Pilot Plant Tube Flocculator Meeting Minutes

Fall 2008 Minutes

October 16, 2008

Accomplishments

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

Outcomes

• Thursdays test was inaccurate due to unclean turbidimeters
• Results from Fridays test seem inaccurate, raw water turbidity is very low. Perhaps line is clogged.

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 figure out why raw water turbidity reading is low.
