Research for the summer of 2008 is will focus in three main areas. The Sedimentation Tank sub-section will focus on continuing research with sludge blanket formation and stability. Another sedimentation tank with lamella technology will also be constructed for comparison. The Tapered Flocculation sub-section will focus on continuing to analyze floc profiles, focusing on ways to create larger flocs faster. Suggested experiments with inline flow obstacles and possibly a redesign of the initial section of the flocculator are proposed. The Automated Flow Control sub-section is focusing on continued research of the linear flow measuring weir as well as the construction and testing of the float-lever chemical dosing system.

- Past Research
- Developing Floc Profiles
- Extend the length of the flocculator to increase Gtheta
- Add obstacles to the beginning sections to increase shear where the floc can handle it
- Redesign the initial sections of the flocculator for baffles to be closer together initially
- Add kaolin clay to the raw water to test technology at higher inlet turbidities
- Run floc profile tests on the previous uniform baffle configuration for comparison
Sedimentation Tank Goals for Summer 2008
- Past Research
- Complete design of the second sedimentation tank with lamella
- Construct second sedimentation tank
- Determine the optimum upflow velocity for sludge blanket formation
- Alter set-up to allow for the inline turbidity meters to sample effluent turbidity from both sedimentation tank.
- Compare sedimentation technologies to determine the most efficient technology
