Goals for Spring 2009

Subteam Leader

  • Sarah Long, Colette Kopon

Other Team Members

  • Kellie Kress

Goals

  • Create protocol for running experiments (i.e. determine control of parameters such as tube length, Vc, upflow velocity, etc.)
    • Colette and Sarah will create this form by February 5, 2009
  • Setup apparatus to begin completing experiments and calibrate floc blanket control weir
    • All group members are responsible for completing this by February 11, 2009
  • Complete experiments that vary tube diameter
    • All group members are responsible for completing this by February 27, 2009
  • Complete experiments that vary flow rates
    • All group members are responsible for completing this by March 20, 2009
  • Design and complete experiment to vary tube length
    • All group members are responsible for completing this by April 17, 2009

      Experiment I: The first series of experiments will evaluate the effect of tube settler diameter on effluent turbidity. Three different tube diameters will be tested with the same up flow velocity 100. The system will be run continuously for the duration of the experiment: floc blanket will be maintained during the changing of the tube settlers. Tube settlers will not be inserted into the distillation column prior to the establishment of the floc blanket so that there is no floc build-up on the tube settlers prior to data collection. Each diameter will be tested for at least twenty-four hours.

Experiment II: The second series of experiments will evaluate the effect of flow rate on effluent turbidity. Three different flow rates will be run through each of the three diameters of tube settlers. Again, the system will be run continuously for the duration of the experiment to maintain continuity within the results. A new state in process control will automate the change of the flow rates. Each flow rate/diameter combination will be tested for at least twenty-four hours.

Experiment III: The third series of experiments will evaluate the effect of geometry (length and diameter) on the effluent turbidity. L/b, Vc, L, and Q will be determined after analyzing results from experiments I and II.

Deliverables

  • Generate a form that will determine sedimentation performance and design based on various system parameters.
    • All group members are responsible for competing this by the end of the term
  • No labels
