...
- All group members will be working on this for the week of Feb 9th
...
- Each group member will have a design to build independently (Feb 16)
...
- Rustom (Feb 22)
...
- Full group (Feb 23)
New Baffle System
- Build new baffle system that can be constructed quickly that allows for easy modification of baffles at the Pilot Plant
- Subteams of two from the PP team will be constructing a row of baffles for each of the floc tank channels.
- Install new baffles
Automatic Alum Dosing
- Research affects of turbidity, temperature, pH, etc. on alum dosing
- Determine formula for appropriate dosing based on above measures
- Incorporate formula into Process Controller to automatically change alum dose with inflow raw water turbidity and temperature
Develop Flocculator Performance Curves
...
- Run the plant, fix any leaks or problems
- Art, Mike (after new baffle system is in place, early March)
- Begin research on dose controller at the pilot plant and construct
- Rustom, Lalo (beginning of March). Collaborate with dose control group.
- Determine procedure for taking turbidity profiles
- Collect turbidity profiles for different baffle arrangements and tapered vs. non-tapered arrangements
- Art, Mike (this will be ongoing for several weeks)
- Calibrate all turbidity meters (Ian has the standards)
- Develop protocol for plant maintenance to ensure that collected data is not affected by dirty turbidimeters
- Develop plan to set alum dose appropriately.
- Compile data, analyze, graph results
- Rustom
-FReTA Comparison_
- Set up FReTA to be used with the tube flocculator and use to compare settling velocities at different points in the tube flocculator
- Jeff (March). Collaborate with Ian.
- Jeff
- Jeff (March). Collaborate with Ian.
- After completion of these challenges, formulate challenges for sedimentation tank and begin research there
- Full group. After completion of aforementioned goals.
