Accomplishments
- cleaned floc tank Mon, Tues, Weds and Fri
- checked turbidimeters and cleaned if necessary Mon, Tues, Weds and Fri
- ran tests with uniform baffle spacing Mon, Tues, Weds and Fri
- attempted to use peristaltic pump with tube flocculator
- worked on wiki page
Outcomes
- created turbidity profiles on Mon, Tues, Weds and Fri
- improved our method of creating turbidity profiles, by normalizing data and adding more data points
- plan on replacing soft tubing in the tube floc with rigid tubing.
Issues
- will need stronger pumps for tube flocculator
- clear tubing used for tube flocculator seems to be warped, letting air get in at the joints
- sink to drain flocs clogs easily, so we now pump the water to another drain while cleaning the tank
- every time the tank is cleaned, the pump that drains the water from the floc tank also drains the sed tank, possibly disturbing the floc blanket
- need to replace bulb on tank light
