Accomplishments

11/17/08

• Mathcad tutorial
• determineds energy dissipation in flocculator
• met with Alissa to discuss progress

Tuesday 11/18/08 4:30-8:00

• Talked to Tom about tubing, he will order 100 ft of thicker walled tubing
• also discussed electric shock from lamp in tank. Tom will fix short in the lamp.
• replace second section of the tapered flocculator with 13 cm spacing
• set up 13cm uniform flocculator spacing.
• Recorded data for turbidity levels for approximately one hour.
• Data rendered unusable due to clogs in the tubes leading to the tube settlers and turbidimeters.
• Lines into peristaltic pumps were loose and interfered with readings.
• Clogs removed from the tubes and data collection is resumed.
• Collected turbidity data for approximately one hour.

Thursday 11/20/08
8:30-10:30

• added 10 in tapered baffles to end of 1st section
• ran tapered baffle configuration
• marked 10ft 3 in lengths on tube flocculator
• attempted to set up tube flocculator in figure eight but tubing was too stiff

Friday 11/21/08

• talked to Tom about fittings for new tubing and various other things that can be improved (pumps that could work better, etc)

Saturday, 11/22/08 10:30-1

• switched to uniform configuration, checked plants operations(turbidimeters, etc)
• ran uniform configuration
• set up tube settler while collecting data
• ran hot water through tube settler to increase tubing malleability
• examined data from past experiments

Outcomes

• good data for tapered flocculator hopefully
• tube flocculator is coiled correctly

immediate future tasks

• examine uniform data from today
• connect tube flocculator to tank and pump water through
• measure velocity through tube flocculator
