Chemical Dose Controller Meeting Minutes
Spring 2009 Minutes
2/28/09
Working Group: Nonlinear CD
Nadia
Julia
Accomplishments
- Met with Monroe to discuss Design
- Worked on MathCAD Design file
Metrics
- for 6000 L/min plant flow, the maximum flow through the CD will be 2.5 L/min
- The diameter of the tubing between the flow controller and the pressure break T is 0.75 in
- For up to 10000L/min plant flow, float valves PT75SS or
PT100SS will give minimal headlosses
Outcomes
- Need to design system based on a range of plant flow rates
- Need to add force balance of CD vs. float to the mathCAD file
Issues
- Need to design flow control module to incorporate contain large float valve into designdevice

Linear CDC
Accomplishments
...
- We set up the existing chemical doser with the 3/8" tubing.
- Met with Monroe to set up and outline for the paper
- Worked on creating a robust float sizing algorithm
Metrics
- The 3/8" tube maintained free fall
Outcomes
- Need to order 1/4" T and test to see if it maintains free fall.
- Need to document tests of different tubing sizes.
- Determined the scope of the paper
- Established proper nomenclature for the Chemical Dose Controller
- Determined previous data may be compromised
- We will meet on Sunday to work on Mathcad
Issues
- Need to specify scope and data inclusion for paper
- Need to determine the part name so that we may order the T
Metrics
- Quantitative and qualitative results from accomplishments and outcomes.
- Potential metrics for unresolved issues.
Outcomes
- A summary of resolutions based on what was accomplished.
- New directions and ideas that result from these resolutions.
Issues
- Difficult and unresolved issues
- Plans for action
