Plate Settler Spacing QUIZ!!! -Kellie
General Questions:
1. What does the PSS team do? What are the PSS team's goals for this semester?
The PSS team is trying to find the optimal spacing between plate settlers. Currently, the research that is being performed uses plate settler tubes to see how small the tubes can be without clogging. I think for this semester, we're going to try to hold the upflow velocity in the plate settler tubes constant while changing the diameter of the tubes.
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
2. List one personal goal that you hope to achieve on the PSS team this semester.
I hope to become more familiar with the research process. Last semester, I had a hard time on the pilot plant because I have never done independent research before, and so this semester I'm looking forward to helping Sarah and Colette with their research so that I'll be equipped with the skills to do experiments in the future without too much assistance.
3. Where do go to find last semester data?
Home > Research > Sedimentation Prototype > Plate Settler Spacing > Effects of the inner diameter of tube settlers on sedimentation
4. What do you do if you have a question?
First ask Sarah or Colette, if I still don't really understand, look at the wiki for further information or talk to Monroe or Nicole.
5. Who is the PSS team leader? What is his or her email address?
Sarah Elizabeth Long sealong212@gmail.com
Colette Kopon ckopon@gmail.com
Technical Questions:
1. When does sedimentation occur in the water purification process?
Sedimentation occurs after flocculation and before the chlorine dosing.
2. What is one purpose of flocculation?
Flocculation makes all the dirt and clay particles stick together so that they are easier to settle out during sedimentation.
3. What is critical velocity?
The critical velocity is the slowest velocity of a particle that just barely gets captured.
4. Why is this value important to the PSS team?
We want to capture as many particles as possible, so we're trying to minimize our capture velocity.
5. What type of data does the PSS team collect, and what can be determined from this data?
We collect turbidity samples of the raw water with clay and of the effluent, so that we know how well our system is working.
6. What software does the PSS team use for data collection?
We use process controller.
