Plate Settler Spacing Meeting Minutes
Spring 2009 Minutes
2.27.09
Working Group: 1
(this is all last weeks stuff. update for this week)
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.
