Accomplishments
- cleaned floc tank Sunday, Wednesday, Thursday and Halloween
- setup the tube flocculator
- manipulated the increment alum dosing in the operator selected state
- attempted to use peristaltic pump with tube flocculator
- replaced tapered baffles with uniform baffles to run increment alum tests
- worked on wiki page
Outcomes
- created turbidity profiles on Sun, Tues, Weds and Fri
- improved our method of creating turbidity profiles, by normalizing data and adding more data points
- replaced soft tubing in the tube floc with rigid tubing.
- Sunday's turbidity profile inaccurate because incrememnt alum dosing was not set
- also cleaning and sampling method varied each test so data cannot be compared
- two tests on uniform baffles will be run next week with increment alum dosing then the uniform baffles will be replaced by the tapered baffles
Issues
- will need functional pumps for tube flocculator
- need to replace bulb on tank light
- understand how to setup and operate increment alum doing with the process controller
