System

  • make Make the system more robust
    some sort of holder or structure for the flocculator 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
    -varying 1. Vary flow rates
    -varying floc blanket depth
    -alum dosage?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
