Pilot Plant Sedimentation Tank Meeting Minutes

Fall 2008 Minutes

September 18, 2008

Accomplishments

• Julia and Kellie finished caulking the pipes.
• Team reviewed wiki pages.
• Team met at pilot plant on 09/18/08.
• Julia discussed with Sarah the configuration of the tube flocculator and the alum dose needed to form a floc blanket over time.
• Team goals for the semester were updated.

Outcomes

• Could not fully start up the plant because some of the caulk is not dry.
• Much of the sludge build-up was pumped out of the tank.
• Work on the wiki page was discussed and divided up among the sub-teams. Christine will work on the Tube Flocculator pages, while Kellie and Shaina rearrange different parts of the Sedimentation Tank page.

Issues

• Our method for pumping sludge out of the tank is unnecessarily time-consuming. We will try to find a different way.
• Since we could not start up the plant, Shaina will return on 09/19/08 to check the caulk and begin the running the plant with a 20 mg/L alum dose if the caulk is dry. We need to run the plant consistently at this concentration for some time before we can form a floc blanket.
