Summer 2009 team members

• Nadia Siles
• Alex Vandenbergh
• Biniyam Woudie

Summer 2009 Goals

• Rapid Mix Testing: We are attempting to recreate a surface film similar to that found in AguaClara Plants in Honduras in a lab setting.
  • The group will work together and hopes to accomplish this within a three week period
    Week 1: Varying Alum Dosage (35 mg/L, 45 mg/L, 55 mg/L, 65 mg/L)
    Week 2: Varying Turbidity
    Week 3: Varying Location of Alum Addition (above water surface vs below water surface)

• Non-Linear Dose Controller: We need to revise the MathCAD code before constructing a fully functional model.
  • The group will work together and hopes to accomplish this after completing our first goal.
    Week 4: MathCad Revision
    Week 5: Construction of Level Arm
    Week 6: Assembly of Non-Linear Dose Controller
