Pilot Plant Tube Flocculator Meeting Minutes

Fall 2008 Minutes

October 16, 2008

Accomplishments

• cleaned floc tank Weds and Thurs
• cleaned turbidimeters and backwashed lines to tube settlers Thurs
• ran tests with uniform baffle spacing Thurs and Friday
• attempted to use peristaltic pump with tube flocculator
• Worked on wiki page

Outcomes

• Weds test was inaccurate due to unclean turbidimeters
• Results from Thurs' test seem inaccurate, raw water turbidity is very low.
• cleared raw water line on Friday by backwashing lines and opening/shutting inlet valve several times.

Issues

• Floc tank will need more regular cleaning from group
• will need stronger pumps for tube flocculator
• sink to drain flocs clogs easily, extra care is needed when cleaning tank to avoid flooding of plant.
• need to replace bulb on tank light
