5flocculator with FRETA (12/1/08)

• Construct settling columns. One will have an upflow velocity that is equivalent to the tanks upflow velocity. One will have still water.
• The settling columns will be used to determine how floc size and density affects the critical terminal velocity of the flocs.

Tapered Flocculation

• If time allows and alternative parameters for G and Gtheta are determined by the tube flocculator experiments, the Pilot Plant Team will investigate new baffle configurations for optimized flocculation Compare laboratory results with raw water readings from the Pilot Plant using FRETA.

Prepare final presentation and report (12/12/08)
