Challenges for Spring 2009

Subteam Leader: h3. Sarah Long/Colette Kopon

Number of team members needed: h3. max 3

Important team member skills:

• Fluid Dynamics

Challenges

System

• Make the system more robust
  1. Improve the tube settler connection
  2. Stabilize the tube flocculators

Experiments

• Jet dissipation
  1. Run experiments using a mesh with 1 cm diameter holes
  2. Run fluid mechanics experiments to determine the rate of jet dissipation with the cone

• Tube spacings
  1. Vary flow rates with each tube size
  2. Varying Floc blanket height
  3. Vary alum dosage

Process controller

• Use process control incremental method for varying flowrates with each tube spacing
• Set up a system that allows comments to be made without collecting data twice in process controller
• Develop some sort of video recording system to monitor floc blanket growth
