3 returning and 1-2 new members

Important team member skills:

• Familiarity with Aguaclara Project
• CEE 4540

Challenges

Floc Tank

• Team members should test consecutive alum doses in order to familiarize themselves with the tank and floc formation
• Compare uniform and non-uniform baffle configuration results from the flocculation tank with high incoming turbidity

Tube Flocculator

• Alter the tube flocculat set-up to minimize air trapped from joints and it has a more permanent location at the plant.
• Set up FReTA to be used with the tube flocculator
• Use FReTA to compare settling velocities at different points in the tube flocculator
• Compare raw water readings from the Pilot Plant FReTA with the laboratory results

Sed Tank

• Discover how much time it takes to form a sludge blanket.
• Can a sludge blanket form if the lamella are present? Can the lamella be designed differently so that this is possible?
• What is the best way to drain a sed tank so aas to cause the least amount of distrubance. How often would this need to occur?
