Spring 2009 Minutes

2.27.09

Working Group: 1

(this is all last weeks stuff. update for this week)

Accomplishments
  • Added floc blanket control valve and extended outlet into column to control height.
  • Extended bubble trap tube.
  • Rotated sedimentation tubes 90 degrees.
  • Completed revision of semester goals
  • Met with Monroe to improve system design and dicuss experiments.
Metrics
  • Kellie updated the mathcad file to include calculations of flow rates based on our Vc range
Outcomes
  • Need to update process control to include incrementation and a new state to change flow rates
  • Need to order new tubes with larger diameters
Issues
  • Process Controller
  • Need to make a schedule to moniter the system
  • Camera?
Accomplishments
  • Began automating the system using the increment method in Process controller
  • Recoded the process controller program for floc blanket and effluent flow rate variation
  • Ran the system to test floc blanket formation
  • Added an elbow
  • Sucessfully floc blanket height using process controller
Metrics
  • None this week
Outcomes
  • We are continuing to debug our process controller method to automate the varying of flow rates
  • In the process of ordering a web cam to monitor floc blanket height. This will help us deterimine the time it takes to form a floc blanket.
Issues
  • When increment function restarts instead of starting at the minimum flowrate it starts at the maximum flowrate.
  • We need to do some test runs of the system to determine the necessary duration of each process controller state.

Any Overall Team Comments:

  • Most of the week was spent working with process controller. Next week we look forward to collecting data.
