Pilot Plant Sedimentation Tank Meeting Minutes

Fall 2008 Minutes

September 14, 2008

Accomplishments

• Kellie and Julia went to pilot plant on 9/6/08 for training with Sara.
• Sara, Kellie, Julia and Shaina started plant on 9/10/08. Sarah introduced the team to process controller.
• Team met 9/10/08 and created Fall 2008 task list.
• Team went to the pilot plant to caulk leaky pipe, restring tube flocculator, and secure pipes connecting the lamella.

Outcomes

• The seal between the flocculator and sed tank is ineffective. The plant was turned off so that leaky pipe connecting the flocculator to the sed tank can be caulked.
• caps for pipes were the wrong size
• flocculator was restrung.

Metrics

• N/A

Issues

• If possible a new configuration for tube flocculator will be hung that does not pinch tube.
• need to finish caulking pipe.
• need correct caps to secure lamella
• Next week Shaina and Kellie will work on forming a sludge blanket in the sed tanks once the tube is caulked. Julia and Christine will work on measuring turbidity in the tube flocculator.
