Accomplishments

11/09/08
-removed sutro-weir support structure
-played with alum dosing making sure flow rate stays steady and used tank light to determine optimal floc formation
-bought pvc and created connection, so the inlet doesn't pour in over baffles
-bought pvc pipe to cut to reconfigure uniform spacing
-replaced light bulb in tank light, so we can observe floc formation in the flocculator
11/10
-determined that energy dissipation in uniform flocculator was too low
11/11
-Henry and Christine cut pvc piping for uniform baffles (15cm).

• played with alum dosing instead of increment
  11/12
  -replaced uniform baffles with tapered baffles
  -took apart uniform baffles
  11/13
  -met with Monroe
  11/15
• began to replace with 15 cm spacing but decided against it because there might not be enough energy dissipation
  -alum pump failure due to stamp box disconnection while replacing baffles
  -need to fix stamp box
  11/16
  -fixed stamp box by unplugging/ replugging connections,
• set up siphon to clean tank
  -discussed options for tube flocculator tubing/ set up with Mark
  -discussed options for grounding tank/ need to ask tom
• played with alum dose
  11/17
  -MathCAD tutorial
• determined baffle spacing with minimum energy dissipation requirement of .4 mW/kg

Outcomes

-need to replace baffles in uniform flocculator and end of tapered flocculator with 13 cm spacing
-need to replace baffles/ recut pvc
-Tom is ordering tubing for tube flocculator

Issue

-pump
-electric current in tank
